Yeast Genetics and Flavor
If this is a naive question please forgive, but what is unique about the different strains of yeast that would allow them to create/impart different flavors? Is it something with the biological make-up of a particular strain or some other native charachteristic to yeast metabolism? As a follow-up can the yeast organism be sufficiently isolated to "breed" for particular flavor profiles...Yeast Growth
First, thank you so much for giving us some of your time. My question concerns yeast growth as it relates to flavors in beer. I have read several articles mentioning that yeast growth is important to flavor production in beer, and that the amount of yeast growth is related to the amount of yeast pitched. My own completely unscientific experiments have lead me to believe that I produce more "...Yeast Multiplication
I've read somewhere (but cannot find it anymore) that yeast will multiply until they reach a certain density (cells/ml) or exhaust their supply of sterols, whichever comes first. But, then I've also read that sterol-deficient yeast (presumably from under-oxygenation at pitching time, right?) will have weak cell membranes, ultimately resulting in low alcohol tolerance and high Final...Yeast Mutations
I have read repeatedly that yeast will mutate after several reuses in the homebrew environment. If the yeast mutate at this high of a rate, how do breweries maintain consistent yeast characteristics, and how are pure cultures maintained without mutations? If yeast mutate at such a rapid rate, how are yeast characteristics maintained over the period of many years as we have seen. It seems to me...Our Products
