Leveraging Technology to Increase Sustainability
Winemaking Breakout Session

As water becomes scarcer and energy becomes more expensive, we need to look to new technologies for sustainability shifts in our winemaking practices.  

This one-hour session will cover some of the new technologies that already exist and how some wineries are using them to their advantage as they become more sustainable.

Nate Weis
Silver Oak and Twomey Cellars, California

A Napa Valley native whose father is also a winemaker, Nate grew up with wine on the table and a drawer full of t‐shirts emblazoned with winery logos. His first job after graduating with honors from UC Santa Barbara with a BS in Biopsychology was as a “cellar rat” at Groth Vineyards & Winery. “I loved that first harvest, so I packed my bags, dropped my application for UC Davis in the mail and went off to Hawke’s Bay, New Zealand to work another.” After earning an MS in Viticulture and Enology from UCD, he was hired as cellar master at Etude, and then spent two years as assistant winemaker for Patz & Hall Wine Company.
