Owner Gary Eberle, who's been making Paso Robles wine since 1973, is sometimes called the "grandfather of Paso Robles's Wine Country," because many of the new vintners in the area honed their craft working under his tutelage. A visit to Eberle Winery includes a tour through its underground caves, where hundreds of aging barrels share space with the Wild Boar Room, site of Eberle's monthly winemaker dinners featuring guest chefs from around the country (always held on Sat nights; the prix-fixe meal is around $120, including wine).
