The wine made from frozen grapes is called ice wine, or Eiswein in German. It is made by pressing grapes while they are naturally frozen on the vine, concentrating their sugars, acids, and flavors into a small amount of rich juice.
Ice wine is usually sweet, but its acidity helps keep it lively rather than cloying. This guide explains how it is made, how it differs from other sweet wines, which grapes and regions are known for it, and what to look for when buying a bottle. You’ll also find practical serving, pairing, and storage tips, plus a simple way to spot wines that are frozen after harvest instead.
Which wine is made from frozen grapes?
Ice wine is the wine made from grapes that freeze naturally on the vine. Once the grapes are frozen, they are picked and pressed while still frozen. The ice crystals hold much of the water, so the press yields a small amount of concentrated juice for fermentation.
The German name is Eiswein. In Canada, the name is commonly written as Icewine, while “ice wine” is also widely used in English. Although spellings and regulations differ by country, the central idea is the same: grapes freeze on the vine before they are harvested and pressed.
That distinction matters. A winemaker can also freeze harvested grapes in a controlled setting to concentrate their juice. This method is often called cryoextraction, but a wine made that way is not necessarily legally entitled to the name ice wine or Icewine. The label and the rules in the wine’s country of origin determine what the term means.
How ice wine is made
Ice wine depends on a naturally cold winter. Growers leave healthy grapes on the vine after the usual harvest, allowing them to become very ripe. The fruit must stay in good condition through changing weather, pests, and the risk of rot. Then temperatures fall enough for the grapes to freeze.
Harvest generally happens during a cold spell, often at night or before sunrise, when the fruit is still frozen. Workers pick and press the grapes quickly. During pressing, frozen water remains as ice while concentrated juice runs from the press. The juice contains high levels of sugar and acidity, along with the grape’s aromas and flavor compounds.
Yeast ferments the juice, turning some of its sugar into alcohol. Because the juice is unusually concentrated, fermentation can be slow and may stop while considerable natural sugar remains. The result is typically a sweet wine with a vivid, fresh edge.
The process depends on more than low temperature. The grapes need to be healthy and ripe, and they must freeze on the vine before harvest. If the crop spoils or the winter does not provide suitable conditions, the producer may not make ice wine that year. This weather risk, the extended time in the vineyard, and the small juice yield help explain why these bottles are often costly.
What does ice wine taste like?
Expect pronounced sweetness, but do not assume every bottle tastes alike. The grape variety and growing region shape the wine’s aromas and texture. Common flavors include peach, apricot, mango, citrus, apple, pear, honey, and floral notes. Some bottles also show tropical fruit or a hint of spice.
Acidity is the counterweight to sweetness. It gives the wine a bright, refreshing quality and keeps the finish from feeling heavy. A well-balanced bottle can taste luscious without seeming syrupy. The exact balance varies, so check the producer’s notes or ask a wine retailer if you prefer a lighter or richer style.
Ice wine is usually enjoyed in small pours because it is concentrated and sweet. It can be served as dessert, alongside food, or as a dessert course on its own. It is not simply grape juice: it is fermented wine, and its alcohol level varies by bottle.
Ice wine compared with other sweet wines
Several wines can be sweet, but the grapes and production methods differ. The clearest way to tell them apart is to ask what happened to the fruit before pressing.
| Wine style | How the grapes are prepared | Typical character | Best for |
|---|---|---|---|
| Ice wine | Grapes freeze naturally on the vine, then are picked and pressed while frozen. | Concentrated sweetness balanced by bright acidity. | A special dessert pour or a pairing with rich, salty, or fruit-based foods. |
| Late-harvest wine | Grapes remain on the vine longer to ripen beyond the usual picking time. | Ripe fruit and sweetness; style varies by grape and region. | People who want a sweet wine without the specific frozen-grape method. |
| Botrytized wine | Grapes are affected by beneficial mold, often called noble rot, which dehydrates them. | Rich, concentrated flavors that can include honey and dried fruit. | Pairing with complex desserts, savory foods, or blue cheese. |
| Passito or dried-grape wine | Picked grapes are dried after harvest to remove water before pressing. | Often rich and full-bodied, with ripe or dried-fruit flavors. | Those seeking a dessert wine made by drying rather than freezing grapes. |
| Wine made with frozen harvested grapes | Grapes are frozen after picking, often through a controlled process. | Can be sweet and concentrated, but rules and names vary. | Shoppers comparing styles; check the label for the exact method. |
These methods can produce similar levels of sweetness, but they do not make the same wine. In particular, “late harvest” does not mean the grapes froze, and “frozen grape wine” does not automatically mean grapes were frozen on the vine.
Which grapes and regions are associated with ice wine?
Germany and Austria are associated with traditional Eiswein. Canada is also a major producer, and its cold winters can provide the conditions needed for grapes to freeze naturally on the vine. Producers in other cold regions may make ice wine as well, when the weather and local rules allow.
Riesling is a familiar choice because its lively acidity can balance concentrated sweetness. In Canada, Vidal is another well-known variety, valued for its ability to withstand cold conditions and retain expressive fruit flavors. Producers may also use grapes such as Gewürztraminer or Cabernet Franc, depending on the region and style.
There is no single grape that defines ice wine. If you prefer citrus, apple, or floral notes, look for a Riesling-based bottle. For ripe peach or tropical fruit, Vidal may suit you. Cabernet Franc ice wine can show red-fruit character. These are useful starting points, not guarantees: climate, vineyard, harvest conditions, and winemaking all affect the final taste.
How to choose a bottle
Start with the label. Look for “ice wine,” “icewine,” or “Eiswein,” and check the country or region of origin. If the production method matters to you, read the producer’s description to confirm that the grapes froze naturally on the vine. Words such as “frozen” alone do not always tell you when or how the fruit was frozen.
- Choose a grape style. Riesling often brings citrus, apple, and floral aromas. Vidal commonly offers ripe stone-fruit or tropical notes. Cabernet Franc can lean toward red fruit.
- Consider the sweetness and acidity. Ice wine is generally sweet, but acidity shapes how fresh it tastes. If you dislike heavy desserts, ask for a bottle described as bright or balanced.
- Check the bottle size and serving plan. A little goes a long way. A smaller bottle may be practical if you plan to pour only a few glasses.
- Read the producer’s serving suggestions. These can help you match the wine with food and serve it at a suitable temperature.
- Buy from a reliable retailer. Proper storage matters for wine quality. Choose a seller that keeps bottles away from heat and strong light.
Price is influenced by the labor, weather risk, and limited juice yield involved, but a high price alone does not guarantee that a bottle suits your taste. When possible, choose by grape, region, and tasting description. A small pour at a tasting is a useful way to compare styles before buying.
How to serve and pair ice wine
Serve ice wine chilled, but not so cold that its aromas disappear. If the bottle has been stored in a refrigerator, pour a small glass and let it sit briefly. The changing temperature can make fruit and floral notes easier to notice. Follow the producer’s guidance if it gives a specific serving recommendation.
Use a small dessert-wine glass or another glass that lets you appreciate the aroma. You do not need a large pour. A modest serving is enough to show the wine’s sweetness and acidity, and it leaves room for food if you are serving it with a meal.
For pairings, aim for contrast or a matching level of sweetness. Salty foods can make the fruit seem more vivid, while tart fruit can echo the wine’s acidity. Good options include:
- Blue cheese or another salty, pungent cheese.
- Fresh fruit, especially peaches, pears, or apples.
- Fruit tarts and lightly sweet desserts.
- Foie gras or other rich, savory foods, where available.
- Dark chocolate, if the wine has enough intensity to stand up to it.
A useful rule is to keep the dessert no sweeter than the wine. If the food is much sweeter, the wine may taste sharper or less expressive by comparison. For a simple pairing, try a small pour with a mild cheese or fresh fruit before serving it with a rich dessert.
Storage and how long an opened bottle lasts
Store an unopened bottle in a cool, dark place with a stable temperature. Avoid a sunny windowsill, a warm kitchen shelf, or a spot beside an oven, since heat and light can damage wine. If the bottle has a cork, follow normal wine-storage guidance for its closure and the producer’s instructions.
After opening, close the bottle securely and refrigerate it. Sweet wines can often remain enjoyable longer than many dry wines, but the exact period depends on the wine and storage conditions. Check its aroma and taste before pouring another glass; discard it if it smells or tastes unpleasant. A smaller pour also helps you avoid leaving a bottle open longer than necessary.
Do not freeze a finished bottle to make it “more like” ice wine. Freezing wine at home does not recreate the vineyard process, and expansion can push out a cork or damage the bottle. Chill it in the refrigerator instead.
Common misunderstandings about frozen-grape wine
“Any sweet wine made in a cold place is ice wine.”
No. Sweetness and a cold climate do not define the method. True ice wine is made from grapes that freeze naturally on the vine and are pressed while frozen, subject to the rules that apply where it is produced.
“The grapes are picked frozen and then thawed before pressing.”
That would defeat the concentration step. In the traditional method, grapes are pressed while frozen so ice remains behind and the concentrated juice can be collected. The timing matters as much as the temperature.
“Ice wine is always made from one grape.”
No single variety is required everywhere. Riesling and Vidal are well-known examples, but other grapes may be used. The label tells you which grape or blend is in the bottle.
“The sweeter the wine, the better the ice wine.”
Sweetness alone is not a quality measure. Balance matters: acidity, fruit, aroma, and finish should work with the sugar. Choose a style you enjoy rather than judging a bottle by sweetness alone.
“Freezing table grapes at home makes the same thing.”
It does not. A home freezer can freeze grapes, but it cannot reproduce the full process or turn them into ice wine without fermentation and appropriate winemaking. It also does not change how a commercial wine may legally be labeled.
How to tell what the label means
Wine terms can vary by country, so pay attention to both the name and the origin. Producers and wine regions may set requirements for how grapes are grown, frozen, harvested, and pressed before using a protected term. A bottle labeled “ice wine” may follow a different set of rules from one labeled “Icewine” or “Eiswein.”
If you want the traditional naturally frozen style, look for a clear description that says the grapes froze on the vine and were harvested and pressed while frozen. If the label only says that grapes were frozen, ask whether they froze before or after picking. That simple question clears up the most common source of confusion.
For a first bottle, pick a grape and flavor description that appeal to you, then serve a small chilled pour with fruit, cheese, or a lightly sweet dessert. The production method explains the wine’s identity; the balance of sweetness and acidity is what makes it enjoyable in the glass.
The wine made from grapes naturally frozen on the vine is called ice wine, Eiswein, or Icewine, depending on the region and label. Its concentrated sweetness is balanced by acidity, and its flavor depends on the grape and growing conditions.
For your first bottle, check that the grapes froze on the vine, choose a grape style you like, and serve a small chilled pour with fruit or cheese. That gives you a clear sense of the wine without confusing it with late-harvest or artificially frozen-grape styles.
