Rogue and Papazian have their own yeast strains (PacMan and Cry Havoc, respectively). Do you know how they got there? Lots of trial and error? Pitching multiple strains? Let's say I pitch a bunch of different strains into a batch and stumble on something awesome. I'm still bound by not repitching past the 6-8 generation, and the core culture only lasts 2-3 months. If I discover the next amazing strain through experimentation, what do I do then? |

It's mainly time (many many many generations) and environment. You could theoretically isolate yeast from the fermenter that have different properties like flocculation, attenuation, flavor profile etc. and then continue to focus on the desired traits until they behave the way you want. Yeast reproduce asexually under normal fermentation so pitching 2 strains won't create a 3rd new one. I recall reading that Cry Havoc was cultured up from a Budweiser keg. Maybe if you keep using the same yeast for 20 years one of the labs will put out a special edition for you :) |

From my very limited understanding on yeast, I believe you create your own new strain. While you may only repitch the same yeast 6-8 generations, the initial starter can be grown through doubling techniques. I need to learn more about how this works, but I believe if you were to collect some yeast from, say, your 4th generation of repitching, and expand this, and pitch it into a new batch, and repitch a few times, and harvest, etc.... Then you'll have your own unique yeast. Or, I could be a bit off. |
