Ok to bottle/barrel at 1008?

[ChrisG]

My IPA has been on the go for 8 days now using S04 yeast and its been at a steady 1008 for three days.

Using the Hydrometer Temperature Correction it would be 1009.

Not sure if I should just leave it a bit longer?

Really want to get another on the go not decided which yet, but a lager in a few weeks. May be a dark ale....mmmm.

Cheers

What OG did it start at? S-04 ferments down about 70-75% for me. Sounds good to bottle.

Started at 1038

How do I work out 75 % of my OG?

[SiHoltye]

Get in there! Well done you, I would suggest bottling it and cracking on with your next brew .

As I reckon on 75% for S-04 in a regular strength brew, multiply your OG by 0.25 (the remaining fraction of 1 after taking off the 0.75 attenuation figure)

38 x 0.25 = 9.5, or 1.0095, this is your anticipatd final gravity. Your under that and stable for 24hrs minimum.

It would be surprising if the yeast had any fermenting left to do so I think it's safe to bottle in this case. There are better explanations elsewhere and there are other variables involved sometimes but so long as you haven't added dry beer enzyme (which might take it even lower) you have fermented that brew out, congrats.

Thanks for the detailed explanation, that has helped a lot.

Gonna save that info, very helpful.

Looks like a job for the week end or tomorrow night then.

Whoohho!!

I can also answer your specific question.....sorry .

If your OG was 1.038. Simply -1 or ignore the first part of the number so you have 38, multiply that figure by 0.75 to give you 28.5. Put the 1 back on and the gravity the yeast will convert is 1.0285.

To work out anticipated FG take that from your OG and you have 1.0095, your anticipated FG based on 75% attenuation.
