Gundlach Bundschu: 168 Years of Sonoma Wine with Katie Bundschu

Six generations, 168 harvests and one unforgettable six-wheeled vineyard vehicle: Katie Bundschu shares the story of Gundlach Bundschu, California’s oldest family-owned winery. Katie explains how Rhinefarm was established in 1858, how the Gundlach and Bundschu families came together, and how the winery survived Prohibition and generations of change. She also talks about leaving Sonoma to pursue a career in college athletics fundraising—and what eventually brought her home to the family business. Today, “Gun Bun” combines wine, history, regenerative organic farming and live music. Katie takes us inside the Pinz Excursion through the vineyards, the Donkey Bar, the winery’s amphitheater and historic Redwood Barn. She also discusses an unusually early beginning to Sonoma’s 2026 grape harvest. Over a glass of dry estate Gewürztraminer, Katie and host Tim Zahner explore library wines, Chardonnay, Tempranillo, farming at Rhinefarm and the qualities that make Sonoma Valley feel like home. During “We Get Questions,” Katie helps answer questions about the Bear Flag Revolt, finding great Chardonnay, sweet and semi-sweet Sonoma wines, visiting during the fall, dog-friendly businesses and how to convince someone to move to Sonoma.
