I've been hitting between 80-84% efficiency, and overshooting the crap out of my OG. Most recipes are aimed at 70% efficiency, and my ABV has of course been way higher than expected due to better sugar conversion in the mash. Should I cut back my grain bill? modify my crush? I feel pretty dumb for asking, because it seems pretty logical to just cut back the grain bill, but everyone gets so excited about high efficiency, so I'm not sure if I should just leave it alone, or what?!

It's early and I'm still working on my first cup of coffee, thus the rambling.

Primary - Bluebird Bitter, Negra Modelo
Secondary - Flanders Red
Drinking - Independence Pale Ale V1.0, Trappist Style Dubbel, Dunkelweizen, Saison, Fat Tire, SNPA
Conditioning - Chimay Red, Imperial American Pale Ale, Independence Pale Ale V2.0, Belgian Wit
Kegged - Bluebird Bitter

The excitement of high efficiency is precisely because you can cut back on your grain bill and still acheive the desired OG. I just enter any recipe into beer tools pro with the efficiency set at the author's assumption, then I scale the ingredients based on my known efficiency.

Well, if you're following someone else's recipe (like in BYO- I think they are set up for 70% efficiency), and you want to hit the OG and the IBUs they have, then yes, just adjust the grain bill. I do that with others' recipes, but my efficiency is bad, so I have to adjust my grains UP!
