WineFlavor 101B: The Impact of Brettanomyces on Wine Flavor Profile


Friday Jan 11th 2013


Freeborn Hall, UC Davis campus


Save the Date: Friday January 11, 2013
Where: Freeborn Hall on the North Quad at UC Davis
Time: 9:00am to 4:00pm
Registration details are below.

NOTE: This WineFlavor 101 is much more than Brettanomyces 101; it is the most comprehensive seminar weve produced so far on the stylistic impact of this mostly-misunderstood microbe. Youll be the first outside UCD to review our new Brettanomyces Aroma Impact Wheel. You dont want to miss this!
Brettanomyces plays multiple roles in wine production. Previous programs have focused on ethyl phenol production and the role of Brettanomyces in wine spoilage. But Brett can produce a wide array of aroma compounds in wines, some of which are sought after or associated with complexity and regional terroir. We will introduce the Brettanomyces Aroma Impact Wheel which was derived at UCD V&E from descriptive analysis of different strains, GC-O analysis of Bretty wines, and evaluation of compound-spiked synthetic and natural wines inoculated with different strains of Brettanomyces. In this analysis we identified several commonly used descriptors associated positively with commercial red wines. We have used these descriptors to identify commercial wines that showcase these compounds. The program will conclude with a discussion of the controversial role of Brettanomyces in the production of quality wines.
The agenda, which can change slightly prior to the event date, is as follows:
