I am about to keg up or possibly rack into another carboy a saison I have going. I plan to bottle condition it at some point. I am going to add the dregs of a bottle of Orval.
What I am wondering is this. If I add the dregs and let it sit a bit, I assume the bugs in there if they are still viable will multiply. Then, if I were to draw off some of this beer and add it to another could I then "infect" another batch of beer? Or maybe later once it is bottle conditioned can I use the dregs from that bottle again?
I am a little fuzzy on the process of this. The collective wisdom seems to be that you want to culture these bugs in already fermented beer. What I understand is, if you attempt to culture up just the dregs in a regular starter you will most likely get a larger population of the Sacchromyces strain than the Brett that is in there because conditions are more favorable for them at the point. Whereas if you add the dregs to already fermented beer the Sacch. won't have as much to eat so the Brett will take more of a hold. Is my understanding correct?
Could you then perhaps culture the dregs on their own by adding them to a small amount of beer rather than wort?
