维基百科，自由的百科全书
葡萄汁是由葡萄果肉榨出的果汁。它经常用来发酵后制取葡萄酒，白兰地或者威士忌。在酿酒工业中，葡萄汁是一种必需的产品。葡萄汁有时候也加糖，作为一种不含酒精的饮料。保存葡萄汁需要使用巴氏消毒法，因为未经处理的果汁中往往自然含有葡萄上的酵母会自然发酵。

[编辑] Welch's Grape Juice
The method of pasteurizing grape juice to halt the fermentation has been attributed to an American physician and dentist, Thomas Bramwell Welch in 1869. A strong supporter of the temperance movement, he produced a non-alcoholic wine to be used for church services in his hometown of Vineland, New Jersey. His fellow parishioners continued to prefer and use regular wine.
His son Charles E. Welch, also a dentist, eventually gave up his practice to promote grape juice, founding Welch's Grape Juice Company. The product was given to visitors at international exhibitions. The company supplied "grapelade" to the military during World War I and advertised aggressively. Development of new grape products and sponsorship of radio and television programs eventually made the company very successful.
