Sourced from two Sonoma County vineyards— the Paul Larson Vineyard in Sonoma Carneros and a Trinchero Family estate vineyard in the eastern Russian River Valley. Both vineyards were selected for their cool climate—necessary to keep the pH low and the total acidity high—and for their rocky soil base responsible for the characteristic minerality in the wine. especially lovely, with its combination of crisp acidity, refreshingly bright flavors, and an expressive, lingering finish. - Winemaker Notes
