Moonstone Crossing wines are made from select grapes grown in small, hillside vineyards from the Napa, Sonoma, Mendocino, and Amador appellations. Moonstone Crossing wines are hand-crafted in small quantities using traditional-style winemaking techniques. The wines are neither pumped, fined nor filtered, with only a minimum of sulfites added in the winemaking and bottling process. Specializing in hearty, full-bodied, rich-flavored red varietals, present and future offerings include Sangiovese, Barbera, Zinfandel and Old Vine Zinfandel, Cabernet franc, Syrah, Petit Sirah, Merlot, Cabernet sauvignon, Carignane, Nebbiolo, Aglianico, Pinotage, and three blends: Rhone-style, Bordeaux-style, and Super Tuscan-style blends. Zinfandel and Souzao ports along with a crisp but smooth, lightly oaked Chardonnay are also available in addition to the red varietals.

Moonstone Crossing is a winery dedicated to the proper development and aging of its wines. All red wines are aged in French and American oak for 22 to 36 months before bottling and then bottle aged an additional 6 months prior to release.
