It definitely has some horsepower. How long are you going to age this big boy?
Single infusion?
Make an ESB and use the slurry.
Looks nice. Maybe hop it up a couple notches or… :-\
Oh no, it’s totally brewed… made it last Thursday. Used the slurry from a batch of English IPA (Buyer’s remorese)
And it gets at least 6 months age.
It will be a good one. 
Looks awesome Drew, I should have done something similar. Maybe I’ll need to do a 26 year beer, cut it down to 52 lbs of Maris Otter 
damn, when you have to break into a second bag of grain to complete your grain bill for a single ingredient; then you KNOW you’re not messing around. Why the 90min mash? Just to make sure that massive grain bill is fully converted?
Mark,
Yeah, I mashed long since it was a super thick mash and I was mucking with water levels in it to deal with the massive level of water absorption.
It’s really sad that a few months back I bought 110 lbs of MO and after two batches, I’m almost out. blah
How many free (second and third runnings) beers did you get? It would be a shame to throw away all that potential extract.
