A former executive at AOL and Apple, Barry Waitte likes wine. He also likes horses—in fact, he competes in a grueling event known as “endurance horse racing.” When he decided to retire from Silicon Valley, it was only natural that he start a winery in a prestigious horse-training center, Calistoga’s Sundance Ranch. Step into Tamber Bey and you’ll taste wines in a courtyard surrounded by some pretty classy stables. And the wines that Waitte and his wife, Jennifer, produce are dark, earthy thoroughbreds too.
