Grapegrowing Breakout Session

Master the World, Inc.

Winegrowers are continually challenged to adapt to a changing world, whether driven by climate change, consumer preferences, market conditions, labor availability or the regulatory environment. However, when it comes to what kinds of grapes are grown, many winemakers and growers resist changing varietals….except for our guest speakers!

Join us as we learn and taste commercially produced, pure varietal wines from Dr. Walker’s new Pierce’s Disease-resistant hybrid grapevines. Chuck Wagner (Caymus, Napa Valley) and Adam Tolmach (The Ojai Vineyard) will share their experience in growing and producing wines that could pave the way for our industry. While always striving to deliver better quality wine, investments into what is sustainable for your site needs continues to be a focus. This session will examine some of the varietal options available to winegrowers and the benefits of those varietals.

Attendees have the opportunity to purchase a tasting kit for $75 with six different wines in 187 mL bottles (a pour and a half).

Molly Scott
JUSTIN Vineyards & Winery, California

Molly Scott, Director of Grower Relations, JUSTIN Vineyards & Winery

Growing up in Seattle’s wine business inspired Molly to study Wine & Viticulture in California; the weather is much nicer there after all. Her need to understand how to grow a grapevine and make wine led her to become an integral part of the vineyard team at JUSTIN. It only took one quarter of classes in the vineyard and she was hooked on farming. In 2009, after graduating from Cal Poly, San Luis Obispo with her Bachelor of Science degree in Viticulture, Molly and her husband chose to stay on the Central Coast and join the growing wine industry. Ten years and two boys later, they are proud to call Paso Robles home.

Adam Tolmach
The Ojai Vineyard, California

Adam Tolmach went to UC Davis and studied viticulture and enology, and after graduating in 1976 he settled down on the property his grandfather bought in the Ojai Valley in 1933 to farm sweet corn and melons, selling them at a roadside stand. After two years of this satisfying, yet difficult and nearly profitless work he sought employment in his field of study.


Chuck Wagner
Wagner Family of Wine, California

Chuck Wagner was born into a family of farmers and winemakers with deep roots in Napa Valley. In 1857, his great-great grandfather captained a wagon train to California from Bible Grove, Missouri.
