Alice Feiring, a wine writer noted for her preference for natural wines has come out a with a new book. This one The Dirty Guide to Wine: Following Flavors from Ground to Glass focuses on the different bedrocks and topsoils and how they affect the acidity and tannins in wine. To test the theory I attended a very special tasting dinner at Rouge Tomate, where Feiring and co-author Pacaline Lepeltier provided proof for the pudding. Here we sampled wines from each soil type: Igneous (volcanic); Sedimentary (sanstone/limestone); and Metamorphic (slate/schist); plus the Alsace region, which is considered a category in itself. (see the dinner) Alice takes on the subject in a diverting and engrossing way, sharing her personal stories from travels around the globe with her goal of encouraging people to look beyond the grape. With each category, Feiring explains the nature of the individual soils and recommends specific wineries. A clever wine tasting primer at the end of each chapter is designed to further your eduction, and HOBNOB suggests you use this as an excuse to host your next wine tasting. Throughout you’ll learn about the best natural wines, with which, Feiring alludes, eliminate hangovers, due to the lack of added sulfur dioxide. That may be the best news of all!
