From Berkeley to Brooklyn, an estimated 200 urban wineries are operating in the United States. These include a combination of commercial wineries and DIY custom-crush facilities, where people with cash to drop make barrels of their own wine. But the nation's largest concentration of pure commercial urban wineries -- 23 -- is in the East Bay, where the movement began.
"That's definitely a trend that moved west to east," says wine educator Karen MacNeil, author of "The Wine Bible" (Workman, 2000).
