In 1925, Guglielmo Winery was established the Santa Clara Valley AVA. The family’s roots can be traced back to the Piedmont region of Northwestern Italy, where Emilio Guglielmo was born. In 1908, he immigrated to New York and moved to San Francisco two years later.
Emilio had great foresight to purchase his vines in 1925, at the height of Prohibition. He found an idyllic piece of land near Morgan Hill in Santa Clara Valley. Emilio catered to a local customer base that consisted mainly of Italian, French and Basque immigrants. In the 1940s, his son, George, took over the business. The third generation currently runs the winery.
George E. Guglielmo is currently the winemaker. In 1969, he graduated from Fresno State with a degree in viticulture and enology. He introduced many new winemaking practices to the family business, including stainless steel fermentation tanks and small oak aging barrels. His first wine was the 1969 Petite Sirah.
Guglielmo Winery makes many different wines including Cabernet Sauvignon, Merlot, Sangiovese, Petite Sirah, Zinfandel, Chardonnay, Pinot Blanc, and Pinot Grigio. Many of these are estate bottled.
