Overview & History
Ice wine (Eiswein in German, Icewine in Canada) is a rare and precious dessert wine made from grapes that have naturally frozen on the vine. When pressed while still frozen, these grapes yield a tiny amount of intensely concentrated, sweet juice that ferments into one of the world's most prized dessert wines.
The style originated in Franconia, Germany in 1794 when an early frost caught winemakers off guard. Rather than waste the frozen crop, they pressed the grapes anyway and discovered the remarkable concentration and purity of the resulting wine. Today, while Germany remains the spiritual home of Eiswein, Canada—particularly Ontario's Niagara Peninsula and British Columbia's Okanagan Valley—has become the world's largest and most consistent producer.

Styles & Grape Varieties
Vidal (Canada): The workhorse of Canadian ice wine. This French hybrid is thick-skinned and cold-resistant, producing rich wines with tropical fruit, honey, and marmalade notes. The most widely planted ice wine grape.
Riesling: Produces the most elegant, age-worthy ice wines with piercing acidity, citrus, stone fruit, and mineral notes. The traditional choice in Germany and gaining popularity in Canada.
Cabernet Franc: A Canadian specialty—red ice wine with concentrated flavors of strawberry, cherry, and spice. Rare and visually stunning with its deep ruby color.
Gewürztraminer: Exotic ice wines with intense lychee, rose petal, and spice aromatics. Particularly successful in Alsace and Canada.
Grüner Veltliner: An Austrian specialty producing ice wines with white pepper, citrus, and herbal notes alongside the characteristic sweetness.
Production Method
True ice wine production is a high-risk endeavor governed by strict regulations. In Canada (VQA) and Germany/Austria, grapes must freeze naturally on the vine to at least -8°C (17°F), though many producers wait for -10°C to -13°C for optimal concentration. Artificial freezing is prohibited for authentic ice wine.
Grapes are left hanging through autumn, protected from birds and rot with netting, while winemakers anxiously watch weather forecasts. When temperatures finally drop, often in the middle of a winter night (December through February), harvest teams rush out to pick and press the frozen grapes before they thaw. The water in the grapes remains as ice crystals in the press, while only the concentrated sugary liquid flows out.
Yields are minuscule—a vine that would normally produce a bottle of table wine may yield just a single glass of ice wine. Fermentation is extremely slow due to the high sugar content, often taking months, and may stop naturally before all sugar converts to alcohol, leaving intense residual sweetness balanced by bracing acidity.
Tasting Notes
- Vidal: Peach, mango, apricot, honey, orange marmalade, caramel
- Riesling: Green apple, lime, peach, petrol (with age), honey, jasmine
- Cabernet Franc: Strawberry, cherry, raspberry, spice, vanilla
- Gewürztraminer: Lychee, rose, ginger, honey, Turkish delight
The hallmark of quality ice wine is electric acidity that cuts through the sweetness, creating a fresh, vibrant finish rather than cloying heaviness.
Food Pairings
Fun Facts
- Canada produces more ice wine than the rest of the world combined. The Niagara Peninsula's consistent winters make it one of the only places where ice wine can be produced reliably every year—German Eiswein production varies wildly with unpredictable weather.
- It takes approximately 3.5 kilograms (8 pounds) of frozen grapes to produce a single 375ml bottle of ice wine, compared to just 1.2kg for regular wine. This scarcity is why genuine ice wine commands premium prices.
- Climate change poses an existential threat to traditional ice wine regions. Some German producers have gone years without being able to produce Eiswein as winters become milder and less predictable.
Serving Tips
Serve ice wine well-chilled (43-50°F) in small portions—a 2-3 ounce pour in a small tulip-shaped glass is ideal. The small glass concentrates the intense aromatics while the cold temperature keeps the sweetness refreshing. Allow the wine to warm slightly in the glass to fully appreciate its complexity.
Ice wine is best enjoyed as a dessert itself or with lighter desserts that won't overwhelm its delicate flavors. Avoid pairing with chocolate (too heavy) or anything sweeter than the wine itself. Once opened, ice wine keeps remarkably well—2-3 weeks refrigerated—thanks to its high sugar and acid content acting as natural preservatives.
