TempTag is exactly what it says it is: a temperature-reading tag. Temptag began as a start-up store in 2009 in Melbourne, which is widely regarded as the spiritual birthplace of Australian coffee. Their one-of-a-kind product helped them to swiftly expand, and they now trade all over the world. Their attachable milk jug thermometers are a game-changer, allowing Baristas to regularly and hygienically monitor the temperature of their milk. The Australian Made Campaign has officially recognised Temptag as an Australian Made product. Of course, the conventional thermometer is still a helpful instrument, but it must be cleaned on a regular basis to maintain cleanliness and prevent cross-contamination because it is placed in the milk. Baristas may spend less time cleaning and more time brewing delicious coffee with Temptags external stick-on thermometers. Temp tag is now selling a selection of milk bottles with the technology pre-installed, ensuring that quality is not compromised. Unlike certain traditional thermometers, they also do not require calibration. Temptag works with a variety of local universities, barista training institutes, and TAFE institutions to teach and train students about coffee.
