‘Marcassin started out with 10 acres of vines planted to equal amounts of Chardonnay and Pinot Noir planted near Fort Ross in the Sonoma Coastal areas. The initial plantings for the Pinot Noir took place in 1992. This was followed by another wave of 12 more acres for Pinot Noir vines in 2002. The terroir for the Pinot Noir is mostly volcanic stones and rocky soils.

Today Marcassin vineyards produces wine from their Sonoma vineyards that have continued to grow in size. They also make wine from fruit owned by the Martinelli families planted in the Blue Slide Ridge and Three Sisters vineyards. The vineyards are planted on elevations that range from 80 to 1400 feet. The Chardonnay comes from older Wente clones, along with material from Dijon, Mt. Eden and Hyde. The Pinot Noir clones came from Swan, Martin Ray, Calera and Pommard.” — The Wine Cellar Insider
