Nestled high in the Mayacamas Mountains (which were once a seabed), the MVAVA is a relatively small AVA of around 25 square miles with approximately 1,000 acres planted to grapevines. Some of the steepest vineyards in California, certainly in the Napa Valley, are to be found here: farming on a 30° slope is, to me, the very definition of hillside viticulture. Difficult to farm, the shallow volcanic soils mean that crop yields can be a full 50% less than what a grower could expect to harvest from a valley floor vineyard (for Cabernet sauvignon that could mean a mere 2 - 2½ tons per acre). The Mayacamas range can receive nearly twice the amount of rainfall than the valley floor, a rather soggy 35 - 40 inches a year. Abundant with firm tannins, brambly is a word quite often used when describing the red wines of the MVAVA. And apparently the wines age very well. I have had a few MVAVA wines, but not a lot.
Notable wineries (to me) are; The Hess Collection (in part for being on the site of the former Christian Brothers winery, Mont La Salle), Rubissow (I had a wonderful hillside-viticulture field trip up there once) and Mayacamas Vineyards and Winery (where my NVC viticulture professor Dr. Krebs was once employed as the vineyard manager. And also where A Walk in the Clouds, starring Keanu I-couldn't-act-my-way-out-of-a-paper-bag Reeves, was filmed).
Ten down, six to go.
