Re-using yeast
|
|
Im wanting to reuse a wlp007 yeast cake. It's going to go into the exact brew it came from. But I can't see just racking on top of it into a filthy better bottle. My plan was to keg the night before, leave a 1/4" layer of beer on top of the cake, brew the next day, then swirling and pouring into a fresh carboy. Does that sound logical? Should I put in in first and rack on top of it, or fill carboy first.

I won't pour new wort into a bottle with all of the junk/krausen on the sides either. I've simply swirled the cake/beer then poured into a sanitized mason jar and put it in the fridge, letting the yeast settle out. The next day, I took it out of the fridge and let it warm to room temp. When it was time to pitch the yeast, I decanted the beer and poured in the slurry on top of the wort. It was one of my best beers to date.

If your sanitation practices are up to snuff (if they aren't, then they should be), then there is no reason you can't pitch right onto a cake from a previous batch. I do this all the time with really high gravity beers. It's like making a giant starter. Don't fear the trub, it doesn't cross over, as far as flavors, or whatever.

I agree....If the previous beer wasn't contaminated, and your racked without leaving your priary unsealed for a long time, then all is well. I too do it all the time with no problems.
If you are that concerned and want to do the extra work, then you might as well go what they show in the yeast washing sticky, and wash the yeast.

I've never had a contaminated beer, but something creeps me out about re-using a carboy with stuck krausen goo all over the top. I would wash it, but i've never tried that yet and I don't have the mason jars for it.
