סתם יינם. If not for the foresight of Khaza"l in drying up the vintners lubricants of the gears of social interaction that culminate in Jewish sons marrying gentile daughters there would be no such thing as non-kosher wine and no need for kosher wine (except, perhaps, kosher l'Pesakh wine).
I wonder which social scientist could have predicted that just as snobbish kosher connoisseurs are developing a taste for flash-pasteurized cabs and Merlots , non-Jewish hip-hop artists have made sweetish Bartenura Moscato d'Asti (rated number 1 by Moscato Mom) their beverage of choice.
As reported today in an NYC tabloid "Bartenura, selling for about $15, is a kosher version in a deep blue
bottle. It’s expected to sell 400,000 cases this year, a record for any
kosher wine. According to Nathan Herzog of brand owner Royal Wine,
85 percent of Bartenura buyers don’t know or care that it’s kosher, or
that it’s named for a 15th-century Italian rabbi. They just know what they like."
