Though the blend has changed over the years, White Coat (named for Larrys past as an Emergency Room physician) comprises rich, textured Roussanne from Rattlesnake Ridge on Howell Mountain moderated by acidity and structure of Grenache Blanc from Pesenti Vineyard. Recently weve added a bit of Vermentino from Amador, as well as some extra Grenache Blanc and a little Verdelho from Lodi. The result is a unique, dynamic white wine that is truly California. Turley Wine Cellars makes forty-seven wines from over fifty vineyards, the vast majority of which are single vineyard designate Zinfandels and Petite Syrahs. By focusing on old vine vineyards in particular, Turley aims to both create and preserve Californias unique winemaking culture.
