Marco DiGiulio graduated with a degree in Fermentation Science from the University of California at Davis in 1985. After two years at Buena Vista Winery, he worked as Cellar Master at Pine Ridge Winery for more than four years. Marco next served as the Production Manager for Atlas Peak Vineyards, followed by his 1994 appointment as Winemaker for Pezzi King Vineyards. Just before the 1995 harvest, Marco became the Winemaker at Pepi Winery in Oakville. While making Pepi Wines, he also took charge of the Lokoya brand. It was at Lokoya that Marco’s reputation for making world-class Cabernet Sauvignon was first established when his 1997 Cabernet Sauvignon received a remarkable 98 points in the Wine Spectator.
Most of Marco’s wines score consistently in the 90’s among top critics, and in November 2007, Wine Spectator named Marco DiGiulio "one of Napa’s leading wine consultants." His wealth of experience and love of winemaking enables him to craft the finest wines from the California mountains and valleys that provide his inspiration.
Marco has guided the winemaking at the highly acclaimed, and Napa Valley focused, Girard Winery since 1999. In addition, he focuses on creating the Sonoma County based high quality Chardonnays, Cabernet Sauvignons and Zinfandels for Vintage Wine Estates.
