So I brewed a pale ale this week. I've used this recipe about four times. Got the same efficiency every time.
I calibrated my refractometer after the last brew session, and assumed that it would still be calibrated two weeks later. I took a refractometer reading after my first runnings, and it was a little low. I took another reading preboil and I was 6 points low. I took another reading. Same thing.
I accepted my fate and measured out some DME before I started the boil. Threw in the DME and followed the recipe through the boil.
I finished cooling and took a hydrometer sample.
It was 6 points high.
I grabbed some distilled water and sure enough, the refractometer was blue almost all the way to the bottom of the viewer.
I will be calibrating my refractometer before every brew day from now on. And every time that I am getting an unexpected reading.
