Wine is an alcoholic beverage made by fermenting crushed grapes or other fruits, with its origin tracing back thousands of years to ancient civilizations in the Caucasus and Middle East. The primary ingredients are fruit juice, yeast, and often added sulfites for preservation. Its character varies immensely based on grape variety, terroir, and winemaking techniques.
Wine is very low in fat and protein, with its calories coming almost entirely from alcohol and residual sugars, providing roughly 120-130 calories per 5-ounce (150ml) serving. It contains minimal key nutrients, though it can offer small amounts of antioxidants like resveratrol, particularly in red varieties.
Culturally, wine has been intertwined with religion, trade, and social rituals for millennia, from ancient Dionysian festivals to its central role in Christian sacraments. Nutritionally, its most unique aspect is the presence of polyphenolic compounds from grape skins, which are studied for potential antioxidant properties.
