The best temperature to serve Marlborough Sauvignon Blanc is between 45-50°F (7-10°C). Serving the wine at this cool temperature helps to accentuate its refreshing acidity and vibrant fruit flavors while preserving its delicate aromatics. To achieve this temperature, you can chill the wine in the refrigerator for about 2-3 hours before serving or place it in an ice bucket with a mixture of ice and water for about 20-30 minutes. Remember to monitor the wine's temperature and avoid over-chilling, as this can mute the flavors and aromas, diminishing the overall tasting experience.
