This is a project founded by Tess Perliss and Aaron Pott to celebrate one of California's true treasures, Zinfandel. Tess and Aaron met when, in 2007, Aaron came to the Perliss family estate in Calistoga and convinced them to plant Cabernet Sauvignon on the family's empty pasture. From there, he took over winemaking operations on what has become one of the northern valley's most respected estates. Wingspan, however, is an exploration primarily of a 120-year-old vineyard, Del Barba Ranch. The vineyard sits at the base of Mount Diablo and is dry farmed organically.
