Fermenting on top of trub?

[johnhenryrolf]

I know that I've read about this before (can't seem to find it though), but has anyone had success brewing the same day that you bottle, and just reusing the trub for your next batch?

Yes, search on "pitch on a yeast cake". You usually don't want to use an entire batch's worth of yeast, but people do it all the time.

Oh, yes, lots of people have done it, including me.

However, I've only done it when using the yeast from a smaller batch of a lower OG beer to a larger batch of a higher OG beer.

Generally, you can have better results with just scooping out a portion of the yeast cake and using that for your new beer, and saving the rest in a sanitized jar in the fridge for next time.

will give great information, as well as a super easy way to save the yeast from the first batch and use in the next three batches (give or take).

Thanks, will definitely read...I'm going to bottle tomorrow, and I'd also like to brew at the same time! Thanks again.

Well...I chickened out! Maybe I'll do it next time, just too scared of an infection.
