This weekend I brewed an IPA with an expected OG of 1.061. My post mash gravity was 1.053 (expected 1.054). Pre-boil and post-boil volumes (6.5G and 5.5G) were as expected. How did I end up with an OG of 1.056. I'm no scientist and relatively new at brewing but the boil evaporates the water... not sugar. So shouldn't I have been closer to the expected OG if my wort volume reduced as expected? I don't recall ever being this much off before if my mash gravity was right.
Additional notes: I'm using Beersmith for making recipe and calcs. Equipment is 35L Brewzilla.
All grain. Just 2 row and maris otter. No sugar additions.
This was the first time I milled grains at home and think I went a little to fine with a portion of the grist which led to some pump clogging. But got through the mash alright and was very close to the expected gravity at that point.
I used only a refractometer for checking my mash gravity. Checked it while hot (1.052) and retested when the sample had cooled, which was the 1.053 reading. Used the refractometer, a hydrometer, and tilt for OG (1.056). All 3 were the same for OG.
