What makes red wine red?
Red wine gets its color from the skins of red grapes (like white grapes, the flesh of red grapes is greenish, with one or two rare exceptions). As with white wines, grapes are harvested and crushed, but then the winemaker allows the grape juice to ferment in contact with the skins for days or even weeks, drawing out the polyphenols and tannins that produce color and structure. Then, also unlike most whites, red wines are usually aged for a year or two before being bottled (classically in oak barrels) to soften their roughness and astringency.
What makes red wine healthy?
There’s strong evidence that drinking red wine in moderation is good for your health. Researchers have suggested for years that the antioxidants found in red wines may help reduce the risk of heart disease. More recently, scientists have linked the specific antioxidant resveratrol to the formation of nerve cells, which may be useful in preventing Alzheimer’s and Parkinson’s. There’s even some tentative evidence that, thanks to resveratrol’s benefits, red wine may prolong life.
