Google “black butte clone cybi.”
They get the recipe straight from the brewer. I’ve brewed it twice and it’s spot on.
I got the chance (through my job) to sit down with a retired QA mgr from Coors. (Yeah, yeah… These guys are at the top of their industry scientifically)
He offered to taste it for me, so the next day I brought him a bottle. Without looking at my notes, he was able to nearly tell me the exact grain bill, hop origin, ibu, srm, abv. Insanely impressive.
Without being polite, he said the beer could easily be a high selling commercial example.
That recipe is pretty solid. Just make sure to use the proper lovibond chocolate malt.
