Everything from brewing coffee comes from extraction, and water temperature is one of the important factors affecting the extraction of coffee powder. Water with too high a temperature causes excessive extraction during brewing of coffee, and too low a temperature tends to cause insufficient extraction. Therefore, every barista who requires precision will always care about the water temperature in the pot, and the water temperature of 85-92 degrees Celsius is recognized as the most recommended coffee brewing temperature. TOAST understands the baristries' strict requirements for precise temperature and launches a HAND hand-washing pot with a thermometer at the end of 2017. Compared with the general thermometer in the market, it is more suitable for large-capacity slimming body. The surface of the thermometer was redesigned by TOAST's own team, which is minimalist, easy to interpret, and has a common temperature range of 85-95 degrees in red. The thermometer is steam-proof and can be embedded in a wooden lid. The design of the body of the hand-washing pot can meet the strict requirements of the barista for temperature, and does not affect the aesthetic appearance. It is a new generation of hand-washing pots with both practicality and texture.
