hi everyone, I have a helles extract beer kit I’m about to start making, the yeast it comes with work’s best at around 18-20c, but my basement is around 15/16c, does anyone have a recommendation for a yeast that I could use that would be better suited to the ambient temperature? I do have a basic immersion heater, but that seems to heat the liquid to around 22c
 
Great, thanks. I’m assuming it will take a lot longer than the 2 weeks listed on the kit? If I ferment the provided packet of yeast (M54) at around 22c instead of the recommended 18-20c, do you expect it will have a significant adverse effect?
 
If you increase the temp you'll increase esters, so the beer may not be as clean as you want. Another thing, if you're fermenting at 15C/16C It's advisable to double the amount of yeast
 
I have no temperature control so I guess I ferment at anywhere between 12c and 22c. At the very low ends, I wrap an old beach towel around the fermenter.

I would use the kit yeast (as it is MJ rather than just a random silver packet) but expect it to take nearly 3 weeks to fully ferment
