Which type of wine is produced from grapes that are frozen while still on the vine?

The type of wine produced from grapes that are frozen while still on the vine is ice wine. This unique winemaking process involves allowing the grapes, typically varieties like Riesling or Vidal Blanc, to remain on the vine until they freeze, usually at temperatures around -8°C (17.6°F) or lower. When harvested, these frozen grapes are pressed, and because the water content remains frozen, the resulting juice is highly concentrated in sugars, acidity, and flavor. This leads to a sweet wine with intense flavors and a rich mouthfeel.

The other options do not involve this specific freezing process. Dry white wine can be made from various grape varieties but does not utilize frozen grapes. Red wine is produced from dark-skinned grape varieties and typically emphasizes fermentation processes that extract color and tannins rather than relying on the grapes being frozen. Rosé wine involves the skin contact from red grapes for a limited time to achieve a pink hue but, again, does not utilize freezing as part of its production method. These distinctions highlight why ice wine is the correct answer in this context.
