Ice Wine (Eiswein): A Frozen Treasure of Sweetness

Ice wine (or Eiswein, as it's called in Germany) is a luxury dessert wine made from grapes that have naturally frozen on the vine. This unique and labor-intensive winemaking technique results in an intensely sweet wine with complex, concentrated flavors. Ice wine is celebrated for its honeyed, fruity, and aromatic qualities and is often seen as a special treat for dessert pairings or sipping after a meal.

How Ice Wine (Eiswein) Is Made

1. Harvesting at the Right Time – The grapes for Ice Wine are harvested only after the first frost of the season, usually in late fall or early winter. Grapes must remain on the vine until they freeze, which typically happens when temperatures drop to about -8°C (17.6°F) or lower. This is often the most critical stage of the process, as the timing must be perfect to ensure the grapes are frozen but still intact.
2. Frozen Grapes – Once the grapes freeze, their water content solidifies into ice. This leaves behind the concentrated sugars, acids, and flavors. Only the frozen grapes are used, and the rest of the fruit is left on the vine.
   Pressing the Frozen Grapes – The frozen grapes are carefully pressed while still frozen. Because the water in the grapes is solid, the juice that comes out is highly concentrated, resulting in a small yield of wine. This is why Ice Wine is often produced in small batches and can be quite expensive.
3. Fermentation – The concentrated juice undergoes fermentation, which can be slow due to the high sugar content of the grapes. The winemaker often stops fermentation early to leave some residual sugar, ensuring that the wine remains sweet and full-bodied.
4. Aging – After fermentation, Ice Wine is usually aged for a period of time to allow the flavors to develop and integrate. It is typically aged in stainless steel to preserve the fresh, fruity character, although some versions may see time in oak barrels to add more complexity
