Modern Paso Robles winemaking began in 1964 when Dr. Stanley Hoffman, a Beverly Hills cardiologist, planted the region’s first Pinot Noir and Chardonnay vines on his 1,200-acre ranch in the Adelaida hills (Cabernet Sauvignon followed on the property, by most accounts within the decade). Guided by Jack Foote, the county’s agricultural advisor, who recognized that the ranch’s high elevation and chalky, lime-rich soil closely resembled Burgundy and Bordeaux, Hoffman succeeded where few had tried in a landscape long known mainly for Zinfandel. In 1973, the Hoffmans moved to Paso Robles full-time and brought on the legendary enologist André Tchelistcheff as a consultant, and by 1975 their Hoffman Mountain Ranch (HMR) Winery had become the first large-scale modern winery built in San Luis Obispo County since Prohibition. Soon after, Gary Eberle and Cliff Giacobine planted roughly 700 acres at Estrella River Winery on Paso’s east side, establishing what became the largest commercial Syrah planting in the state at the time.

This pioneering effort paved the way for Paso Robles to gain formal recognition as an American Viticultural Area (AVA)(opens in a new tab) in 1983, becoming the nation’s 44th. Today, the Hoffman legacy remains physically divided between two historic sites: 419 acres of the original ranch, including the vineyard Hoffman planted in 1964, were purchased in 1994 and now form the heart of Adelaida Vineyards & Winery, while the remainder of the property was acquired in stages by the Daou brothers, starting in 2007 and completed in 2012, and now sits atop what is known as DAOU Mountain. Together, these sites preserve the footprint of a pioneer who helped shape the story of Paso Robles wineries and transformed a quiet ranching region into a premier wine destination now home to more than 200 wineries.
