Yesterday during my mash I noticed something. I always poke my temperature probe into all different parts of the grain bed before I close the cover for the mash. Except yesterday I kept getting slightly different temperatures in different spots of the mash. I stirred more thinking that would fix it. But no, I couldn't get it all even. The temperatures were only off by a 1-2degrees. Target temperature was 151, and I got temps in spots from 149 to 153. I eventually gave up and figured it would even itself out.
Is this something normal or did something...funky...happen yesterday.
And yes, my thermometer is accurate. I ran some tests with it to make sure it was working properly after that happened.
