Welcome to our home

Named for our Aunt (Zia) Lena who was known for her warm hospitality and famous round ravioli, Zialena is a family winery 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.

Grounded in practice

As farmers, winemakers, and stewards of our Geyserville property since 1931, winegrowing is in our DNA. During Prohibition, Mark and Lisa’s great grandfather Giuseppe Mazzoni and his brother-in-law Abramo Trusendi produced jug wine inside the iconic barn on Hwy. 101 in Asti, advertising "Dr. Pierce’s Medical Discovery." Later, Giuseppe acquired the property as a winemaking facility and vineyard. His sons, Fred and Jim, continued the tradition, making wine there through the 1970s, selling each jug for $2.50. Jim’s son, Mike Mazzoni, took over vineyard production and taught his kids, the current sibling team in charge of Zialena, the ins and outs of the family trade.

Today, Mark and Lisa Mazzoni focus on cultivating premium fruit for our winery partners and vinifying great wine at an affordable price for family, friends, and guests. The legacy of their predecessors remains relevant daily, their memory an inspiration for Zialena and the foundation for our longevity. With a genuine love for what we do, we welcome you to be part of our story.

Stewardship

We are honored to be part of the Geyserville community and to continue the long history of viticulture in the area. As guardians of the Mazzoni legacy, we practice nature-led, sustainable farming and low-intervention winemaking. To have minimal impact on the environment we are solar powered, handpick our grapes, have no trucks on the road and we don’t filter or fine our wines. All decisions are made with intention, integrity, and care for the environment and posterity in mind. We invite you to explore our estate-driven and distinct wines produced entirely on site.

From our family to yours

For the Mazzoni family, Aunt Lena's legacy transcends generations, serving as a beacon of tradition and inspiration. Her spirit lives on in every bottle of Zialena wine, embodying the timeless values of family, heritage, and culinary craftsmanship.

Welcome to Zialena, make yourself at home.
