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, Assistant 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 in Healdsburg.
Chelsey Azevedo, Harvest Intern
Chelsey Azevedo never even thought about becoming a winemaker when she chose to go to UC Davis, she wanted to be an anesthesiologist. She took a few Viticulture and Enology classes, did an internship, and met enthusiastic VEN professors and wine people. That’s when she decided winemaking was what she wanted to do with her life. She graduated in March 2017 with a bachelor’s degree in Viticulture and Enology from UC Davis. She has worked two harvests with Matchbook Wine company in Zamora, California while still in school. Immediately after graduating headed to New Zealand to do a harvest abroad at a custom crush facility, New Zealand Wineries LTD. After New Zealand, headed to St. Helena to work for Louis M Martini, working as a winemaking intern in their No. 254 also known as their micro winery. At Martini, she did just about everything in the cellar in addition to creating blends and sensory evaluation with the winemakers. Now she is a valuable member of Zialena’s wine making staff for the 2018 harvest. Chelsey loves working in the wine industry because not only does it allows her to make a product that brings many people together, it enables her to travel the world while making new connections.
