Does the amount of rainfall prior to harvest impact the flavor?

Yes No Only affects color Only affects acidity

Correct Answer:

Yes

Explanation:

Rainfall before harvest changes how grapes ripen and what ends up in the wine, which in turn shapes flavor. Water availability affects berry size and the concentration of sugars, acids, and flavor compounds. If a lot of rain occurs close to harvest, berries can swell and dilute sugars and acids, potentially softening flavor intensity. Rain also influences the development of aroma precursors and polyphenolics that contribute to aroma, mouthfeel, and aftertaste. In drier periods or with rain earlier in the season, flavors and aromas can become more concentrated. Since wine flavor comes from a balance of sugars, acidity, phenolics, and aromatic compounds, the amount and timing of rainfall prior to harvest does matter for flavor.
