Default End of fermentation temperature boost

Hi all,

I mentioned this in one of the many threads about fermentation temperatures last week, but I've been trying to get my FG down to my target gravity of 1.012 and many people have suggested increasing the temperature to get the yeast working.

I have a temperature controlled water bath which I turned up to ~20c (sits at 19.8c), and I took a gravity reading last night (it's at 1.02). The issue that the wort itself was 23c (73.4f). The yeast I used was safbrew t-58, which is "rated" up to 72f. I've since lowered the path temperature to 19c.

Is there a similar risk of fusels from having the temperature too high when I'm in the final leg of fermentation? Because if I don't have my bath warmer I don't see much fermentation. At the 20c water bath I was even seeing airlock action, which I was surprised about.

I started fermentation on 2/18 @ OG 1.072 and the gravity was stuck at 1.024 for a while (last reading at 1.024 was 2/26) and yesterday (3/4) the gravity was at 1.020, still having 0.008 to go.

The wort itself looks great and there is very little floating sediment / yeast on the top. It currently has a banana smell which I've come to expect, even in non-banana beers.


Any thoughts on this? Do you think the remaning .008 is attainable? Should I not worry about the 23c?

All grain or extract?

If all grain, 1.020 might be as low as you can get depending on your mash.

You aren't in danger of fusels at this point.

Extract, all grain starts this summer! So I'm safe to keep it at 23c inside?
