Temperature Gauge Fluctuations
I was brewing the other day and my dial thermometer was giving out some crazy readings. I have a Bayou Classic 8 gallon brew kettle that I use as a mash tun, it has the thermometer built in. During my mash at 153, the dial would rise to 180 and then a few minutes later, go back to the actual temp of 153. During this time no flame was under the mash tun to even raise the temp. I have been using a newer digital thermometer too when I brew, and I checked when the dial read 180 with the digital and it read at 153. Has anyone else experienced anything similar? Do I have a defaulty thermometer?
