' Zialena Winery - Winemaking Team

Winemaking Team

Mark Mazzoni, Winemaker and Fourth Generation Owner

Mark returned to Sonoma County in 2000 with the intention of learning the family trade.  Hired by Mike Lee of Kenwood Vineyards, Mark spent two vintages learning all aspects of winemaking. After a vintage abroad, he joined the team at Vineyard 29 and started making Cabernets under Philippe Melka.  Recognizing Mark’s wine making talent, Philippe tapped Mark to help him with a new venture in Sonoma County, Flanagan Wines in Bennett Valley where he oversaw planting of new vineyards, construction of the production facility, and the successful release of six vintages. He has been making wine exclusively for Zialena since 2014.

Jesse Giacomelli, Winemaker

Jesse joined Zialena after working six vintages in California as well as abroad in Argentina. These experiences included time with consulting winemaker Aaron Pott, Hanzell Vineyards, and Elyse Winery, where he was exposed to a wide variety of both old world and new world winemaking techniques. These diverse experiences drove Jesse to pursue his passion of crafting ultra-premium Cabernet Sauvignon, where he found the perfect home at Zialena.  Jesse earned a Masters degree in Viticulture & Enology at UC Davis, and currently lives with his wife Jenna and their son Luca and daughter Emery in Healdsburg.
