An important part of serving a great coffee is the consistency in milk temperature. The accuracy of the Temptag allows the barista to serve coffee at a perfect temperature every time. Unlike traditional thermometers, Temptags have no direct contact with milk as they’re applied to the outside of the milk jug eliminating the possibility of cross contamination as well as promoting hygiene. When using the Temptags you’ll never need to worry about calibration like traditional thermometers. Temptags are easy to read, hygienic and have great accuracy.
