One of the main resistances to phasing out glyphosate is increased labor and equipment costs. However, the costs of herbicides and fertilizers have risen dramatically, so increased labor demands can be offset by reduced supply chain purchases. 

In addition, leaders like Grgich Hills Estate have shown that regenerative organic farming can be cost-effective. According to an analysis by Brotemarkle Davis & Co. LLP accounting firm, the average annual per acre cost of vineyard management in the Napa Valley is $14,800, with $3,800 in depreciation. At Grgich, they spend $11,000 per acre, with only $1,300 in depreciation due to the longer life of their vineyards. 

Learn from regional leaders about the practical costs, benefits, and ROI of herbicide-free, organic, and regenerative vineyard management.

Confirmed Speakers:
• Ivo Jeramaz, Grgich Hills
• Phil Coturri, Enterprise Vineyard Management & Winery Sixteen 600
• Brad Kurtz, Gloria Ferrer
• Brenae Royal, St. Supery
