ok so today i plan on doing a single step infusion mash with 14 qt h20 and 11.75 lbs grain (1.2 qt/lbs)
Usually for the mash out i add enough boiling water to raise the temp to 170. But for this batch i want to try using a decoction instead. Im basing my technique on an article i found on this site.
So after 60 min @ 150F im going to remove 4.5 lbs of grain and enough wort to create an oatmeal like thickness. (40 percent would be 4.7 lbs, which is supposed to raise the temp by 28 degrees, im using 4.5 because its easier to measure and i dont need 28 dgrees, just 20) Im adding this to a cold kettle and slowly bringing it to a boil, stirring constantly. I boil for ten minutes then return to mash tun. If the decoction gets too dry i add some more liquid wort.
My questions are these:
1) Is this a sound technique?
2) should i weigh the decoction, or just eye-ball it using 1 qt= 1 lbs of grain estimate?
