I'm stumped guys. I have brewed about two dozen all grain batches, and every single time my efficiency is almost exactly 75% with my setup.
And then at random, yesterday my efficiency jumped to 80%. What gives?
My grain was crushed the same as always and I didn't stir it any more or less than usual. I did a few things differently this time but I'm not convinced any of them could have been responsible for the bump in efficiency.
1. I used Maris Otter for the first time (btw, this has to be the best smelling/tasting mash I have ever done).
2. I used reverse osmosis water coupled with mineral additions. I've done this for my last two brews too and they didn't have this efficiency boost.
3. I didn't use gypsum as one of the contributing minerals (ran out).
Other than that I really can't think of anything different whatsoever.
Atmospheric phenomenon?
