Owner Jeff Cohn of JC Cellars has always been interested in the world of wine, but it wasn't until he tasted a Chateauneuf-du-Pape that the cosmos unfurled before him. "To go from tasting only single varietals to a blend really opened my eyes," he wrote in his bio. He started crafting his own wines and tinkering with production methods, experimenting with different yeast strains. Cohn eventually produced the 2003 Rhodes Vineyard Zinfandel, which was named number three on Wine Spectator's Top 100 List—the first time a California Zinfandel had even been in the top 10.
Now, Cohn curates a roster of 21 vintages based on Rhone grape varietals at JC Cellars. The wines are the product of both his own production techniques and time-tested French methods. Visitors to the cellars can gaze upon the aging barrels during tastings led by seasoned wine educators, before taking a bottle home to christen a life-size replica of the Millennium Falcon.
Though wine has been made for centuries, a lot has changed since the early days. Now, additives and preservatives are blended into many wines, often affecting the taste and smell along the way. Fortunately, that’s not the way they do things at Fat Grape Winery. There, all wines are made the old-fashioned way. Helmed by winemaker Patrick Bowen, the winery creates more than a dozen wines—each made from Californian grapes—at their facility on Treasure Island's old Navy Brig. There, visitors can stop by to sample any of the wines—which they even have fresh on tap— or purchase bottles to take home.
Alameda Naval Air Base's Building 24 once housed the latest fighter craft, ready to leap over the stone tidal wall to the south and enter World War II's Pacific Theater. Now the facility's vast, climate controlled interior serves a gentler purpose. It hosts the father and daughter winemaking team, founders and industry veterans Kent and Shauna Rosenblum, who draw grapes from all of California's richest soils to mix and ferment them on San Francisco's doorstep. Taking inspiration from the harbor fortifications still visible in the surf, they call themselves Rock Wall Wine Company.
They put the full 40,000 square feet of the former hangar to use, fermenting grapes in the cellar, loading and draining barrels, and hosting events to show off their collection of more than 30 wines. When they roll up the doors, views extend to the San Francisco skyline, a sunny vision which pairs nicely with Cabernet Sauvignon grown in Napa Valley or Zinfandel harvested in Contra Costa County. The combinations of grapes from all over the state have won a steady stream of awards.
