Help with S-04

[brewer_in_the_cap]

Hi all,

I've got 2 beers going with S-04 and I wonder if there's stuck fermentation or not. Both are NB extract kits, they had vigorous fermentation with blow-offs being needed for 24-36 hours. First one is the Brickwarmer Holiday Red brewed on Nov 18 and seems to be stuck or finished at 1.017 from 1.062. Second is the Dry Irish Stout brewed Dec 6 currently at 1.014 from 1.046. Ambient temp is 64 which might be a bit low. I stirred and swirled both but the gravity hasn't changed. Am I safe to bottle or is there anything I can do to move these down a few more points?

I'll be building a fermentation chamber in the new year.

Thanks and I hope everyone is having a great holiday!

1.017 and 1.014 are perfectly fine FGs for those beer styles. They've probably been done for a long time, since S04 is a very fast fermentor. They both probably finished within 48 hours or so of pitching.

Don't swirl it, as you risk oxidizing the finished beer.

Awesome, thanks for your help Yooper! Hopefully these will be bottled tomorrow!

I usually let the beer set in primary a couple weeks, but S-04 is a very quick strain and is usually done in about 3-4 days. I just started a beer about a week ago, an Imperial Irish Red concoction that clocked in at 1.076. Haven't taken a gravity sample yet, but it sure went crazy on it.

Thanks. I think I psyched myself out with too much forum reading! I use US-05 mainly and finish with a consistent 1.011 regardless of OG so these seemed high.

s-04 does finish higher that us-05. i use s-04 a lot, and i'd expect around 1.016 for a 1.062 og. you're good on the fg's. bottle, carb, cool, and enjoy

Stout bottled yesterday, Red should be bottled today! Thanks!
