2015 Convexity is made from a perfect growing season, winemaker Steve Matthiasson hand selected vineyard sites throughout the Napa Valley for this exclusive blend; predominantly from the Red Hen Vineyard. The grapes were harvested with a level of freshness rarely found in Napa Cabernet. This wine has vividly preserved flavors and is aged in neutral oak barrels with 20% new oak to round out the flavors.
