When you’re farming in Sonoma, and you want the best, you call Phil Coturri to manage your vineyard. Phil is part of the powerhouse team behind Mabon, including Carolyn Duryea, Adrien Halpin, and Hourglass’s Tony Biagi and Jeff Smith. ‘Heritage Blend’ is a field selection from the head-trained vines of Rossi Ranch, planted in 1910. While the exact percentages of this inaugural release are unknown, even to the makers, the final wine is a composition of Zinfandel, Carignan, Petite Sirah, Grenache, and Cinsault. After fermentation, the wine is aged in 16 months French oak, half of which is new.
