Hi all - did my second (and very satisfying) AG brew this week, doing EdWort's famous HausAle. As it'd been almost 4 months since my last brew (another AG where I forgot to take an OG reading), I measured the OG pre-boil and was understandably concerned when it came out 1.027, when I was expecting in the neighborhood of 1.045. I threw in a couple of pounds of extra-light DME for good measure and the primary is rockin' away as I type.
Having come to my senses in the meantime and realizing I should've measured post-boil OG (d'oh), is there a means to convert pre-boil to post-boil OG? Of course I threw things off by tossing in the DME, but I'm still curious if I came close to the target.
6.75 gal of 1.027 --> 4.5 gal of 1.???
P.S. Thanks for the recipe & writeup, EdWort - all those Cascade hops smelled fantastic! My neighbor across the street said he could smell the boil from behind his house
