Reusing lager yeast from a beer with clove flavour

[jceg316]

I'm making a rauchpils on Sunday and have a jar of S-23 I collected off a last batch which I was gonna put into a starter. The last beer I made with this yeast: the temperature fluctuated too wildly and there was a distinct clove flavour in the beer, a flavour which is due to stressed yeast. If I reuse this yeast will it depart the same clove flavour?

Probably won't carry over the off flavour, but you'll be pitching the same unhealthy yeast. I'd build up a starter from a small amount of the yeast you have, that way you'll be pitching healthy yeast.

Thanks, I thought so but wanted to check. Will make a starter. I will be making a starter for a wy-2124 Bohemian lager yeast for another beer I'm making Saturday (a very busy weekend!). It would be convenient to make a large starter and pour half in each, but don't think that is the right yeast for a rauchpils. I want the rauchpils to be quite dry and crisp which isn't typical of Czech pils, and probably easier to achieve with S-23.

I'm planning on a really dry American Pilsner with S-23 this weekend, with plenty of flaked maize in the grist.

Nice, good luck with it.

Turns out I couldn't make a starter with the leftover yeast anyway, I opened the jar in my fridge and there was a thick layer of mould! Never had that happen before.
