I generally rinse my yeast cake (put it in a jug with a bunch of clean water, shake it up and let it stratify into the yeast/junk/water and then siphon out the yeast portion) and do 3-5 repitches. I haven't ever had a problem with this, and generally by the 5th batch I'm going to move on to a new strain. Sometimes, I just don't bother with the rinsing if I am pitching into something similar, or from something very delicate into something robust (think cream ale pitched into a RIS).
I also try to leave most of my trub in the kettle, but invariably there ends up being 0.5-1" of junk in the bottom of the carboy at the end.
For the hoppy beer to something repitch, does the trub really matter? I was under the impression that it was the hop oils in the beer (regardless of the trub material) that was coating the yeast cells and inhibiting their ability to take food in/out and reproduce. Isn't that the basis for the antimicrobial aspect of hops (I don't know, but that is what I thought was the case)? If that is the case, even with no trub you would have the hop compounds coating the cells. Perhaps just repitching more yeast can compensate for this, but you also get some residual bitterness carryover (as Beerery was saying with the smoke).
Makes sense, washing slurry that was harvested from a hoppy brew/ beer will have residual hop oils still coating the cells. This might transfer unwanted flavors/ tannins into a clean beer like a blond Ale or sim.. regardless if washed.
I'll just wait till next week to brew and just buy 2 packs of wyeast 1318 and do shaken not stirred
Or plan next time to use washed slurry from a beer into a similar beer..
Example hoppy slurry to hoppy ale , stout to brown ale, etc...
Thanks everyone.. so much to learn. And great brewers on here to learn it from!
This sucks! LOL
though...now I gotta wait since my LHBS doesn't have 1318 in stock
Wanted to make the oatmeal stout and blond tomorrow morning, Sunday.
But can't use that hoppy 1318 yeast slurry in these brew's, since the slurry is from the hoppy pale ale that had 5oz of hopps thrown in , dry hopped.
I'll just brew next week! Did I say this sucks.. lol
