"It's my belief that the wines are at their best when allowed to develop naturally with only the necessary interventions by the winemaker." - George

Third generation winemaker, George E. Guglielmo, grew up on the family wine estate in Morgan Hill, California and began absorbing many aspects of the wine business at a very young age from his father and grandfather. As a teenager, George began broadening his knowledge base by apprenticing with other local winemakers to learn as much as he could about grape growing and winemaking. He also completed Fresno State University's Viticulture and Enology program to supplement his knowledge of traditional winemaking techniques with the more modern aspects required to produce wines for today's marketplace. George's winemaking philosophy remains a blend of age-old tradition and cutting-edge winemaking science and technology. George produces his wines with minimal handling or filtering - believing that the wines are at their best when allowed to develop naturally with only the necessary interventions by the winemaker. He shares his family's strong belief that wines should be easy for everyone to enjoy at a reasonable price. His philosophy has paid off in the many award-winning wines he produces today that have been noted for both quality and value.

The heart and soul of Guglielmo wines, George is very involved with family, as well as many community organizations. He is a well-known fixture around Morgan Hill with his classic 1957 cherry-red Chevy Cameo Pickup.


As one of Northern California's wine pioneers, the Guglielmo family has been producing award-winning wines in the Santa Clara Valley since 1925, a winemaking tradition that has spanned three generations.

Born in 1883 in Gravere, an alpine village northwest of Torino near the French border in Italy's Piedmont region, family patriarch, Emilio Guglielmo arrived upon Ellis Island on September 19, 1909. For the next nine months Emilio worked his way westward arriving in San Francisco in June of 1910. Upon his arrival and establishment of himself he sent for his village sweetheart, Emilia, and they were married in November of that same year. For the next fifteen years they worked and saved with Emilio toiling away at a tannery and Emilia a French laundry. By 1925, with their saved earnings they purchased fifteen acres in Morgan Hill of Santa Clara Valley, commonly referred to at time as the 'valley of hearts delight' due to the bountiful orchards and rich agricultural community. It was at this time Emilio Guglielmo Winery, was founded.

In 1945, the winery was passed down to Emilio's son, George W. Guglielmo and his wife Madeline upon George W.'s return from World War II. Working together, the couple expanded the winery's estate vineyards and distribution channels. By 1969, George W., with the influence of his eldest son George E., began the implementations of new ideas into the family business. This period saw an introduction of new refrigerated stainless steel fermentation tanks and small oak cooperage, as well as the production of the winery's first premium varietal wine, a 1969 estate-bottled Petite Sirah.

Today, third generation brothers George E., Gene and Gary retain the family tradition of producing award-winning premium varietal wine from the now more than 100 acres of Santa Clara Valley estate vineyards, as well as wines from other premium wine growing regions within California.

Practices & Techniques

In the vineyard, bud break occurs in mid-March with harvest beginning in early to mid-September. Vineyard practices are designed to be as sustainable as possible. Fruiting zones are kept open to facilitate light exposure and disease resistance. Reduced irrigation techniques are employed to encourage vines to express themselves fully. Crop load are also matched to accommodate these rigorous conditions.

Estate Vineyards / AVA

Our vineyards are comprised of approximately 70 acres planted to Zinfandel, Petite Sirah, Merlot, Carignane, and Grignolino.

Our growing region is unique in that is a mixture of rural, urban, and suburban settings. The site is classified as Region II with regard to climate which is synonymous with some of the most famous appellations in the world. The soil type is classified as a Pleasanton Loam which is essentially a gravelly loam. This translates into a soil that is well drained and consequently well suited to grape cultivation. Climatic conditions are dominated by our costal influence from both the Monterey Bay in the Southwest to the San Francisco Bay in the North. Usually, fog hangs over the vineyard in the early morning, receding southward as the morning progresses. Damaging low temperature dips are well moderated by the costal influence that greatly minimizes the threat of frost damage.
