i. Biography
Bob Trinchero has worked the cellar from inside the family business at Sutter Home Winery in St. Helena, where the work was built into daily life rather than separated from it by school or distance. The career reads less like a detour than a sustained apprenticeship in place: a name, a house, and a set of working decisions that became the basis of the craft.
Coming Up
Since 1968, Bob Trinchero has served as winemaker at Sutter Home Winery, and today he is vinifying Amador County Zinfandel. That length of service gives the work a clear throughline: harvest after harvest, the vocabulary of the cellar has been shaped by repetition, not reinvention. The emphasis stays on what the fruit allows, what the season brings, and what the winemaker can draw from each lot through steady attention.
Where They Are Now
At Sutter Home Winery in St. Helena, Bob Trinchero’s career remains tied to the same house that formed it. The value here is continuity: learning the rhythms of a winery from the inside and returning to them over time until process becomes second nature. The result is a practice sharpened by proximity, with the winery serving as both site and standard for the work. The technical markers are plain and useful: saignée, concentrated Zinfandel, dry fermentation, rosé-style runoff, and the stuck fermentation behind White Zinfandel. Those terms describe the field he has worked in, and they show a winemaker operating through method rather than manner. His contribution sits in those choices—how the wine is handled, how texture is managed, and how a ferment is guided when the lot calls for it.
Signature
White Zinfandel is the signature wine associated with Bob Trinchero. In trade terms, it marks a specific line of work at Sutter Home Winery: technical judgment applied to a wine that became part of the house’s identity and part of his own record.
