Last three batches I brewed using US-05 has acted strange. My brews are generally pretty high gravity. I've been setting up my blow-offs expecting a violent fermentation. It hasn't happened. Rather, I was wondering if fermentation even started. It has been the same with all three brews. 3 days before I see airlock activity. Once I do see it, it is mild and slow. Activity lasts for about 3 days, very slow activity. Then nothing. Knowing that airlock activity does not equate fermentation activity, I waited two weeks before I opened up things and took a gravity reading.
In every case, the gravity reading showed 90% attenuation.
What is up with this? This is just blowing my mind. My equipment is tight. So is the accuracy of my tools. The only thing I'm doing different from what I have done in the past is that I'm actually pitching 3X as much viable yeast as I have typically done in the past with brews of equal gravity. I expected all hell to break loose. Instead I'm met with very mild fermentations with little CO2 activity. Is this normal? I've been brewing for a while and I've never seen US-05 act like this. Sure, it's a more mild fermenter than some other strains, but this is rediculous.
