Additionally, as R. Haym Soloveitchik has pointed out (in his essay "Can Halakhic Texts Talk History?" [AJS Review 1978] and in his book Stam Yeinam, neither of which I have in front of me to give an exact citation or quote), there is no evidence that Rashi was a winemaker. Everyone in that time and place made their own wine. Could Rashi have been a winemaker? Yes, but for all we know he could also have been an egg salesman.
