Gnarly Head wines began with a vision and a vine. In 2004, on a mission to make a serious Zinfandel.Ã‚Â Winemakers journeyed to Lodi in central California in search of the famed old vine Zinfandel vineyards. Grown in the head-trained, spur-pruned method for over a century, these vigorous gnarled vines produced more ripened red fruit than they had ever seen. They took it as a challenge to create the biggest, boldest Zinfandel they had ever made. The result was authentic, structured wines with a hint of something unexpected. Something Gnarly.
