Genetic Drift in Yeast Strains and Its Impact on Fermentation Characteristics

This chapter discusses the concept of genetic drift in yeast strains and its effect on fermentation characteristics. It mentions a study conducted in 2007 that found no genetic drift after serially re-pitching yeast strains, as well as anecdotal reports from European brewers. The speaker compares genetic drift to sexual reproduction in yeast and notes that it may not occur as frequently as brewers think.
