Growing Icewine Grapes in Canada
Which cold-hardy grapes survive the long winter hang on the vine, picked by zone — and why keeping the vine alive through a Canadian winter is the real challenge.
Updated July 2026 · Cold-hardy grape data + VQA icewine rules
The grapes behind Canada's world-beating icewine aren't exotic — several are tough French and Minnesota hybrids you can plant in a backyard from Ontario to the Prairies. Growing them is well within reach.
This guide covers variety selection through the icewine lens — which grapes actually survive hanging on the vine into deep winter — and how to keep the vines alive until the freeze comes.
Growing icewine grapes in Canada: plant a hardy, thick-skinned variety that can hang into deep winter — Vidal is the benchmark (Zone 4), with Frontenac, Marquette, and La Crescent for colder Prairie gardens (Zone 3 with cane burial) and Riesling in milder Zone 5b+ sites. Keeping the vine alive through winter is the real challenge; true icewine is made only from grapes frozen naturally on the vine and harvested at −8 °C.

Best Grapes for Icewine & Winter Wine by Zone
The icewine lens changes how you pick a variety: on top of ordinary hardiness, the grape must have a thick skin and good disease resistance so the fruit stays intact through the long hang. Thin-skinned table grapes drop or rot before the freeze ever arrives.
| Variety | Vine hardy to | Why it suits icewine / winter wine |
|---|---|---|
| Vidal | Zone 4 | The benchmark. A thick-skinned French hybrid that hangs into deep winter without splitting — the grape behind most Canadian icewine. Honey and tropical fruit. |
| Riesling | Zone 5b | Makes the finest, most age-worthy icewine, but less hardy — give it a sheltered, milder site. The classic Germanic icewine grape. |
| Cabernet Franc | Zone 5b | The main red icewine grape — a striking pink-to-red dessert wine with rhubarb and red-fruit notes. Mild zones only. |
| Frontenac | Zone 3 | A University of Minnesota hybrid — the hardiest realistic option. Excellent for Prairie late-harvest and dessert wine; high sugar and acid. |
| Marquette | Zone 3 | Another hardy Minnesota red hybrid, disease-resistant and productive — a strong choice for cold-zone winter wine. |
| La Crescent | Zone 3 | A hardy white Minnesota hybrid with apricot and citrus notes — naturally high sugar, well suited to sweet late-harvest styles. |
The pattern: in Zone 5 and warmer, Vidal (and Riesling/Cabernet Franc in sheltered spots) are the true icewine grapes. In Zone 2b–4, the Minnesota hybrids are the hardy realists — and a true −8 °C freeze on the vine is a bonus of the same cold climate. For the full planting, pruning, and trellising method for any of these, see Growing Grapes in Canada.
Growing the Vines — Winter Survival Is the Real Challenge
Keeping the vine alive through a Canadian winter is a bigger hurdle than the harvest freeze. Two things matter most:
- Cane burial in Zone 2b–4. Prairie and cold-zone growers lay the canes down in late October and cover them with soil, mulch, or snow, then uncover and re-tie them in April. It's the standard technique that lets tender-to-borderline vines survive where they'd otherwise winterkill.
- The long hang means the vine must be healthy and well-fed all season so the fruit ripens fully before the killing frost — because after that, the grapes only dehydrate and concentrate; they don't ripen further. In short-season cold zones, full ripening is the true limiting factor, not the winter freeze.
And through it all: net the vines. From before the first frost until you harvest, bird netting is the difference between a crop and an empty trellis.

Frequently Asked Questions
Can you grow icewine grapes at home in Canada?
Yes — you can grow the vines. The cold-hardy grapes behind Canadian icewine, led by Vidal, survive to Zone 4 (and Prairie hybrids like Frontenac and Marquette to Zone 3 with winter protection), so they are very much a home-garden option across most of settled Canada.
What is the best grape variety for icewine in Canada?
Vidal is the clear choice, and it dominates Canadian icewine for a reason: it's a hardy French hybrid (Zone 4) with a notably thick skin, which lets the fruit hang on the vine into December and January without splitting or rotting — exactly what the long wait for a -8°C freeze demands. Riesling makes a finer, more age-worthy icewine but is less hardy (best Zone 5b+) and needs a sheltered site. Cabernet Franc is used for red icewine in mild zones. For colder Prairie gardens, the University of Minnesota hybrids Frontenac, Marquette, and La Crescent are the hardiest options (Zone 3 with cane burial) and make excellent late-harvest and dessert wines even if a true -8°C icewine harvest is a stretch.
Which grapes survive the winter hang for icewine?
The key trait is skin thickness plus disease resistance, because the fruit must stay intact on the vine for two to three months past normal harvest. Vidal is the benchmark — its thick skin resists the splitting and rot that ruin thinner-skinned grapes over a long hang. Among the cold-hardy hybrids, Frontenac and its relatives hold up reasonably well; delicate thin-skinned varieties and most table grapes do not and will drop or rot before the icewine freeze arrives. This is why nearly all Canadian icewine starts with Vidal.
How cold-hardy do icewine grapes need to be?
Hardy enough to survive your winter as a living vine — which is a separate question from surviving the harvest freeze. The vine itself must come through the coldest part of winter alive: Vidal and Riesling are reliable to about Zone 4-5, while the Minnesota hybrids (Frontenac, Marquette, La Crescent) reach Zone 3, and Valiant and Beta go colder still. In Zone 2b-4, growers bury the canes under soil or mulch in late October and uncover them in April to get the vines through. The -8°C harvest freeze that makes the wine is a bonus of the same cold climate — the challenge is keeping the vine alive to reach it.
What is the difference between icewine and late-harvest wine?
True icewine requires the grapes to freeze naturally on the vine and be harvested at -8°C — the standard behind Canada's VQA icewine designation. Late-harvest wine takes the opposite, easier route: leave the grapes to shrivel and sweeten on the vine in autumn but pick them before any hard freeze. It's sweet and rich, if less intensely concentrated than icewine.
Do I need bird netting for icewine grapes?
Absolutely — bird protection is not optional for any icewine attempt. Because the fruit hangs for two to three months after every other grape and berry has been picked, it becomes the only sweet food left in the vineyard, and birds will strip an unprotected crop completely. Commercial growers net entire blocks. A home grower must net the vines securely from before the first frost right through to the winter harvest. Skipping this is the single fastest way to lose the whole crop.
Where can I grow icewine grapes in Canada?
Anywhere you can keep the hardy vines alive and get a reliable deep freeze — which is most of settled Canada outside the mild coast. The classic regions (Niagara, the Okanagan) pair a full ripening summer with a dependable -8°C winter. Colder zones on the Prairies and in Quebec can grow the hardiest hybrids with cane burial and get the freeze easily, though the shorter, cooler summer makes fully ripening the fruit the limiting factor. Mild coastal British Columbia (Vancouver, Victoria) is the one place that struggles: the vines grow fine, but the winters rarely reach a sustained -8°C, so a true icewine harvest almost never happens there.
