Excerpt:

Alameda’s Rock Wall Wine Company and winemaker Shauna Rosenblum announced Wednesday that her father, legendary East Bay winemaker and “King of Zin” Kent Rosenblum died last night. He was 74.

Rosenblum was a veterinarian with a passion for winemaking, when he founded Rosenblum Cellars in West Oakland. It was 1978 and the concept of an urban winery was novel, but he wasn’t finding the idea of commuting between a winery in the country and his local veterinary practice particularly attractive. By 2008, when he sold what had become an Alameda winery to drinks company Diageo, production had reached 250,000 cases a year.

Like many winemakers, Rosenblum didn’t exactly retire. Instead, he opened a new winery, this time with his daughter Shauna. Rock Wall Wine Company sits in a cozy building next to an old aircraft hangar at the former Alameda Naval Air Station. ·
