The Barrel Room Wine Tasting Classes

Wine is an alcoholic drink typically made from fermented grapes. 

Yeast consumes the sugar in the grapes and converts it to ethanol, carbon dioxide, and heat. Different varieties of grapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes involve fermentation of additional crops including, rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry.

Wine has been produced for thousands of years. The earliest evidence of wine is from Georgia (6000 BC),[1][2][3] Iran (5000 BC),[4] and Sicily (4000 BC).[5] In modern times, the five countries with the largest wine-producing regions are in Italy, Spain, France, the United States, and China.[6]

Wine has long played an important role in religion. Red wine was associated with blood by the ancient Egyptians[7] and was used by both the Greek cult of Dionysus and the Romans in their Bacchanalia; Judaism also incorporates it in the Kiddush and Christianity in the Eucharist.
