' Winery - Zialena Winery



Zialena is located at 21112 River Road in Geyserville, CA in the famous Alexander Valley. The winery sits on a 120-acre property that has been in the Mazzoni family for nearly a century. The winemaking facility covers 7,000 square feet with current production of approximately 3,000 cases. Its design and concept have been the ambitions of Mark and Lisa Mazzoni from their early days walking the vineyard with their grandfather and father. The dream was for a state of the art facility that could allow for every opportunity to implement the winemaking philosophy and style true to the heritage of their family and the wines they love. The winery includes 10 open top concrete tanks for fermentation, a first for Alexander Valley. A barrel room, wine laboratory, and the winemaker's blending office surround the concrete tanks and complete the winery. The facility began construction in April 2016 and was completed in February 2017. Tours and tastings are offered daily. For more information, please visit our tours and tastings page.
