So you found a terrific wine and want to tell your friends. Sweetness is the most familiar of these three taste components.
Acidity can hide sweetness.
For example, acidity dominates the sugars in green apples, so they taste tart or crisp. But as apples ripen, their sugar content increases. At first they balance, then they mask acidity. To sample sweetness in wines, try some rieslings from California. For acidity, try some white wines from Washington.
