Historically, kosher wine has been associated in the US with the Manischewitz brand, which produce a sweetened wine with a distinctive taste, made of labrusca rather than vitis vinifera grapes. Due to the addition of high-fructose corn syrup, the normal bottlings of Manischewitz are, for Ashkenazi Jews, not kosher during Passover by the rule of kitniyot, and a special bottling is made available. This cultural preference for a distinct, unique variety of wine dates back to Jewish settlements in early US history.[11]
