Hi all,

I put a lager on on Saturday just gone - S23 yeast @ 12 degrees. OG = 1052

Today it's sitting at 1022 and I expect it to finish at 1010/1012.

At what SG would you start a D-Rest? And what temp would you bring it up to 16/17?

All help greatly received.

Cheers
JD

Hey JD

I'd be making the move to 18 degrees about now.

Supposed to be when 80% done I think…

What the others said, I'd be allowing it to rise to 18C about now as well, which is my usual lager procedure. Leave it up there until a few days after reaching FG, then drop it down for a cold crash.

Thanks guys - I've increased the temp this morning.

I was surprised how quickly the S23 has chewed through the brew @ 12 degrees - 5 days from pitching to hit 1022. Is that normal? I was expecting it to be longer.

hey JD

5 days at 12C for S-23 to reach that gravity sounds about right. I did a recent ferment at 10C I think someone here recommended 10C for cleaner lager, so thought what the hell, try it). It took me about 6 days to get to 50% attenuation, but my OG was a bit lower at 1.047

In comparison, when I ferment at 12C it can get to 50% as early as 4 days in. I build up starters though, so don't have the lag time of dry/rehydrated yeast.
