Notes

I generally hit the high attenuation end with Wyeast if I mash at 66 Deg (and even more for a cool beta rest). But here?

The BJCP style guide specifies an original gravity of 1.046-1.054 and final gravity of 1.010-1.015. I normally get 1.046->1.010, =79% for Alt. But to get that FG correctly predicted I need to set 93% custom attenuation?

BU/GU is 1 but about 25% from first wort Saaz, so that's perfectly drinkable.
