Hi all,
Just put a recipe together last night for an IPA. Based on the grain bill, both Pro-mash and Qbrew gave me the same #'s for OG and FG. I'm new to all-grain, this was my second AG batch, and 6th batch overall. After mashing at 155F for 60 min and sparging at 170F, everything looked good, so I took a pre-boil gravity reading, compensated for the temp, and ended up with 1.040. Figured it was alright, since a couple gallons was going to get boiled off, leaving me with 5 gallons. After the boil (90 min), I cooled the wort and got a reading of 1.042. Didn't seem right, and was WAY under what both software packages predicted, which was 1.069. I am thinking that there is some difference in what their #s are for extraction from the malt and what my malt actually did. I know there are a lot of variables, and I'm going to try and get a handle on more of them for next time. PH testing, closer control of mash/sparge water volumes, etc. In any case, the color was a beautiful copper, and as long as it tastes good it is good enough for me!
Any input on mistakes I could have made would be appreciated. Thanks all!
