In order to appreciate wine, it’s essential to understand the characteristics different grapes offer and how those characteristics should be expressed in wines. Cabernet Sauvignon, Merlot and Zinfandel are all red grapes, but as wines their personalities are quite different. Even when grown in different appellations and vinified using different techniques, a varietal wine always displays certain qualities, which are inherent in the grape’s personality. Muscat should always be spicy, Sauvignon Blanc a touch herbal. Zinfandel is zesty, with pepper and wild berry flavors. Cabernet Sauvignon is marked by plum, currant and black cherry flavors and firm tannins. Understanding what a grape should be as a wine is fundamental, and knowing what a grape can achieve at its greatest is the essence of fine-wine appreciation.
