Found a similar thread after posting this. Help with inexplicably low original gravity
Some good responses I need to look into. #1 would be stratification. I sampled post mash, after sparging, from the bottom, where the spigot on the Brewzilla is, without mixing the wort first.
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...
