How grapes evaporated?

Answer 1

Grapes themselves do not evaporate, but the moisture within them can evaporate under certain conditions, such as heat or low humidity. This process occurs when water molecules within the grapes transition from a liquid state to a vapor, often leading to drying out the fruit. In winemaking, this concept is utilized in techniques like appassimento, where grapes are dried to concentrate their sugars and flavors before fermentation. Thus, the evaporation of moisture from grapes is a crucial aspect in both culinary and fermentation processes.
