Kosher wine () is wine that is produced in accordance with halakha, and more specifically kashrut, such that Jews will be permitted to pronounce blessings over and drink it. This is an important issue, since wine is used in several Jewish ceremonies, especially those of Kiddush.
To be considered kosher, Sabbath-observant Jews must supervise the entire winemaking process and handle much of it in person, from the time the grapes are loaded into the crusher until the finished wine product is bottled and sealed. Additionally, any ingredients used, including finings, must be kosher. Wine that is described as "kosher for Passover" must have been kept free from contact with leavened or fermented grain products, a category that includes many industrial additives and agents.
When kosher wine is produced, marketed, and sold commercially, it would normally have a hechsher (kosher certification mark) issued by a kosher certification agency, or by an authoritative rabbi who is respected and known to be learned in Jewish law, or by the Kashruth Committee working under a beth din (rabbinical court of Judaism).
In recent times, there has been an increased demand for kosher wines, and a number of wine-producing countries now produce a wide variety of sophisticated kosher wines under strict rabbinical supervision, particularly in Israel, the United States, France, Germany, Italy, South Africa, Chile, and Australia. Two of the world's largest producers and importers of kosher wines—Kedem and Manischewitz—are both based in the American Northeast.
Alcohol in the Bible
The use of wine has a long history in Judaism, dating back to biblical times. Archeological evidence shows that wine was produced throughout ancient Israel. The traditional and religious use of wine continued within the Jewish diaspora community. In the United States, kosher wines came to be associated with sweet Concord wines produced by wineries founded by Jewish immigrants to New York.
Beginning in the 1980s, a trend towards producing dry, premium-quality kosher wines began with the revival of the Israeli wine industry.
