I hates 'em, I hates the blighters!
Damnnit!
AAAAaarrrrgh! The bane of my existence!
I calibrate the ones I can (insta-read probe type) but still they lie! I adjust boiling point for elevation and barometric pressure with a boiling point calculator.
I also calibrate at the other end with crushed ice and water in a glass to set the freezing point. Still they are farkin' farked!
I bought a lab type "calibration" spirit thermometer from More Beer. Assumed it was accurate and used that for a while. Checked it on a whim yesterday before brewing. In boiling water it only reads 204F!!! The current boiling point yesterday at my elevation and the barometric pressure was 210.5F. In freezing water it was like 34F!?!
What the HELL! So I used 6 thermometers in my mash. How many different reading do you think I had?
That's right 6! With about a 10 degree variance!
If I cannot trust a lab thermometer which is supposed to be used for calibrating others what can I trust?
Smegging hell! I think they were perhaps better off in the days before thermometers!
