NOTE: This WineFlavor 101 is much more than Brettanomyces 101; it is the most comprehensive seminar we’ve produced so far on the stylistic impact of this mostly-misunderstood microbe. You’ll be the first outside UCD to review our new Brettanomyces Aroma Impact Wheel. You don’t 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.
