OK, I know what you are all thinking, but I am a regular all-grain homebrewer and have conducted a lot of mashes. Lat weekend I made a recipe (from this database, in-fact) that used about 4# of base malt, 4.5 # of Maris Otter (more or less base malt, I know), a # of crystal, a # of vienna and a half-pound of carapils. With the exception of the maris otter all was left over and posed no problems in previous mashes. The maris otter was purchased in bulk from my local HBS store just days before brew-day.
Mash temps were in range nicely (154 F). (yes, yes, about 1.5 quarts per #, pH good) but after an hour it still looked unconverted, and iodine test confirmed this. Bottom line is it took 2.5 hours and almost didn't run off. Ultimately I got 70% efficiency when I usually get 80.
No sour grapes, the stuff is fermenting away as I write, but I really want to understand what went haywire and I can't figure it out unless the malt's diastatic power was lacking or non-existent.
What are the chances of something like that? I drank too much beer waiting for conversion and want to know how to do that again
