Welcome to Zialena Winery

a fourth-generation winery in the heart of Alexander Valley


Named for our Aunt (Zia) Lena who was known for her warm hospitality and famous ravioli, Zialena is a family legacy presently nurtured by siblings Mark and Lisa Mazzoni. With a rich history dating back over a century, our Geyserville estate has been stewarded by four generations.  

Surrounded by Zinfandel and Cabernet vineyards, Zialena is a modern Alexander Valley oasis offering immersive tasting experiences at our stunning estate that explore our estate-driven portfolio of wines produced entirely on site. Our land is the heart of our family, our wines the legacy, and our concrete fermentation tanks the distinction.

To us, Zialena is the alchemy of family legacy, meticulously farmed estate vineyards, and the unique concrete process of seasoned winemaker Mark Mazzoni, all working together to cultivate wines of integrity and intention.
