Thank you to our exclusive event sponsor, Tonnellerie Berger & Fils! Tonnellerie Berger & Fils is a french artisanal Cooperage based in the Medoc since 1954. They produce custom toast oak barrels for wine ageing.


Attendees joined Tod Mostero, Director of Viticulture & Winemaking at Dominus Estate, as he works with Josh Widaman, Estate Winemaker, and Gustavo Aviña, Viticulture Director, of Pine Ridge Vineyards to begin the process of transitioning a now fallow vineyard to dry farming. Dry farming doesn’t mean you just turn off the water – it requires careful forethought before planting a vineyard, and strategic management once planted. To pique your interest here is a feature that shares more about dry farming at Dominus.
