Alice Feiring is no stranger to controversy. Her debut memoir, “The Battle for Wine and Love: Or How I Saved the World From Parkerization” (Harcourt), hit Page Six three months before its release this month. The reason? Feiring’s taste for natural wine brought her up against the world’s leading critic, the bulldog-esque Robert M. Parker Jr., whose trademark 100-point scale and preference for concentrated, manipulated wines can make or break a vineyard. Yet in talking to the petite, soft-spoken, 50-ish redhead — who, over wine and tea in the Soho neighborhood of Manhattan, where she resides, will reveal only that she is “old enough to drink” — all one sees is a warm, free-spirited, former dance therapist who listened to her own palate and is not ashamed to write about it with humor, passion and chutzpah.
