Brewed an ESB a while back, racked it to a keg last night and checked the FG, which was 1.008 (expecting around 1.014). Fullers strain, 1.5L starter pitched at 18 hours. With an SG of 1.059, that's approx 87% attenuation and 6.8% ABV....
I've used 002 a fair amount and never had it go this low. The beer tasted clean, a touch boozy but it's green yet. Zero off flavors I can detect, anyway. Decent mouthfeel, didn't seem overly dry.
I'm not sure where to start, my refractometer, hydrometer or all of my thermometers. I mashed at 154, but even if I was off by 10 degrees low, I wouldnt think 002 would go 87%. My beers all attenuate well, but somethins funky here.
