What are typical fermentation temperatures for white wines and the styles they produce?

• A. ~10C: very crisp, light-bodied wines
• B. ~12-14C: moderate aromatic profile
• C. ~15C: fruity/aromatic wines
• D. ~25C: very full-bodied, less fruity

Answer: (C)

Fermentation temperature shapes the aroma and feel of white wines by controlling which volatile compounds are formed. Cooler temps slow aroma development and help preserve crisp acidity, while warmer temps increase ester production that boosts fruity and floral notes but can soften brightness and raise body.

Around 15°C hits a balance that many white wines use to maximize fruity and aromatic character while keeping the wine fresh and lively. At about 10°C, you’d tend to get a crisper, lighter profile with less pronounced aroma. At 12–14°C you’d see cleaner aromatics but not as pronounced as at 15°C. At ~25°C fermentation, the wine can become fuller-bodied with more pressure from extraction and higher alcohols, often at the expense of delicate fruit aromas.

So the best match for typical white styles that are fruity and aromatic is around 15°C.
