Just brewed my second batch. Both batches my original gravity have been significantly lower than they should be. Both batches are a extract kit. First was a American Pale Ale liquid malt extract kit. The one I brewed today is an imperial nut brown ale dry & liquid malt extract kit. I can't figure out why I can't get the original gravity correct. I've followed the directions to the T and have read a few different books to help guide me. My American Pale Ale was supposed to have an original gravity of 1.055 and ended up at 1.036 & this Nut Brown Ale was supposed to have an original gravity 1.075 and ended up at 1.034. I can't figure out what I'm doing wrong. Any help would be greatly appreciated.
