Press Release: Quality vs Yield: the Age-Old Debate to Strike Balance

General Session at WiVi, March 20
March 04, 2013

Paso Robles, CA – Quality versus yield is the age-old debate between growers and winemakers. How to find ways to balance the two promises to spark a lively discussion during the general session on Wednesday, March 20 at WiVi Central Coast, the industry’s newest and largest tradeshow and symposium. Presented by WINE BUSINESS MONTHLY and Precision Ag Consulting, WiVi will be held March 19-20 in Paso Robles, Calif. Attendees interested in the complete speaker line-up and attending the comprehensive program can register at

Controlling quality and managing yield are two key considerations, which influence grape growing and winemaking decisions. Balancing the two is difficult and often creates a conflict for grape growers and winemakers. Experts: Keith Patterson, formerly the head of the viticulture program at California Polytechnic University, San Luis Obispo; Mark Greenspan, Ph.D., viticulturist and owner of Advanced Viticulture; and Scott Hawley, consulting winemaker and owner of Torrin Vineyards in Paso Robles; will discuss their experiences to strike the perfect balance between quality and yields. The session will be moderated by Lowell Zelinski, Ph.D., owner of Paso Robles-based Precision Ag Consulting and co-founder of WiVi.

According to Zelinski, as a young wine region, this topic is of major importance to Central Coast winemakers and growers as they work together to strike a balance.

“Winemakers and growers may not agree about every aspect of growing and winemaking,” Zelinski said, “but they do agree that producing premium quality wine grapes is the key to the success of making any wine region a great one. The question really is whether the perfect balance between quality and yield can actually be achieved?”

Zelinski said most winemakers and growers want to work together to achieve the best result, so understanding what research has been done, how it has been applied and what these experts think about it makes this a hot topic for the Central Coast wine industry.
Winemakers, viticulturists and industry business owners are invited to WiVi to network with their peers, hear industry updates and walk the sold-out tradeshow floor featuring 120 suppliers. Educational credits are available for all viticulture sessions. A complete schedule is available at
