US-05

Ingredients
1

I really don’t use dry yeast all that much.  This year I did.  I made four batches with US-05 and every single one was over carbonated.  When I noticed this on the first batch I reduced my priming sugar from 3 oz. of cane sugar to 2 oz. and still over carbonated.  No sign of infection on the neck of the bottle or off taste.  Is this typical with this strain.  I cracked the caps on all the bottles and now they seem fine.

This sound familiar to anyone?

Nope, I don’t think that’s anything you can attribute to that yeast.

First thought: are you certain you are at terminal gravity when you bottle, i.e., same FG 2-3 days apart?

4

Of course that was my first thought.
OG: 1.044  FG:1.008  14 day primary  29 day condition
OG: 1.063  FG:1.012  9 day primary  22 day condition
OG: 1.058  FG:1.010  12 day primary  31 day condition
OG: 1.058  FG:1.012  9 day primary  35 day condition

It looks like the longer you primary, the lower your FG. I wouldn’t expect US-05 to go super dry. I’m wondering if there isn’t infection at play here pre-bottling?

6

FWIW, I use a long primary for most beers and 1.009-1.012 FG is pretty standard for me using 1056/S-05, depending on what I’m brewing.

Edit - 1056/S-05 are pretty dry strains IMO. I like well attenuated beers normally, and have to intervene with grist to finish much above the listed. Obviously stouts and others with higher amounts of unfermentables are a different story.

7

If there were an infection wouldn’t I see some evidence on the collar of the bottles?  Also, the carbonation would continue even after I cracked the caps to release some of the pressure. It doesn’t.

8

Only four possible answers. Not finished fermenting, infected, busted scale, priming sugar not well distributed.

9

Not necessarily on either of those.

My experiences with 05 are that it finishes a lot dryer than I expect. I have gotten anywhere from 79% to 82% ADF with it, even on high gravity beers. My last batch with it was a 1.098 double brown that 2 re-hydrated packs took from that 1.098 down to 1.020, 78% ADF, and IPAs with it have run up into 82%. This does not say yours were not finished, just that it seems to outperform software and manufacturer expectations every time I use it. I have not experienced over carbing that I could attribute to the yeast itself, just improper weights and volume measurements on my part
