Excerpt:

Along with her father, the 20-something winemaker opened Rock Wall Wine Company, also Alameda-based, in 2008 (Shauna serves as Rock Wall's winemaker, her father is consulting winemaker). The wines are solid and come with a hefty dose of that big, jammy signature Rosenblum style, but what's most compelling here is the share-and-share alike winemaking mentality.

The Rosenblums operate Rock Wall Wine out of a 40,000 square foot airport hanger on a former Naval Air Base -- more than enough room for a small winery. And so they rent out the space, and share equipment, with a half dozen other small wineries, including Blacksmith Cellars, Carica Wines, Ehrenberg Cellars, R&B Cellars, John Robert Eppler Wines, and Virgo Cellars. There's a new tasting room, too.

It's a smart business plan to share the rent, no doubt. But it also means that small wineries without the investment heft that the Rosenblums bring to the financial table can focus on wine production without shelling out the big bucks for their own facility.
