Acidity is a wine's “pucker” or tartness; it's what makes a wine refreshing and your tongue salivate and want another sip. ... When someone says a wine is crisp, bright or fresh, what they are really saying is the wine has great acidity, just as they would say that a citrus drink tasted fresh and bright.
or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine-making stretches over millennia. The science of wine and winemaking is known as oenology. A winemaker may also be called a vintner. The growing of grapes is viticulture and there are many varieties of grapes.
Winemaking can be divided into two general categories: still wine production (without carbonation) and sparkling wine production (with carbonation – natural or injected). Red wine, white wine, and rosé are the other main categories. Although most wine is made from grapes, it may also be made from other plants. (See fruit wine.) Other similar light alcoholic drinks (as opposed to beer or spirits) include mead, made by fermenting honey and water, and kumis, made of fermented mare's milk.
