The ideal wine serving temperature
The serving temperature of wine can amplify good or bad elements in wine. In general white wine and rosé are served much cooler then red wine.
The golden rule with wine is to avoid extreme temperatures. In other words, don’t serve red wine to warm and white wine too cool. However, when in doubt it is always better to serve a wine a bit too cold instead of too warm. The wine will warm up in the glass.
A low temperature will emphasize the tannin. That’s why it is recommended to keep wines with a lot of tannin fairly warm. However, when the temperature of a red wine reaches over 20°C the alcohol begins to evaporate and sting unpleasantly. When a white wine is chilled below 8°C it loses its aroma.
