[Gavril]

Kosher alcohol is made from crops (or whatever the particular alcohol is made from) that has been harvested by faithful Jewish males, and grown on a field that has been subject to Kosher rules for four years, i.e. only one type of crops per field, the field is left fallow every seventh year, etc., and a certain amount of the alcohol is spilled on the ground as a sacrifice to the Temple in Jerusalem. There are probably more rules than that, but that's what I could remember.
