Hello All,
I recently made a HERMS. I have used it twice and it has worked like a charm. Well I thought so until I had some of the beer that it created. It was very tanic and super dry. A classic problem of a low mash temp. The problem is that according to the reading from the probe on my control panel showed the correct temp. I am taking the reading where the wort comes back from the HERMS coil into the cooler mash tun. I did a test on my last run and put a thermometer in the middle of the mash and lo and behold it was a good 9 degrees cooler than the wort coming from the HERMS. What am I doing wrong?
