US-05
« on: May 19, 2016, 02:25:36 pm »
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?

Of course that was my first thought.

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?

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.

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.

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

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
