Final answer:
The recommended temperature range for most dessert and sparkling wines is -15 to 10 °C (5-50 °F), which helps to preserve their delicate flavors and sparkling characteristics.
Step-by-step explanation:
The temperature range for most dessert and sparkling wines is typically lower to preserve the delicate flavors and carbonation in sparkling wines. Dessert wines, often having a high sugar concentration, are well-preserved at cooler temperatures. Sparkling wines, which can contain pH 3 or below, should be kept chilled to protect their crispness and effervescence.
A typical serving temperature for these types of wine is often suggested to be within the range of -15 to 10 °C (5-50 °F). Storing wines at this temperature before serving helps to maintain their quality and sensory characteristics. It's crucial for the preservation of flavors that sparkling and dessert wines are kept within this recommended temperature range, differing from temperatures used for cooking, such as the 500°F setting used for broiling in many kitchen ovens.
