2018 Symposium


Brettanomyces Symposium

Brettanomyces has long been viewed as a spoilage organism in the wine industry. Although the organism was first identified in 1930, only recently have we begun to understand the impact this yeast has on winemaking globally. In recent years, scientists have sequenced the genome, described genetic and physiological diversity within the genus, identified a range of metabolic products contributing to spoilage, and explored how Brettanomyces interacts with different wine environments and microorganisms. Join us as we update you on the latest research, discuss how winemaking practices influence Brettanomyces and what tools are available for control.

Tastings will explore the ways that Brettanomyces can alter the sensory characteristics of a wine beyond just “barnyard and Band-Aid”. You will leave this symposium with a better understanding of this organism, its impact on wine quality, and the latest strategies for its’ control.
