Quick Question Regarding Pitching Onto A Yeastcake...

[mwd]

I am keen to try re-pitching my next brew with a cup of slurry from the current one, however I can't do it all on the same day. What is the best way to store the slurry overnight? Obviously I will put it into a sterilised & covered jar or bottle, but should I put it in the fridge or will leaving it at ferment temp (18C) be okay?

If you are just leaving overnight it will be fine in a covered jar at room temperature. I use 440ml olive jars with screw caps to store my yeast slurry in the fridge and usually leave out to warm up for at least 4 hours before pitching to avoid shocking the yeast.
Have had yeast in the fridge for months and never had one fail to fire (so far).

Im thinking about pitching onto a US-05 yeast cake, I probably should consider some yeast washing as the previous brew was extensively cube and dry hopped, but if I dont wash cause Im pushed for time, am I likely to pick up some flavour from the hops in the trub or are they pretty much spent by this stage?

my method is to put it in the fridge, let it settle a bit, seperate from the trub and wash in cooled boiled water, and when you need it on brew day bring it out and let return to temps.

I now try and collect from the previous brew, and as I now have 2 going at a time a week apart I have plenty to wash at any given time (weekly botteling sessions)... now my problem is running out of bottles

I did do it all in one day the other week.. bottle, collect yeast and wash while I was brewing the next one.. it did turn into a mommoth 8 hour event so Im trying to not do it this way again.. must be said too that that brew was a 1050 wort and it was at 1010 7 days later!! Packet yeast (05) was always 2 weeks for me, pretty happy to get it down to a 2 week turn around!! :beerbang:

If pitching on to yeast cake make sure temperature is not too high when it takes off can produce a lot of heat .

personally I would wash it, but seeing as how people just throw it in on top, if a similar brew you should be fine.. never done this myself though... just doesnt feel right, I like to pitch cleaned yeast and no trub of hop debris.

thats Just me though :unsure: .... the nervous sort

It takes a few minutes to rinse your yeast, and that way you remove any hop or trub debris and have a good idea of exactly how much yeast you are re-pitching.

makes sense, I should wash the yeast,

besides, Cleanliness is next to Godliness, and beer is my God :icon_cheers:
