I want to make saba and savor, so I am wondering where I can buy grape must here in the Bay Area. I am also willing to crush the grapes myself. I guess that it should not be hard to find grapes (sangiovese?) with all the people that are making their own wine these days. I remember seeing bottles of grape juice sold at Village Market in the Ferry Building, however,
I suspect that they add something to the grapes to prevent fermentation.
