Brewed this last week and came away with surprisingly low gravity... which i recall reading other brewers experienced with this one? OG was temperature corrected to just 1.065, so i bumped it up with roughly a pound of buckwheat honey which brought it to 1.074. respectable for an RIS, but definitely not the 1.1+ prescribed by the recipe.
I'm putting this down to one or perhaps both of two things: first, this was a thinner mash than i'm used to. i went the full 1.5qrt to pounds of grain and so mashed in ~28qrts. Next time i would stick to my usual 1.25qrts to a pound. second, my mash temperature was slightly low? i forgot to preheat my tun and so lost a few more degrees than i had anticipated. Water was preheated to 176F but by the time it & the grain were all in the tun it had dropped down to under 149F, and i was shooting at 155F. Oh well. It still smells incredible and I'm sure will turn out delicious... just thought I'd report back. Anybody have any other theories? Generally my efficiencies are pretty good.
Also, successfully partigyled this and drew off a nice session porter. thinking i'll add some espresso to it? nice breakfast porter? Should be good.
