Gundlach Bundschu

Gundlach Bundschu is California's oldest family winery, founded in 1858 by Bavarian immigrant Jacob Gundlach and still run by the same family six generations later — a genuinely rare feat in American wine. The Rhinefarm estate in Sonoma Valley is their home base, a single property that has been farmed continuously for over 160 years and produces everything from crisp Gewürztraminer to serious Cabernet Sauvignon. They're also known for being refreshingly irreverent — their marketing has always had a sense of humor that matches well with their approachable, terroir-driven wines. Worth seeking out for the Tempranillo and the estate Merlot, which consistently punch above their weight.
