When are grapes ripe?

Ripening Of Grapes: When To Harvest Grapes

In my neck of the woods, the Pacific Northwest, it seems every other day a new winery pops up. Some of them make it and some of them don’t; the result not only of savvy marketing but the quality of the wine which directly correlates to the superiority of the grape. For the home gardener, growing grapevines may create a lovely shaded oasis or arbor, or an ornamental detail with the added bonus of edibility. But how do you know when to harvest grapes at the peak of their sweetness and optimum flavor? Read on for some grape harvest info.

When to Harvest Grapes

The precise time for picking grapes is dependent on the location, length of growing season, variety of grape, crop load and the intended use of the grape. Heavy crop loads take longer to mature. The optimum time for harvesting grapes will vary year to year as do environmental conditions — sometime after the berries turn color (veraison).

Commercial grape growers rely on more scientific methods to determine when to harvest the grapes such as precise pH levels and sugar contents (Brix) that are established with testing. The home grower may make use of the following to ascertain the ripening of grapes and proper harvest time:

Color – Harvesting grapes for use in jellies or wine making must occur at just the right stage of maturity for maximum sweetness. Grapes change color from green to blue, red or white, depending upon the variety. Color is one of the indicators of ripeness. However, it is not the most reliable indicator, as many varieties of grapes change color well prior to ripening. Still, when completely ripe, the whitish coating on the grapes becomes more evident and the seeds turn from green to brown.

Size – Size is another gauge of the ripening of grapes. When mature, the grapes are full size and a bit less firm to the touch.

Taste – Hands down, the best way to ascertain if your grapes are ripe enough to harvest is to taste them. Sample the grapes three to four weeks prior to the approximate harvest date and continue to taste the grapes as they mature. Try to take samples at the same time of day from a variety of areas on the vine.

Grapes, unlike other fruits, do not continue to ripen once off the vine, so it is important to keep tasting until the grapes are uniformly sweet. Sample from sun exposed areas as well as those that are shaded. Ripeness and color of grapes is not reliant upon direct sunlight, but rather the amount of light that reaches the grape foliage results in high quality fruit. It is the leaves of the grape that engender the sugars, which are then transferred to the fruit.

Additional Grape Harvest Info

Uneven ripening may occur due to too many grape clusters on the vine (over-cropping), potassium deficiency, drought or other environmental stressors. Warmer than normal weather is often the cause of uneven ripening, wherein some berries stay sour, hard and green while others ripen and darken in color normally.

Ripening berries are also extremely attractive to the birds. To protect the impending harvest, you may want to envelop the grape clusters in a brown bag tied to the cane or by netting the entire vine.

Once you have ascertained it is prime time for a grape harvest, simply remove the clusters with hand shears. Grapes can be stored at 32 F. (0 C.) with 85 percent relative humidity, in a perforated bag for up to two months.

Food Storage – How long can you keep…


  • How long do grapes last? The precise answer to that question depends to a large extent on storage conditions – for maximum shelf life, keep grapes refrigerated at all times.
  • How long do grapes last at room temperature? Grapes should only be left out at room temperature if being consumed within the same day, as grapes are highly perishable and do not ripen after being picked.
  • Refrigerate grapes in perforated plastic bag; discard any bruised or moldy grapes before refrigerating.
  • To extend the shelf life of grapes, do not wash the grapes until ready to eat or use.
  • How long do grapes last in the refrigerator? Properly stored, grapes will usually keep for about 7 to 14 days in the fridge.
  • Can you freeze whole grapes? Yes, to freeze:(1) Take off the stems, wash grapes carefully in cold water, pat dry and place in a single layer on cookie tray in freezer; (2) Once grapes are frozen, transfer to airtight containers or heavy-duty freezer bags and return to freezer.
  • How long do whole grapes last in the freezer? Properly stored, they will maintain best quality for about 10 to 12 months, but will remain safe beyond that time.
  • The freezer time shown is for best quality only – grapes that have been kept constantly frozen at 0°F will keep safe indefinitely.
  • How to tell if grapes are bad or spoiled? Grapes that are spoiling will typically become soft and mushy and their color will deteriorate; discard grapes if mold appears or if the grapes have an off smell or appearance.

Ensure your fruits and vegetables stay fresh longer by storing them properly. After giving produce a quick cleaning, knowing where to keep them means they’ll be wonderfully crisp or as sweet as possible when you’re ready to enjoy.

Instead of tossing spoiled fruit, which is basically the same as throwing your money away, try these tips for storing fruits and veggies so they last longer:

  • Use produce bags. Store fruits and vegetables in breathable produce bags so they are able to absorb moisture and air. When kept in sealed bags, fruits and vegetables break down quicker.
  • Watch out for cold-sensitive items. Storing potatoes, onions, and garlic in cool, dark spots elongates life for up to a month. But these cold-sensitive items don’t do well in the fridge, where temps dip too low for their liking.
  • Know your ethylene produce. Certain fruits and vegetables release ethylene, which speeds the ripening process. Apples, apricots, cantaloupe, and honeydew are best kept in the fridge to keep them fresh longer. But store separate from greens! The ethylene emitted will wilt your future salad.
  • Leave some produce out of the fridge. Other ethylene emitters, such as avocados, bananas, peaches, nectarines, tomatoes, pears, and plumbs, are best kept on the counter and can be tossed in the fridge once ripe to lengthen shelf life. Store separately to keep them from ripening too quickly.
  • Dry your washed veggies. It’s a good idea to wash fresh greens, but tossing them in the fridge while damp may make them soggy. After rinsing, pat dry, wrap in paper towel, and store in an open container in the fridge.
  • Put grapes on a paper towel. Grapes have a tendency to mold due to moisture build-up. Remove grapes from the bag or container the fruit came, wash, and gently pat dry. Place on a paper towel in an open container and pop in the fridge.
  • Don’t wash your mushrooms. Mushrooms don’t enjoy a washing, and are best stored in a sealed container in the fridge.
  • Place stone fruit on counter. Keep stone fruit on the counter until fully ripe and then pop in the fridge to keep it sweet longer.
  • Keep peppers in a bag. Place peppers in a paper or produce bag and store in the fridge. They’ll stay crisp for a couple of weeks.
  • Separate bananas. Prolong the life of bananas by separating them from the bunch, which slows the ripening process.
  • Remove berries from containers. Berries are delicate things, and don’t like moisture. Remove from containers they came in, gently wash and pat dry, and place in a single layer on a paper towel in an open container. Store in the fridge.
  • Store citrus fruits on the counter. Citrus fruits do just fine when stored at room temperature. Instead of displaying in a bowl, simply let the fruit hang out on the counter to resist mold growth.

Grapevine is an interesting plant not only that it produce some of the best fruit on earth which can be transformed into the wine, but also as the plant itself. Grapevine is a permanent plant but differs from other permanent plants in many ways. So, in order to successfully maintain vine and produce the best possible grapes and thus the wine, it’s important to know each and every grapevine parts and it’s functions. For this reason, we have decided to make a series of posts on grapevine structure.

In the first part, we will shortly introduce all the basic parts of grapevine.

Grapevine is a climber which naturally grows on the trees and bushes, high and in wide shapes. In the vineyard its growth is maintained with the pruning in order to control the quantity and quality of the grapes.

Like any other plant also grapevine has its underground and above-ground part. The underground part consists of an underground trunk with the root system. While the above ground part consists of the trunk, canes, and shoots. On the one-year-old shoots, there are leaves, tendrils, flowers, and grapes.

Root system – the roots of a grapevine are multi-branched structures that grow to various depths into the soil depending on the variety (rootstock), soil and climate. Some varieties develop very deep and almost vertical roots while others have very flat and shallow roots system and therefore requires deep, fertile soil.

Trunk – is the main steam, it’s permanent and supports the above-ground vegetative (leaves and stems) and reproductive (flowers and fruits) structure of the vine. The height of the trunk and also its branched varies with the selected training system. In cane-pruned training system, the top of the trunk is called the head. Fully developed trunk has arms – short branches from wich canes and spurs originate. Depending on a selected training system arms are located in different positions. In training system that utilize canes (cane-pruned training system) – one-year-old wood arise from arms usually near the head of the vines. While in training system that utilizes cordons (cordon training with spur pruning) arms are spaced at regular intervals along their length. *Cordons are extensions of the trunk that usually grows horizontally along a trellis wire.

Canes – When the shoots mature and woody, it becomes a vine cane. Canes if therefore one year old, woody and, matured shoot; after the leaves has fallen off. Canes are the main concerns for winegrowers during the dormant season. With the winter pruning of canes, winegrowers are managing vine size and shape and therefore control the quality of crop in the coming season.

Buds – develop in the leaf axil, right above the connection between the shoot and leave petiole. Inside each bud, there are three distinct growing points, each capable of producing a shoot, also known as primary, secondary and tertiary buds. Bud is actually a highly compressed shoot with all its parts, including cluster. At bud burst normally primary bud begins to grow, but sometimes also secondary or tertiary buds, so there can be two or three shoots on the same axil. In case the primary bud is damaged or freezes, then the secondary or tertiary buds grow in place of the primary bud. In comparison to the primary bud secondary and tertiary buds generally, have little to no fruit.

Shoots – are green stems which develop from buds, and represent the primary growth structure of grapevines. The shoots that arise from primary (winter) buds are normally the fruit-producing shoots. The shoot consists of stems, leaves, tendrils and fruits. *Canopy is a collective term that is used to describe the shoots, leaves, and fruits of the grapevine.

Leaves – The leaves of the grapevine, as any other plant, provide nourishment and air for the plant. Leaves are converting sunlight into usable energy for the plant. More leaves are well sunlit more organic compounds the grapevine can use for its growth. The shape and size of leaves are determined by the grapevine variety, as well as color, which varies from light to dark green.

Tendrils – are a slender structure that appears on the top and sides of stems. They grow until the grapevine is ready for harvest, after the harvest they become wooden in nature. Since the grapevine is a climber it needs tendrils to coil around small objects such as fences, trellises, etc. to reach up for the sun and heat. Tendril and flower cluster have a common development origin, therefore, we might find flowers design developed at the end of the tendril.

Flowers and Grapes – Flower cluster grow on the opposite site then leaves along the shoot. Most fruitful shoots develop from one to three flower clusters depending on the variety and growing conditions. Each cluster may contain only a few or up to several hundred flowers at the time of bloom; the number depends on the variety and environmental conditions. When fertilized, the flower clusters develop into clusters of grapes – the fruit set – and the berries start to grow.

For the best batch of organic grapes (Vitis), it is essential to pick the grapes when they are ripe. See below for ways you can test for ripeness.

Tasting is the best test for maturity. If grapes are sweet and flavorful, they are ready to pick.

The next best guide is color. Green varieties, such as ‘Romulus’ and ‘Thompson Seedless,’ turn whitish or yellowish; black and red varieties take on an added depth of color.

If you see birds on the vines, it is a good guide to ripeness. Once grapes have been picked, they will not ripen further. Therefore, wait until your crop is fully mature, then harvest by clipping off the bunches with scissors or a sharp knife. Pick them on a dry day because wet grapes do not keep as well. Discard overripe, withered or diseased grapes soon after picking before they spoil the bunch.

Grapes that are intended for raisins, such as ‘Thompson Seedless,’ should be left on the vine somewhat longer than wine or table varieties in order to increase the sugar content. Grapes to be used for jelly can be picked before they are fully ripe.

Grapes can be stored for several weeks at a temperature of about 32°F (0°C) and a humidity of 90 percent.

Grape harvesting is one of the most important procedures for grapevine producers. In many countries, the day of harvesting is so great that producers organize fiestas to celebrate the great event.

Harvesting period for grapes, generally starts 30-70 days after fruit set, by the time berries change color from green to yellow (for white varieties), or red-purple (for red varieties). During this stage, we normally have an increase in sugars and a decrease in acids inside the fruits. In general, in the northern hemisphere, most varieties mature from August since November, while in the southern hemisphere from March to August.

However, it is not easy to define the right harvesting time for grapes. Environmental conditions, the soil type, the location of the variety, and the growing techniques play a crucial role in the quality of the final product. Producers harvest different types or varieties on different maturity stages, in order to achieve desired quality characteristics.

Producers need to define specific characteristics such as:

For red wine-producing grapes

  • The sugars- acids proportion
  • The phenolics content
  • Tannins
  • Flavons

For white wine-producing grapes:

  • The sugars – acids proportion
  • The flavorings

For table grapes :

  • The sugars – acids proportion
  • The size

For this reason, during the final maturity stage, from veraison to color change, producers perform daily weather monitoring together with a grape examination, so as to prevent possible infection or damage.

Most producers use Portable Refractometers that measure the sugar content of the grapes, in order to decide if the crop is ready for harvest or not. These Portable Devices determine the Degrees Brix. Degrees Brix (or just Brix) is a measure of sugar content. 1o Brix is equal to 1 g Sucrose in 100g of Solution. Brix method is universally used for determining fruit maturity, potential alcohol yield for wine varieties, and sugar content. In general, wine grape varieties are harvested at 12-24 degrees Brix, while table grape varieties are normally harvested at 12-20 degrees Brix. Seedless table varieties are harvested at 16-20 degrees Brix, while table grapes with seeds are normally harvested at around 13-14 degrees Brix.

Hand-harvesting of Grapes

In most cases, grapes are hand-harvested. Hand-harvesting is performed using knives and/or shears, either manual or electric. After whole bunches are cut, workers place them in collection baskets and transfer them to the winery (wine varieties) or to special warehouses (table grapes varieties). Table grape varieties can only be harvested by hand. They cannot be harvested mechanically, because they will be bruised. After harvested, table grapes are cooled and transferred to packaging warehouses.

Mechanical Harvest of Grapes.

This method is used exclusively for wine varieties. Sophisticated machines travel through the vineyard rows and use rubber or other materials to shake the vines so that the grapes will fall to a conveyor belt. Once collected, foreign materials are removed through a series of webs, and finally, grapes are collected to a special deposit. They are then immediately transferred to the winery. These harvesting machines cost hundreds of thousands of dollars. However, many producers report that they find great difficulty in employing many trained workers at the exact time of harvesting. Thus, they consider shifting to Mechanical Harvesting of Grapes, so that they can harvest a great area of vineyard at one day, without having to worry about finding and employing groups of trained workers. Nevertheless, mechanical harvesting is not suitable in the case of grapes with very thin skin. In such a case, a great portion of grapes will surely break, something that may lead to oxidation and bacterial growth.

Grapes are sensitive fruits. Right after harvesting, producers try to transfer them as quickly as possible either to the packaging facilities (table grapes) or to the winery. For table grapes that need to be transported for long distances, refrigerator tractors are required.

How You Can Grow Larger, Sweeter Grapes

QUESTION: Is it true that snipping off the bottom of each bunch of developing grapes will make the fruit larger and sweeter? If so, how much do I take off, and does it pertain to all varieties?

ANSWER: In home gardens it is possible to obtain larger, sweeter fruit on some grape varieties by removing the lower one-third to one-half of each cluster as soon as grapes begin forming in spring. Although home-grown grapes rarely can achieve the size of commercially produced ones, the varieties that respond most favorably to this treatment are Thompson Seedless, Perlette, Cardinal and Ruby Seedless (King’s Ruby). It’s a little late to do it this season, but if done immediately you might still obtain sweeter fruit.

What to Do About ‘Tobacco Budworm’

Q: Is there anything that can be done to control or eradicate the “Tobacco budworm” that is destroying my geraniums and petunias? I’ve given up on them.


A: This ubiquitous caterpillar can be quite a nuisance, but two products give hope to the gardener. One is a chemical spray called Sevin. According to Sunset, Sevin is “reasonably safe to use” and “is a champion at killing chewing insects, but . . . it (also) kills honeybees and numerous (insect) parasites and predators.”

A popular alternative is Bacillus thuringiensis, sold sometimes as B.T., Dipel, Thuricide and Biotrol. This product “contains bacteria that destroy digestive processes in caterpillars (so they stop eating and eventually starve to death); it is harmless otherwise,” according to Sunset’s researchers.

Both will work, so maybe now you can finally enjoy your geraniums and petunias.

How to Control ‘Rust’ on Rose Leaves


Q: For three years I have battled “rust” on my roses. Fungicide spray helps some, but isn’t there any means of controlling this disease?

A: Rust is a very annoying fungal disease that causes a reddish powder to form on the underside of rose leaves, usually in the springtime. Infected plants look sickly, and flowers are of inferior quality. Spores of this fungus are airborne and ever present. They become active when night temperatures are cool, day temperatures are fairly warm and the air is most. Some varieties of roses are more susceptible to this disease than others and, where conditions are right, will almost always get the disease first. Then from these plants the infection may spread to others nearby.

Spraying every four to seven days with Benomyl, from early March through mid-June, helps but does not solve the problem; and it is an impractical nuisance.

Unfortunately there is no magic wand to wave and make the problem go away completely. However, here are some fairly simple solutions, which will reduce–and maybe eliminate–the problem as a matter of practical concern:

1–At the first sign of infection in the springtime, remove all infected leaves from the garden area.

2–When you prune your roses in the wintertime–anytime from Thanksgiving to Valentine’s Day–be sure to remove all leaves from the plants and any leaf or stem debris from the garden area.

3–If one variety always seems to get the disease first or early in the season, dig it out and destroy it. You may replace it with a different variety.

How to Store Grapes So They Last Longer

Grapes are surprisingly fickle fruits. If you don’t store them correctly, they can shrivel up or even get moldy. But when you consider the fact that grapes are actually berries, and berries have a notoriously short shelf-life, it’s kind of surprising that grapes last in your fridge as long as they do. In fact, if stored correctly, regular table grapes can stay fresh for long time. As Harold McGee explains in On Food and Cooking: The Science and Lore of the Kitchen, “Thompson seedless grapes,” which are the most common type of table grape in the United States, “picked in the cool of the morning and treated with antimicrobial sulfur dioxide can be held for as long as two months at 32°F/0°C.”

Chances are good, however, that the grapes you buy at the grocery store won’t last a full two months, even if you do keep them at 32°F. You should store grapes in the refrigerator though, since grapes do best in the cold. As the experts from the California Table Grape Commission explain, the optimal storage conditions for grapes is 30-32°F with high humidity, about 90-95 percent. This is why the best place to store grapes is in the high humidity crisper drawer in your fridge.

But remember that high humidity is different than exposure to moisture. Keep your grapes away from direct contact with water, and store them unwashed, because the excess moisture will decrease their shelf life, according to the California Table Grape Commission. Your grapes should also be kept away from a “cooling unit’s direct air path,” they write, because that’ll speed up the dehydration process and cause your grapes to shrivel up.

You do, however, want to keep grapes well-ventilated. That’s why our friends at Real Simple recommend storing grapes you buy at the grocery store in the original plastic packaging, which usually has holes in it to allow for some air flow. But don’t keep that bag or box near vegetables or foods with a strong odor. (I’m looking at you, onions.) If you do, your grapes will start to take on those smells.

Once you’re ready to eat the grapes that you’ve so carefully stored, all you have to do is wash them in cold water and enjoy.

How long do grapes last in the fridge or at room temperature? Grapes are definitely one of the most popular fruits around. So many people turn to grapes in order to satiate a sweet tooth. These delicious fruits can be used to make some tasty treats and they’re also just great to eat on their own. If you like to keep grapes stocked in your kitchen, then you already know how good they are.

You might be curious about just how long grapes are supposed to last, though. When you store grapes properly, they should be able to last for several days. If you’re just keeping the grapes on your kitchen counter somewhere, then you can expect them to last for between three and five days. Grapes stored in your refrigerator will do a little bit better and can last somewhere between five and ten days.

It’s also possible to freeze grapes in order to extend their shelf lives even longer. When you put grapes in the freezer, they can be stored for between three and five months before going bad. This is quite a long time to be able to store grapes so it’s good to consider this if you aren’t sure about what to do with your grapes. As always, you need to remember that produce doesn’t have a “best used by” date printed on the packaging so you need to be mindful about how long it has been since you bought them.

How Can You Tell If Grapes Have Gone Bad?

You can tell that grapes have gone bad by using your own senses and inspecting the grapes. When grapes are starting to go bad, you’ll likely notice that they have an even softer texture than usual. You might even notice that they have a brown type of discoloration. Eventually, the grapes are going to start smelling similar to vinegar when they start to ferment.

As the grapes continue to deteriorate, mold will start to appear. Once this occurs, it’s going to be time to cut your losses and throw the grapes out. You always want to discard any rotten grapes that you come across. Eating grapes when they are deteriorating is not recommended and you could even get sick.

When you’re choosing grapes at the produce section of your local grocery store, it’s always best to choose the healthiest grapes that you can find. For the best results, the stems on the grapes should be green and in good shape. You’ll also want to choose grapes that are plump and not overly soft. Choosing fresh grapes ensures that you’ll be able to use them for longer whereas grapes that are closer to the end of their lifespan will only last for a couple of days once you get them home.

How Can You Store Grapes to Get Them to Last Longer?

When you want to get your grapes to last as long as possible, you need to pay attention to how you’re storing them. Grapes should ideally be stored in a plastic bag that has ventilation. In fact, grapes are often sold in plastic bags with holes at the bottom for this reason. You should be storing your grapes in the refrigerator if you want them to last for as many days as they can.

It’s also important to note a few things about grapes before continuing. Grapes are known to absorb odors and this can be a problem when you place them next to certain other food items in your refrigerator. You might want to avoid placing grapes near foods such as onions or garlic. Grapes can be placed in an airtight container before being put in the fridge too but you’ll want to make sure that there is no moisture present before doing so.

Freezing grapes will allow the grapes to last for several months. Many people actually really like having frozen grapes as a snack. You should rinse your grapes before you freeze them and you’ll also want to put them on something solid, such as a cookie sheet. You can freeze the entire cookie sheet and then place your grapes into a freezer bag for safekeeping.

Advice for Using Grapes Before They Go Bad

If you have some talent for canning, then you might be able to go ahead and make some grape jam. Grape jam can be very delicious when used to make sandwiches. Many people like to pair grape jam with peanut butter as a tasty snack. To make this jam, you just need to slip the skins from your grapes and then puree them.

Stirring together lemon juice, peeled grapes, and a bit of sugar is the next step. Admittedly, making grape jam is a bit of a process. It involves slowly boiling and then canning or placing the jam in jars. Even so, it’s a very delicious thing that you could do with leftover grapes that you don’t think that you can use in time.

Another idea is to go ahead and make a fruit salad for your family to enjoy. Fruit salad is a nice treat for people to have and it allows you to use up several types of fruit that you might have around the house. Grapes keep pretty well when used as a part of a fruit salad. This is very easy to whip up and it’s something that most people will really enjoy.

If you don’t have any other ideas for your grapes, then freezing them is going to be the best course of action to take. Freezing grapes really does allow you to eat them for longer periods of time. It gives you months to finish eating grapes rather than just having several days. If you don’t have the energy or equipment to make grape jam, then just freeze the grapes and enjoy them that way.

Special Grape Facts

Did you know that there are actually many different types of grapes? You might be familiar with common variants such as concord grapes but there are actually more than eight thousand grape varieties that come from sixty species. There are likely far more types of grapes than you ever would have realized. People have been cultivating grapes for eight thousand years at this point so it makes sense that grapes are so varied.

Another interesting fact is that grapes are actually considered to be berries. It makes sense when you think about it but they aren’t the first fruit that you’d think of when someone brings up the word “berry.” These delicious fruits are among the most popular natural snacks in the world. They’re also used to make wine.

The types of grapes that are used to make wine differ from table grapes that you are meant to eat. Grapes are also used to make raisins. Raisins are just dried-out grapes but they do have a very distinct taste of their own.

In Conclusion

Now that you understand how long grapes can last, you’ll be able to plan accordingly. Grapes aren’t going to last for too long when placed on the counter. They’ll do better being put in the refrigerator but you shouldn’t expect them to stay good for longer than ten days under optimal conditions. Depending on how quickly you eat grapes, this might be more than enough time to get through a bunch.

Grapes will last longest when you decide to go ahead and freeze them. This is an easy way to get grapes to last for several months. If you aren’t sure what to do and you want to prolong the shelf life of your grapes, then you should simply freeze them. They’ll be tasty this way and you could even consider packing them in lunches.

Frozen Grapes – An Amazing Snack!

Frozen grapes are the best snack ever! Especially in the summer. They’re super refreshing, incredibly healthy, low-calorie, and SO easy. I mean you actually don’t have to do anything except putting them in the freezer. And they kind of taste like frozen candy. It’s just INCREDIBLE!!

The only thing I’m thinking right now is why haven’t I tried frozen grapes earlier?!

I’ve read about frozen grapes before, but until last summer I haven’t tried eating them as a snack. Boy, was I missing out! I’ve always liked grapes, but I do LOVE them when they’re frozen.

So maybe there are other people like me being late to the game, so here I am writing a post about frozen grapes.

You can use both, red and white grapes. I think I like white grapes a little bit better, but they’re both amazing! It’s the only way I’m eating grapes these days. Haha! And I’m eating A LOT of them.

When you’re a normally a fan of grapes, you just have to give this a try! I usually just wash the grapes, put them in freezer bags, and then freeze them overnight. So it’s only grapes, nothing else.

Frozen Grapes with Sugar:

But I’ve also read that many people coat them in sugar before freezing them. I haven’t tried this yet because I think they’re sweet enough just by themselves.

I don’t know if it’s just me, but I got the feeling they’re a lot sweeter when they’re frozen. But if you want to add a little bit of additional sweetness, you could give this a try.

And they’re many other recipes for frozen grapes with caramel, jello, or even with chocolate! Yummy!

Freezing Grapes – How to Make Frozen Grapes

I guess you will all believe me when I tell you that this is the EASIEST “recipe” on my blog. Haha! All you need is 5 minutes of your time. Then just give your freezer another 8 hours to make perfectly frozen grapes for you.

STEP 1: Put the grapes in a colander and rinse them with cold water for about 30 seconds. Gently rub them as you rinse them. Grapes belong to the “Dirty Dozen” (products that have the highest concentration of pesticides), so this helps to remove bacteria and pesticides on the grapes.

STEP 2: Check for any broken or decaying grapes and remove them. Gently pull the rest of the grapes from the stem.

STEP 3: Fill the washed and pulled grapes in a ziploc bag.

STEP 4: Freeze the grapes overnight or for at least 8 hours.

What To Use Frozen Grapes For:

1. Snack:

I usually just eat frozen grapes as a healthy and delicious snack. Especially in the summer.

2. Frozen Grapes in Wine:

Frozen grapes are also great to chill wine. Unlike ice cubes, they don’t water down your drinks. Red grapes are perfect for red wine and white grapes for white wine. No big surprise. Haha!

And when you’re done with your wine, you got a delicious snack waiting for your on the bottom of your glass.

3. Weight Loss:

Frozen grapes are also great for weight loss. I mean when you’re on a diet and want to lose weight, you often get sugar cravings. Instead of candy just eat a bowl of frozen grapes.

And the best thing is you don’t have to feel bad about it and you can even go for more!


I hope you like frozen grapes as much as we do around here! What’s your favorite summer snack?

If you give these frozen grapes a try, I’d love to know what you think about them. Just leave me a comment and a star rating below. Your comments really make my day!

  • 3 cups red or white grapes or as many as you want!


  • Put the grapes in a colander and rinse them with cold water for about 30 seconds. Gently rub them as you rinse them. Grapes belong to the “dirty dozen” (products that have the highest concentration of pesticides), so this helps to remove bacteria and pesticides on the grapes.
  • Check for any broken or decaying grapes and remove them. Gently pull the rest of the grapes from the stem.
  • Fill the washed and pulled grapes in a ziploc bag.
  • Freeze the grapes overnight or for at least 8 hours.
