Ice Wine (Eiswein)

An intensely sweet wine pressed from grapes frozen solid on the vine, concentrating pure, vivid, high-acid juice.

What makes Ice Wine (Eiswein) distinctive

The grapes freeze on the vine and are pressed while still frozen, so the water stays behind as ice and only a tiny drop of super-concentrated, sugar-and-acid-packed juice comes out. The result is pure, vivid and electric rather than heavy.

Why it matters

Ice wine — Eiswein in German — is one of the wine world’s great high-wire acts: a rare, intensely sweet wine made only when nature cooperates and growers gamble on a hard winter freeze.

The idea is simple but daring. Healthy grapes are left hanging long after the normal harvest, deep into winter, until a sharp frost freezes them solid on the vine. They’re then picked and pressed while still frozen.

It matters because it shows, more vividly than almost any other wine, what concentration really means. There’s no added sugar and no fungus involved — just water removed as ice, leaving a tiny amount of dazzlingly pure, sweet-and-tart juice. For a beginner it’s the perfect lesson in how sweetness and acidity can balance into something thrilling rather than sticky.

What’s in the glass

Expect a small pour of golden, syrupy-looking wine that is lusciously sweet yet, crucially, mouth-wateringly fresh.

The taste — what to look for: • Vivid lime and green apple • Ripe apricot and peach • Honey and candied citrus peel • Often a tropical lick of mango or pineapple

Riesling versions lean zesty and citrussy; Vidal versions lean riper and more tropical.

Body & texture: medium to full and viscous on the palate (it coats the glass), but never heavy — because the acidity is searingly high.

The magic balance: that electric acidity is what saves ice wine from being cloying. Sweetness this intense would feel like syrup without an equally intense streak of tartness pulling against it. There’s no tannin and no oak getting in the way — just pure, glassy fruit.

Where it comes from

Two countries lead, and the climate explains why.

Germany (the birthplace): The style was discovered here in the late 1700s, and the classic homes are the Mosel, Rheingau, Pfalz and Rheinhessen, almost always from Riesling. German Eiswein sits at the very top of the country’s official ripeness ladder, the Prädikat system — the grapes must be naturally frozen at −7°C or colder, never artificially chilled, by law.

Canada (the modern powerhouse): Chillier and more reliable, Ontario (especially the Niagara Peninsula) and British Columbia make more ice wine than all other countries combined, often from the hardy Vidal grape as well as Riesling. Canadian ‘Icewine’ is a legally protected term, with the grapes required to freeze on the vine at −8°C or colder.

You’ll also find occasional bottles from Austria and elsewhere, sometimes from red grapes like Cabernet Franc. Look for the words Eiswein or Icewine on the label — they’re protected and mean the real, frozen-on-the-vine thing.

What shapes it — the freeze, not the rot

The defining technique: grapes are left on the vine into deep winter and only picked once a natural frost (around −7°C in Germany, −8°C in Canada, or colder) freezes the water inside each berry into ice crystals. They’re rushed to the press still frozen, so the ice stays behind in the press and only a few drops of concentrated, sugary, high-acid juice trickle out. Yields are tiny — a vine that might make a bottle of normal wine yields a thimble of ice wine — which is why it’s expensive.

The two key grapes: • Riesling brings naturally high acidity and keeps its freshness hanging late into the season • Vidal (a tough hybrid grape) has thick skins that survive months on the vine and resist rot — ideal for cold Canada

The key myth-buster: ice wine is not made by ‘noble rot’. Sweet wines like Sauternes and Tokaji rely on a benevolent fungus (botrytis) that shrivels the grapes. Ice wine concentrates sugar purely by freezing — the grapes should ideally stay clean and healthy. That’s why ice wine tastes so clean and vivid, while botrytis wines taste more honeyed and ‘mushroomy’-complex.

Good to know

Food — what works: • Fresh fruit and not-too-sweet desserts — apple or apricot tart, lemon posset, panna cotta • A classic trick: serve it against rich, salty things like foie gras or a sharp blue cheese, where sweet-meets-savoury sparks fly • Avoid pairing with desserts sweeter than the wine, which flattens it

Serve & store: chill it well (6-8°C) and pour small — it’s potent. A half-bottle (375ml) goes a long way and is the usual format. Opened, it keeps in the fridge for a week or more thanks to all that sugar and acid.

Ageing: the high acidity means good examples, especially Riesling, can age for a decade or far longer, deepening toward toffee, marmalade and dried apricot.

Common confusions: • Don’t confuse it with Late Harvest wine (picked riper but not frozen) • Don’t assume all dessert wine is botrytised • Beware cheap ‘iced’ or ‘cryo-extracted’ wines made by freezing grapes in a freezer after picking — true Eiswein/Icewine must freeze on the vine, and the protected names guarantee it
