Marketing alcohol is especially difficult. For starters, its leading “attraction” (that alcohol causes your mind to stop functioning, in a pleasant way) can’t be touted as a feature (imagine an ad: drink my vodka, it will make you act like a fool or knock you out). For Jews its especially a problem since in our culture being intoxicated is viewed quite negatively. On top of that, most good wines are from countries that have a long history of anti-semitism (imagine an ad: buy Italian wine, from the country that destroyed the Beis ha-Mikdash, or perhaps a French wine putting Dreyfus on the label).
So when you come up an effective way of marketing alcohol, be sure to let them know.
