Meet the Castello's Winemaking Team

Castello di Amorosa produces classically structured Italian-style wines that reflect California’s unique climate, soil, and growing conditions.

Our philosophy is to make elegant, intensely flavored, and well-balanced wines that showcase the “terroir” of each unique vineyard site. In this way, we can experience the flavor and aromas of the vineyard itself.

We are committed to using traditional approaches to the craft of wine growing and winemaking, but also incorporate modern techniques and equipment when it improves quality.

Castello Vineyard Team

Brooks Painter, Director of Winemaking

Brooks Painter has been a winemaker for over 30 years. His impressive resume includes positions as operations manager at Robert Mondavi Winery in Oakville and winemaker at Stag’s Leap Wine Cellars, Leeward Winery, and Felton-Empire Vineyards.

Brooks has been director of winemaking at the Castello since 2005, producing a variety of highly acclaimed 90+ point wines that have gained recognition from Robert Parker, Wine Spectator, and Wine Enthusiast. In 2014, he received the distinguished Winemaker of the Year award in the American Fine Wine Competition.

He discovered his passion for wine while pursuing a bachelor’s degree in chemistry and biology from the University of California at Santa Cruz. His work has been published in The American Journal of Viticulture and Enology, Biochemistry, Practical Winery, and Wines & Vines. Brooks is a professional member of the American Society of Enology and Viticulture and a former chair of the Microbiology Committee for the California Enological Research Association.

For the past 15 years, Brooks and his wife Beth have lived in Napa. They’re actively involved in the Napa Valley community, charitable organizations, and long-range public planning for local city and county government.


Peter Velleno, Winemaker

Peter Velleno studied winemaking, brewing science, microbiology, and food engineering at the University of California at Davis. In 2003, he was the only student to graduate with a bachelor’s degree in fermentation science.

After graduation, he went to work in the laboratory at William Hill Winery, where he quickly worked his way up to assistant winemaker specializing in Chardonnay production. Peter went on to work for the ultra-premium small winery Hartwell Vineyards, where he helped craft some of the most highly regarded Cabernets in the Napa Valley.

Peter’s career path took a sharp turn in 2008 when he joined Castello di Amorosa as the associate winemaker. He was promoted to winemaker in 2014 and manages the production of the Castello’s wines. If asked, he will tell you that making wine in a Castle is even more fun than it sounds.

Peter and his wife Lauren have lived in Napa since 2003. They have two children and enjoy playing tennis, biking, cooking, and spending time outdoors with their dog Nora.
