In a ToutSuite Social Club videoconference, Cathy Corison explains how her Corison Vineyards deliver such extraordinary fruit to their winemaking practice. I ask her about the age of the vines in her vineyard. She tells us that their vineyard is among the last of the old cabernet vineyards in Napa. Rather than bulldozing and replanting en masse, she replants individual vines when they die. The average age of the vineyard is about 40 years. The yield is one and a quarter tons per acre. Few other winemakers are willing to trade yield for quality in the way that she does. In my humble opinion, which agrees with that of many other people and institutions, Corison Vineyards' practices pay off in helping them to bring to the public wines of uncompromising distinction. This type of viticulture is one of the most attractive and rare genotypes that I seek out when I explore wine countries, regardless of what the varietal might be.
