I have some questions about growing bottle dregs

[CrashNebula]

How do you guys store them? How long do you store them? Is there a thread in this? Any insight would be appreciated I have harvested and put them in a starter wort they are sitting in mason jars with plastic wrap on them but it seems like the could pop from the co2

hopefully you used a very low gravity starter, like 1.010. I would suggest this any time you are collecting bottle dregs, sour or not. Sour dregs can be stored a lot longer since they will not die as quickly as sacch. I typically keep them at cellar temps and not in the fridge, just due to the lag time after being in the cold. As far as growing a starter, let it spend at least a week in the small 1.010 starter. Keeping that in a jar is perfect, only shaking it up a few times here and there. After that, you can certainly move that to a higher gravity starter, around 1.030 or so, and throw it on a stir plate for another week. You should have a healthy pitch at that point. If the slurry isnt large enough, just do another step.

I usually grow them in the bottle for 2 steps, first like 50ml of typical starter wort, then up to 200ml, then pitch into a bigger flask to make my starter or step up again. I harvest all my yeasts from decanted starters, so they are basically stored in the weak starter beer. The yeast has lasted more than 6 months without much delay on getting going in a new starter
