Sutter Home Winery

The winery remained abandoned until 1948, when it was purchased by John and Mario Trinchero, immigrant brothers from New York City whose family had been active in the Italian wine business.

[2] For years they operated “mom-and-pop” style, selling to their Napa Valley neighbors, who filled their barrels and bottles at the winery's back door.

[3] A fortunate accident occurred during the making of the 1975 vintage, as some 1,000 gallons of bleed-off juice from red Zinfandel refused to ferment to dryness, retaining a substantial amount of sugar, and Trinchero put the wine aside for the time.

[6] In collaboration with Bob Torkelson, the Trinchero family manages the large winemaking organization, overseeing operations from grapegrowing and production, marketing and sales.

In 2004, Trinchero Family Estates winery produced about 10 million cases a year, with Sutter Home White Zinfandel being 95% of those unit sales.
