color contributions from dark yeast slurry
« on: September 22, 2014, 10:19:16 am »
I have a porter fermenting now with s04. I would like to transfer my next batch directly onto the yeast slurry. I will not be rinsing the yeast. If I rack off as much of the beer from the yeast, how much will the color of the next batch be affected? I realize that I should go light to dark when reusing yeast but I had to get the porter brewed. 

I haven't decided what I will brew yet but I might do my oat pale ale which is roughly 7 SRM.
On Tap/Bottled: IPL, Adjunct Vienna, Golden Stout, Honey Lager
Fermenting: IPA
Up Next: mexi lager, Germerican pale ale

Not to cop out, but I think it's a lot of "It depends". I'd try to leave as little of the beer as possible from the initial batch. Maybe even rack off some of the top layer that you'd normally leave behind to a waste bucket, to try to clear off the cake as much as possible.

Yeah that was kind of my plan.

I am not too worried about it just more curious than anything. If I was doing something that had to be very light colored then I might feel different but if it ends up slightly darker it shouldn't be an issue...

I have done this before with a Dortmunder that turned out a deep copper color because the yeast came from a porter or stout.  I entered my dark Dort into a competition as an ESB and it took 2nd or 3rd.  Crazy, I know, but that was also about 10 years ago before some people knew better.  Still put a grin on my face though.   ;D

Unless the second beer is several times the volume of the first, it would be over-pitching to use the whole yeast cake anyway. I'd measure out what you actually want/need, and then you shouldn't have any issues.

Not too worried about that either. I have done this many times without issue. What are the effects of overpitching?

I am normally under pitching when using liquid yeast...

at best, boring ale with little to no yeast character. at worse a beer that works so fast the yeast eat everything before they get a chance to clean up after themselves leaving behind acetaldehyde (fresh cut green apples)

For one thing, the possibility of increased esters.
