Rosenblum Cellars is a U.S. wine producer focused on Zinfandel, sourcing grapes from historic Northern California vineyards to capture the influence of soil, terrain, and old vines. Founded by Kent Rosenblum, the winery began in Alameda in 1978, emphasizing relationships with generations-old grape growers and bringing their fruit to a dockside facility to craft wines that reflect regional character. Its portfolio includes single-vineyard Zinfandels from Sonoma and Alexander Valley as well as carefully selected regional blends, with more than fifty Zinfandels earning 90+ points from Wine Spectator. Operating within the beverage manufacturing industry, the company is a small-to-mid-sized producer that relies on winemaking craft and long-standing grower partnerships. It maintains an urban tasting room in Oakland’s Jack London Square, offering a waterfront setting to sample its wines.
