How long for 05 to finish

[autonomist3k]

I brewed an ipa with an OG of 1.065 and used 1 packet of US-05, it's taken about 10 days to finish, maybe 11.
Is that unusual for 05, that's the longest It's taken out of all the beers I've made so far so I'm just curious.

I have a brown ale fermenting right now that I used 05 in and it's still bubbling away at day 10 for me too

I guess it's normal.
I should add that it's been sitting at the low 60's temperature wise.
One night got real cold and the fermometer said 59 for probably about 12 hours, but that's not reading the internal temperature.

Ya mine stays at 63 all the time with 05.

That's about as low a temperature as you will want to run that yeast. Make sure to raise it to 68 for a day if you can to do some cleanup. Should be a clean fermentation.

I agree with this, you can get a clean fermentation with 05 even if you are in the 65-68 range, plus it will finish a little faster. Too low and you can start to get a peachy flavor from it. Also, try to minimize temp swings. It will slow down considerably if you are at 63 and then it drops to 59 simply as a defense mechanism because yeast is very heat sensitive.
