Not really a question, just sharing my befuddlement.
Gravity was constant for 10 days.
I had mashed on the hot side (157 F) and gotten a 50% attenuation and was pleased that I'd have a lower-alcohol, higher-body beer. Now it's at 70% attenuation and still going down.
I suppose a diastatic yeast could have gotten in there somewhere. Or that it's Tilt weirdness. I'm going to wait until it stops and keg it. It'll turn out how it turns out.
