The King of Zin


After years of making wine out of their family home, Kent and Kathy Rosenblum took their love of winemaking to the next level and founded Rosenblum Cellars in 1978. In partnership with several close friends, and with Kathy acting as his assistant winemaker and helping with the crush, Kent made Rosenblum Cellars’ first vineyard designated zinfandel. Inspired by their early winemaking success, Kent began to focus on crafting vineyard designated wines using grapes farmed from mountainside, head-pruned, old vines. He would search Sonoma and Napa, Santa Barbara, Paso Robles and beyond, just to find the best vineyards and growers in California.

In 1987, Rosenblum moved his commercial operation from its location next to The Dead End Bar in Oakland, to a facility next to the Oakland-Alameda Ferry building on the island of Alameda, and the rest of the journey became history. Along the way, Rosenblum Cellars became one of the original “three R’s of Zin” (along with Ridge and Ravenswood), and the practicing veterinarian even managed to pick up a new nickname instead of Doc, becoming “The King of Zin”. Long hard work eventually paid off, and the Rosenblums were able to sell their winery to Diageo Chateau & Estate Wines for a reported $105 million in 2008.

Join us as we talk with Kent about his humble beginnings, his love for wine, and the dozens of vineyard designates to come out of his prolific winery. You may even want to open a Zin or Petite…we did.

    As a long time zinhead, I really liked this show. Shocked to hear Jay actually likes Zin, and most appreciative of Eric for putting up with it! I think Kent sold out at exactly the right time (just before the crash), but I don’t expect the new owners to continue with his passion

    This was the perfect time to come out of the closet about my liking Zin.

    Talk about selling out at the right time! Bravo for Mr. Rosenblum. The quality of Ken’s wines speak volumes for this wine sage. It’s nice to know that he’s NOT DONE YET. Great interview guys, quality give and take as always.

    I’m also a Zinfandel lover but I’d never tried anything from Rosenblum Cellars – I’m not sure why not. So the day after listening to the podcast I tried a bottle of the Annette’s Reserve with a grilled steak. Nice.

    Thanks guys.
