I just got 82% on my last batch with S-04, went from 1.073 to 1.013. This was a Munich based beer that I mashed at 150 F for 65 minutes. A different batch before that got 78%. This is a good yeast. Unlike some other yeasts, this one drops crystal clear after a few days; however I do have a chill haze on the current batch, not sure why, it does clear as it warms.
Still no fruitiness, no diacetyl, no sulfur, nothing off. Very neutral, like you wish US-05 was but isn't.
