77 degrees F seems high.

My first RIS is fermenting. OG started @ 1.103. Pitched 2 packs re-hydrated S-05. Oxygenated with stone for one min.

Chris W and Jamil Z's yeast book says for high gravity beers, 12- 18 hrs after start of fermentation, add 2nd dose of oxygen.

I've done that.

It also says, "In 48 hours, after yeast growth is complete, raise temp to 77 degrees for ales. The rise in temp will keep yeast working at their maximum."

I've got the temp set at 68. I'm weary of raising it that high. I'm 48 hours in. Anybody think raising it that high is a good idea???

Thanks, Aaron

s-05 seems odd for a ris, but as for the temp, i wouldn't bother. i leave mine around 68

I raise the temperature when the krausen begins to drop. For ales this is usually from 68 to 72 over two days. For lagers from 48 to 60 over 6 days. I then hold for a couple of days or until I can keg.

Lots of ways to skin this cat though.

With 2 packs of rehydrated s05, 1.103 should be too tough. Don't overthink it.

It probably is good advice, from my understanding, most off flavours are created early in the fermentation, raising the temps later should only help clean it up.

s-05 seems odd for a ris

why?

I have a RIS currently sitting on US05, fermented around 64F. Got down from 1.107 to 1.032 in 10 days.

i just used a drill whip for about 5 minutes to oxygenate at pitching.
