Fifth generation winemaker Dustin Heineman talks about growing up on South Bass Island and operating the family vineyard. His great-great grandfather Gustav, a German immigrant, began planting grapevines in the 1880s. Heineman’s Winery has been in business for 137 years, produces more than a dozen varieties of wine and is the oldest family-owned winery in Ohio. He also covers the 1897 discovery of Crystal Cave, the largest known geode in the world, and how it saved the family business during Prohibition.
