how many times can i repitch yeast

[wsmith1625]

something like this. Not sure but I think mine is a 200 micron. It catches a lot. my yeast cake harvests are very clean as a result

How long does it take to transfer using that? I imagine it slows down quite a bit after a layer of boil hops blocks the screen. I use one of these and it does let a lot pass through.

thanks for the replies this is turning into another good thread i love this site.
mac im right there with you id be staring at the kreusen too. im embarrassed to admit ive tasted kreusen more than once it looks so appealing... dont do that it doesnt taste good. mostly achingly bitter. lol
im up to pitch three on two of my current brews im planning to go to 5 or 6 with the yeast. now after reading this thread. i always was to afraid to repitch more than 3 times before.

i also use the tea strainers and a lot gets through and my cakes have a lot of hop in them thats why im looking into a better wort filtering method

thanks again everyone

I repitch until the refrigerated yeast fails the sniff test; like for socks or t-shirts (not underwear, NEVER underwear!!).

I take a pack of yeast, make a starter, pitch most and keep some for the next starter, repeat. At some point, it smells off, goes into the mulch bin, and I start over.

It depends on the type of yeast, the health of the previous batch and the storage time. Saison dry yeast that has not been kept for more than a week has worked best for me (zero wasting batch), but I do not exceed 5 - 6 generations, although I have a feeling that this yeast could do more. For example, US-05 make bad beer after the 2nd or 3rd generation under the same conditions.

hi
a little off topic but i am dry hopping a lager for the first time this week and wanted to just dump the hops in instead of hop sacking them. if i harvest this yeast cake after are the hops heavy enough that they will settle out or will my slurry be to full of hop particles for the next batch.

thanks

It's prowlly too late to help now but in the future. Most ale yeasts used for brews we dry hop have a very thick krausen and when lots of kettle or dry hopping I top crop it for next gen. The brown/green that's on top gets tossed and the tan cream saved. The only issue is I don't know the cell count so only one more ferment, I never give it another generation after that.

You will probably have some mixed in, I'm not sure if it's worth filtering out or if that's just going to introduce more potentially unwanted critters. When I do a heavy dry hop and want to re-use the cake, I just make sure I am doing a similar beer on top and call it good at two. I am nearing the end of fermentation on a hoppy Blonde Ale, a Rye IPA is going to go right on top once I keg it. The 4oz of dry hops for the Blonde will just add to the character of the IPA.
