FG stuck at 1.020 and it's time to bottle.. will it carb?

[82cabby]

Hi all!

I have a batch of 115th IPA which has leveled off at a FG of 1.020 after 3 weeks in the primary and 4 weeks in the secondary. I would like to bottle it, but have two questions:

1) I am afraid of low carbonization when I bottle condition. Do I need to add yeast at the bottling stage? I am worried that since the beer has leveled off at 1.020, the yeast might need re-vitalization.

2) I am down to roughly 4.25 gallons in a 5 gallon batch. I lost a lot from primary to secondary due to all the dead yeast and hops. Is it ok to add a little volume back with the priming sugar? I'm thinking maybe 1/4 to 1/2 gallon.

Thanks in advance for your help!

The fermentation probably stalled because the yeast ran out of fermentables, not because of a problem with the yeast themselves. Just adding priming sugar will be fine.

Do you mean adding water to make up the volume? Then you will be diluting your beer. The only way you could do this properly would be to brew a small volume of the original beer and blend the two. I would just live with the lower volume.

And I shouldn't have probably said the fermentation stalled, in my last post. Depending on a variety of factors, 1.020 could be a perfect place for the beer to finish.

A lot of my batches only get down to the 1.020 level and I just bottle them anyway. They turn out fine and my IPA has been excellent.

Here's some reading on the '1.020 curse': https://www.homebrewtalk.com/f37/1-020-curse-63896/
Some points look like it could be caramelization or calibration of the hydrometer at different temperatures giving a possible error of up to .010.

Cool, thanks everyone. I'll bottle it and not worry.

What's the OG and what was your target FG? 1.020 isn't necessarily a bad thing. If it comes out sweet just pitch more yeast or use a starter next time. It'll dry out the sweetness and raise the ABV a little

Check the accuracy of your hydrometer. Boil some water, chill to 59, and dunk it. I had what I thought was a stalled ferment, that turned out to be a hydrometer off by .002.
