Pitched a packet of US-05 into 5 gallons of 1.050 (an amber). 4 weeks later, FG is down to 1.025. This gives me an attenuation rate of like 40%. What could cause this? The first couple days of fermentation were really heavy; blowoff tube required and the whole bit.
The only thing I can think of is maybe my mash temperature was really high... I did notice that the temps were really uneven right before I started sparging; my notes say I was reading 140ish on the bottom of the tun and 160ish at the top, so if anything, that would put me well into the lower range, which should give me more fermentables, not less...
At any rate, it tastes great! So that's good news
