Canadian icewine is what happens when a grower looks out at a vineyard in January, sees the grapes hanging solid with frost, and decides that’s exactly the moment to pick. It’s a sweet wine pressed from grapes frozen naturally on the vine — the water stays behind as ice in the press, and what drips out is thick, intensely sweet, and startlingly high in acid. Canada makes more of it than anywhere on earth, mostly around Ontario’s Niagara Peninsula. By the end of this you’ll know what separates a decent bottle from a proper one, why the price doesn’t apologise for itself, and how to serve the little you need of it well.
What is Canadian icewine?
Canadian icewine is a sweet wine made exclusively from grapes left on the vine until natural cold — at least −8°C — freezes the water inside the berry solid. Growers then harvest and press while everything’s still frozen, so the ice stays behind and only a concentrated syrup of juice runs out. It’s a protected, trademarked term: since 2014, only wine made this way, in Canada, can be called Icewine.
Most of it comes from Ontario, with smaller amounts from British Columbia, Quebec and Nova Scotia. Under the VQA rules that govern Ontario and BC, that −8°C threshold is stricter than Germany’s, where Eiswein can be picked at −7°C. Pickers work through the night, by hand or increasingly by machine, because that’s when the temperature actually holds. Pressing can take upward of twelve hours, and it happens outdoors, in the cold, before anything thaws.
What is special about icewine?
What makes it different isn’t just the sweetness — it’s how nature does the work. The grapes must be healthy, not botrytis-affected like Sauternes (see our Sauternes guide if you want the noble-rot version of sweet), and freezing must happen on the vine, in the open air. Freeze it artificially in a cold room instead, and the wine can’t legally use the name Icewine at all — that’s cryoextraction, a cheaper, less risky shortcut, and it’s a different product by law.
The freeze-thaw cycles themselves matter. Trade opinion holds that repeated freezing and thawing through the winter builds the character that defines the style — concentrated pear, apricot and apple fruit, sometimes verging on honeyed. Sugar levels get so high that fermentation usually gives up on its own, somewhere around 9-11% alcohol, leaving 200-250 grams of residual sugar per litre still in the glass. Most is fermented and aged in stainless steel to keep that pure fruit character; some producers use oak for a touch of vanilla and clove, but it’s the exception rather than the rule.
Choosing a bottle: grape matters more than the label suggests
Two grapes dominate, and they don’t taste alike. Vidal, a hardy French hybrid originally bred for cognac production, has a thick skin that shrugs off Canada’s brutal winters — it’s the workhorse of the category, giving riper, more overtly honeyed wines. Riesling, thinner-skinned and pickier about conditions, tends to produce the most complex and well-balanced examples, with the acid to carry real age.
Beyond those two, you’ll find Cabernet Franc (for a rare red icewine), Gewürztraminer — worth a look if you already like its aromatic, floral style, and we cover that ground properly in our Gewürztraminer guide — and occasionally Chardonnay. A handful of producers also make a sparkling version, which is a genuine oddity worth trying once.
| Grape | Character | Good for |
|---|---|---|
| Vidal | Riper, honeyed, thick-skinned, forgiving of harsh winters | An easy, generous first bottle |
| Riesling | High acid, more structured, ages well | Anyone who likes tension in a sweet wine |
| Cabernet Franc | Rare, red-fruited icewine | Curiosity and dinner-party talking points |
| Gewürztraminer | Aromatic, floral, less common | Fans of lychee and rose-petal whites |
What is the best Canadian ice wine?
There’s no single “best” — it depends on grape, region and what you want from the glass. Riesling icewine, mostly from Niagara, tends to give the most complex, age-worthy wines, with the acid to balance all that sugar for years. Vidal is the more forgiving, more widely planted grape, and gives a riper, rounder style that’s the friendlier entry point for a first bottle.
Region plays a part too. Niagara’s lake-effect climate — cold enough to freeze reliably, but moderated by Lake Ontario — is why Ontario dominates production. British Columbia’s Okanagan Valley makes it too, in smaller volumes, often with a slightly different fruit profile from its drier climate. Vintage matters more here than in most wine styles: a genuinely bitter winter (trade press has recorded harvests as early as mid-December in cold years, and as late as early January in milder ones) can mean a bumper crop one year and a nervous, thin one the next.
Why is icewine so expensive?
Icewine costs what it costs because so little of the harvest survives to become wine. Yields can run as low as 10% of a normal grape harvest — the berries dehydrate on the vine, and a good number are lost outright to rot, birds, or a January thaw that arrives before the temperature ever drops far enough. Everything that follows, from night-time hand-picking to slow, cold pressing, adds cost on top of a crop that was already scarce.
The numbers bear this out. Trade coverage of Canada’s 2021 export figures put Icewine at around 15% of bottled wine exports by volume — but 61% by value. That’s the whole story of the category in two figures: rare, and priced like it. It’s also why, if you’re trying to buy Canadian icewine UK-side, you’ll find the selection thinner than you’d expect for a wine this well known — most of what’s made gets snapped up by export markets in Asia and the US before it ever reaches a British shelf.
Serving it properly
Pour it cold and pour it small — this is a wine built for a thimble, not a tumbler. Half bottles are the standard format for good reason: at this price and this sweetness, nobody’s getting through a full 750ml in one sitting, so if you’re planning to buy Canadian icewine in the UK, start there rather than the full-size bottle.
On food, trade convention is more useful for what to avoid than what to chase: goat’s cheese and rich chocolate desserts tend to fight the wine rather than flatter it, the acidity and sweetness pulling in different directions. Simpler is better — on its own, after dinner, is often the right call.
If cold-climate sweetness isn’t quite your thing, the southern hemisphere handles dessert wine rather differently — worth a look in our Australia and New Zealand guide. And if you want the fuller picture of where Canada sits among the Americas’ wine regions, our pillar guide to New World wine covers the whole continent.
Questions customers ask us
Is Canadian icewine the same as German Eiswein? Same idea, different rulebook. Germany’s Eiswein needs grapes picked below −7°C and got its own Prädikat category in 1982; Canada’s threshold is colder, at −8°C, and permits Vidal, a grape not used in Germany’s system at all.
What’s the story with Inniskillin and Canadian icewine? Inniskillin is the Niagara name most credited with putting Canadian icewine on the world stage from the 1980s onward. These days dozens of wineries across Ontario and British Columbia make it just as well, so treat any one name as a starting point, not the final word.
Can I get Canadian icewine delivered in the UK? Yes, though stock is genuinely limited — low yields and strong export demand elsewhere mean decent Canadian icewine UK availability is patchy. Ordering ahead of Christmas, rather than browsing on a whim, tends to work better.
The merchant’s last word
I’ve poured icewine for customers who expected a novelty and left with a bottle they talked about for months — it does that. It’s not a wine you drink often, and it shouldn’t be; it’s one you keep for the right small glass, the right cold night. If that sounds like your kind of thing, browse the United States cellar and see what’s in.
