Wild Yeast Fermentation: “There’s No Such Thing”

Wild Yeast Fermentation: “There’s No Such Thing”

6

(FermentationWineBlog) - Some fairly stunning information concerning the idea of “Wild” or “Indigenous” yeast is coming to light that has implications for wine marketing and wine making. How shall I put this? Let’s try this: If you think your wine went through fermentation driven by wild yeast or if you think the wine you are drinking was produced via a wild yeast fermentation, it probably wasn’t.

This is the startling conclusion brought to light in a study undertaken in British Columbia and reported upon by Andy Perdue in the new August 2013 issue of Wine Business Monthly. Here’s the money quote:

Regardless of which yeast started the fermentation—indigenous or otherwise—a dominant commercial strain took over during the process, essentially wiping out any other forms of yeast that might have been present.”

AMAZING
The results of the three years study of three wineries in British Columbia under the auspices of the University of British Columbia were first disclosed at a talk given at last summer’s British Columbia Wine Grape Council’s Annual Meeting.
