(Decanter) - Piedmont winery Trinchero has had to remove the family name from its wine labels in the US after facing a legal threat from the maker of the Sutter Home brand, according to reports. The website of the Houston Press said Trinchero Family Estates – the California-based maker of Sutter Home and Trinchero Napa Valley – had written to Agliano Terme-based Trinchero threatening legal action. Monica Riessent, export director at the Barbera d’Asti producer, told the site that the winery could not afford to fight the American Trinchero in the courts.
