Gone a bit wrong...

Post by drjim » Fri May 28, 2021 7:05 pm

So I made a fantastic batch of Boddingtons clone bitter using WHC saturated liquid Yeast, saved the yeast cake into some carefully sterilised jam jars (newly bought for the purpose). Then I made a couple of batches using the harvested yeast.

1 It was slow to start
2 It smelt normal during ferment
3 Temps were as usual, in cupboard under stairs.
4 It looked OK when I pulled it out of the FV
5 OG was about 1.042 FG about 1.006
6 It's in my 25L jerrycan kegs and..

It's cloudy
It tastes of TCP
I have 45 odd litres of it!

I did a batch of another beer yesterday with the same yeast harvest, so I've stuck a couple of crossmyloof ale yeast packs in there this morning and hopefully they will sort it out.

I suspect there will be a load of beer going down the drain.

Sounds like it could be infected (though there are other sources of TCP flavour - see here: viewtopic.php?t=79678#p825354 ).

Did you make a starter first or just chuck the contents of the jar in?

I just chucked it in, did similar with a previous harvest and it worked fine. The batch yesterday I did a pseudo starter with some part boiled wort, so hopefully that'll make a difference.

Gutted that I have two batches of rubbish beer, not had anything go wrong like this since going all grain. I also have a batch of my Aussie lager that tastes a bit like Castlemaine XXXX rather than what I was aiming for, that's a bit cloudy too...

Established yeast suppliers tend to be worth a punt, generally, as they know what they’re doing. WHC - trying to profiteer from Norwegian junk yeast - don’t strike me as having a feckin clue, tbh. That, and, to be perfectly frank, your crap procedure, what were you expecting, exactly, apart from the predictable?

That’s just me loosening up :D

With a slow start it sounds like an infection got going before your yeast did.

Problem resolved by use of drain. Both batches tasted odd. Hopefully the extra yeast will save the one I started yesterday and I'll hold off any more yeast harvest experiments for a while. Sadly I have loads of lagers underway, so all FV in use. Will be a few weeks without hand pulled beer. Consoling myself with a nice stout and have put some bottles from previous batches in the fridge.

It's a mixture of physics, biochemistry, microbiology and fun this brewing. All of those are experimental arts. Shame I learnt with this experiment. Previous batch made with a jar of salvaged yeast was actually the stout I am drinking now, guess I was lucky.
