I haven't made this in a while. I mustve still been using pellets last time a made it. It also looks like I was cleaning out the freezer for hops. I dont think the hops really matter here, just going for the right IBUs. This is the 4th iteration. I think on the 5th I'll use slightly less acid malt. Maybe 2 oz instead of 4. Efficiency was higher than normal too, the grain amounts are good for ~75%. I was messing with my new mill on this batch. My notes say I got a stuck sparge. :P

Is this the one I had at T'giving? I thought it was pretty good...in fact I brought a growler of it home.3 oz. of acid malt always seemed about right to me. I'd also 86 the protein rest and mash at 149-150. What else do you need to know?

Yea, it's that one. I was posting cause strangebrewer asked for it for his friend. I think the protein rest was troubleshooting a head problem that I've mostly narrowed down to a bad gas mix. I'll probably get rid the protein rest next time.

Anyone else think that 1.033 seems awfully low for potential yield on British 2-row?I am thinking this may be the reason your efficiency was "high"Looks like a nice stout, may do it soon.

Yea, it's 'spill a pint on your carpet good' if I don't say so myself.

Yeah, 1.033 does seem low. 1.036 - 1.038 would be more typical I think.

I may have used the default promash value, but I usually adjust it to what the brew store says on their containers or website. The MO I have now from Thomas Fawcett is 1.038.This brew session was the 2nd with my barley crusher. The first time I milled at the default gap. For this one I closed it to something crazy like .034 and got a stuck sparge. It may not be 91%, but it was higher than usual. I've made this recipe 4 times and usually aim for 5.x% abv and this one was above 6, maybe near 7. I'd have to look at my records at home to verify that though.
