Which of the following wines requires a lower serving temperature?

Sparkling wine is best served at a lower temperature, typically between 6°C to 10°C (43°F to 50°F). Serving sparkling wine at this temperature enhances its refreshing qualities and preserves the crispness and effervescence that are characteristic of this style.

In contrast, full-bodied red wines, medium-bodied white wines, and sweet wines are generally served at slightly higher temperatures. Full-bodied reds are often enjoyed at room temperature or slightly below, as warmth helps to express their rich flavors and aromas. Medium-bodied whites, like Chardonnay, are best served chilled but slightly warmer than sparkling wines, usually around 10°C to 13°C (50°F to 55°F). Sweet wines can vary depending on their style, but they are often served chilled as well, typically around 7°C to 12°C (45°F to 54°F), to balance their sweetness with acidity. This serves to enhance the wine's complexity without overwhelming the palate. Thus, sparkling wine stands out as the one that benefits most from a lower serving temperature, making it the correct choice in this scenario.
