Yeast at 10C

[jonohanson]

I have a rather large pantry which stays at a nice 10c due to its massive stone slab, I was wandering if there was a yeast(as I mainly brew lager) that could survive at this temp?

I have been keeping the current ones (supplied with kit) at the reccomended temps else where but was fancieing a change and to give true lagering a try.

Many Thanks.

10C is ideal for a lager, for brewing and then lagering after, Safale S-23 is a good dried lager yeast and will love that pantry. Go for it.

Cheers, will be ordering some for my crimbo lager, would it take longer to ferment at this temp or just be the usual 5-10 days?

Thanks

It'll take longer. For me lagers seem to take 10-14 days.

I've had S23 brewing Coopers Aussie Lager (with BE) in the garage since Friday 28 Nov at between 7.9C and 12.8 C - I get back to here with SG after a week - OG was 1042 - the cold approach inspired by this forum! Maybe its too cold (bloody weather) but experiment is good

I recommend the Czech Budejovice yeast from white labs if you can be bothered making big starters. If you can't, go for the dried yeast. I reckon the liquid is worth it though. My lagers take 10 days to ferment to completion at 10C.

Just taken SG of Aussie Lager - its 1022 after 7 days of really fairly low temps - looks to be fermenting steadily

Just keep checking the gravity, so long as its dropping its all good. The thing is even though the room temp might be low doesnt mean the beer temp is low. A volume of liquid is slower to lose its temp than air.

SG after 11 days 1014 - and its looking very nice - still fermenting away - Temperature has dropped to min of 6.5C max of 7.8C for last 3 days and I would say that the brew is at a temperature within those bounds - I understand that the temperature of the brew is unlikely to reach the extremes of the range, but they are representative - the FV is in a small cupboard insulated from air movement by blankets and the thermo probe is in there next to the FV and inside the blankets. I'd conclude that S23 works fine at low temperatures in this range

Well after 15 days where in the latter 3 or 4 days temperatures did not rise above 7.6C - the S23 has done its job and taken the brew down to a pinch above 1010 - so its now in bottles - temperature at bottling of the actual brew was 5.6C - I did not choose to raise the temperature at the end of the primary phase as I have read some do - I Think I'd like to preserve the diactyl content if it's there! I've primed with 4 grams of dextrose/pint and it's conditioning (is it still "lagering" with secondary sugar in place?) at ambient in the garage (currently about 7C) - I wonder how it'll turn out?

I'm thinking at least 4 weeks before I try it as sneak-preview and probably 8 weeks or longer anybody got any observations or suggestions?
