Gnarly Head Old Vine Zinfandel is crafted using grapes from select vineyards throughout the Lodi region – known as the “Zin-famous” appellation. Lodi has an ideal climate for growing exceptional grapes – warm summer days and cool nighttime breezes from the ocean, in addition to sandy, well-draining soil. Our grapes are hand-selected primarily from the Mokelumne River area, home to some of the oldest and most respected vineyards in Lodi.
