The Trentadue family arrived in Sonoma County long before their region gained a reputation as the Wine Country. In 1959, the Trentadues decided to flee the developers encroaching on their apricot and cherry orchards in Sunnyvale, the area known today around the world as Silicon Valley. To preserve their way of life, these hard-working Italian ranchers purchased 208 acres of land in Sonoma County's then remote Alexander Valley.

The Trentadues were among the very first to plant new vines in Sonoma County since the days of Prohibition. Italians love their red wines, especially hearty reds like Carignane. In 1962, the Trentadue family began planting new Carignane vines in addition to the 68 acres of old vines already growing on their ranch. Now more than 35 years old, these vines are among the oldest producing Carignane vineyards in America. The family remains steadfastly devoted to this grape, and their wine ranks indisputably among just a handful of top ranked California Carignane. Case in point: At the 1997 West Coast Wine Competition, Trentadue 1993 Carignane was awarded both a Gold Medal and Best of Class.
