After beginning a pre-med program at UC Davis, shifting directions and taking a winemaking internship, Marbue earned his degrees and began his winemaking journey. Marbue’s winemaking career includes work with an impressive selection of Napa and Sonoma’s famed wineries such as J Winery, Cosentino, Benzinger, industry giant, EJ Gallo and, most recently, Caldwell Vineyard. Marbue was named Bonfort’s 2018 U.S. Winemaker of the Year for his modestly sized but impressive portfolio of hand-crafted boutique wines. He contends that the culmination of these experiences led him to Italics Winegrowers where he is artfully crafting small lot, premium wine.
