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.
Tod Mostero | Director of Viticulture & Winemaking at Dominus Estate
Director of Viticulture and Winemaking, the French connection runs strong through Mostero, who studied in Bordeaux and trained at Château Haut-Brion, Domaine de la Romanée-Conti and Établissements Jean-Pierre Moueix.

Josh Widaman | Estate Winemaker at Pine Ridge Vineyards
After 20 years producing highly rated Napa Valley wines, Josh Mendoza-Widaman found his way back to the Stags’ Leap district as head estate winemaker for Pine Ridge Vineyards.

He now oversees Pine Ridge’s estate vineyards, most notably producing elegant and expressive Cabernet Sauvignon.
Gustavo Aviña | Viticulture Director at Pine Ridge Vineyards
Since 2003, Gustavo has worked intimately with every Pine Ridge Vineyards estate property. He and his team understand the soils and climates of the winery’s vineyards in five different appellations: Stags Leap District, Howell Mountain, Oakville, Rutherford, and Carneros.

These assessments help identify opportunities to maximize irrigation uniformity and efficiency.
They will be joined by Tom Shapland, Co-Founder and CEO of Tule Technologies and James Nichols, President of HotSpot AG, who will share their technologies, often used in partnership, that help precisely target the timing and amount of irrigation, improving both irrigation efficiency and grape quality. A grower who has used these technologies shares their experience and benefits.
