Meet Our Maker

Sonoma Strong

Ondine Chattan is a passionate Sonoma County winemaker with experience ranging from cult boutique producers to notable household name brands. Her love of the diversity of Sonoma and California at large fuels her enthusiasm for making a range of varietals from Sauvignon Blanc to Cabernet. Ondine takes a hands-on, multidisciplinary approach to winemaking- a credit to her years spent earning a Master’s of Science in Enology from Fresno State and a Bachelor of Science from Cal Poly San Luis Obispo.

Ondine launched her winemaking career at Cline Cellars, following her graduate work she joined Ridge Vineyards, and then spent the next 18 years at Geyser Peak before joining SHARE A SPLASH in 2017.


Having been a part of this region for 20 years now and being a part of taking it to the next level…somewhere more present on the world stage, has been so rewarding.


The work has to happen in the vineyard and that means building strong relationships.

Ondine joined SHARE A SPLASH wine co. in 2017, after founding winemaker Dennis Hill introduced her to founder & CEO Yoav Gilat. They immediately bonded over the easy approachability of their wines coupled with Yoav’s unbridled enthusiasm for Sonoma County. 2022 marks her fifth year with the company, and her fourth helming the winemaking team after Dennis’ departure in 2018. She has brought some of her favorite grape growers into the SHARE A SPLASH winery family and expanded sourcing relationships with an eye on always refining style and quality.
