13 Appelations - Against this trend of vineyard-designated wines comes THIRTEEN — a wine made not from not just one vineyard, but from a baker’s dozen, each one more esteemed than the next. What distinguishes these vineyards is that they have been chosen as the best representatives of their respective sub-appellations: Howell Mountain, Rutherford, etc. Napa Valley has 13 of these sub-appellations or did when we picked the fruit.
