While he’s also responsible for wine production at Mettler Family Vineyards, it’s at Michael David Winery where Mettler’s stamina has been put to the test. Working closely with the Phillips family, which has farmed in Lodi since the 1850s, Mettler is laser-focused on maintaining quality while “continuing mind-blowing growth to over 700,000 cases of sales, and garnering top scores,” he says. Michael David Winery’s 2012 Petite Petit was ranked Number 2 on Wine Enthusiast’s The Enthusiast 100 of 2015 list.
