Winemaking: Where Art and Science Collide Tom Farella, Winemaker Farella-Park Vineyards Napa, California
Bioengineered Yeast – an Application Dr. Hennie van Vuuren University of British Columbia
The Debate:“Wild” or Cultured Yeast Wild Yeast Advantages • Wild yeast offer complexity and true “terroir” • Wild Yeast fermentations longer, more diverse • Some cost savings up front, they come in on the fruit • Easy to do, just wait for activity • Wild yeast are COOL – a great marketing angle Wild Yeast Disadvantages • Debatable. Can cause problems, too • If so, then can re-create fermentation profile • Runaway fermentations have cost ramifications • Raises risks of all unwanted organisms • Marketers ignore the risks, know that it sounds COOL
