Automatic warming wine tank

Developed in Japan, it is suitable for heating wine (similar to our country's rice wine). There is a mezzanine at 1/5 below the canister, which contains quicklime and a small bag of water sealed in a plastic film. When drinking, only one “suitable” plastic stick is used to break in from the lower water hole. The water reacts to produce heat, which warms the sake to 58°C. After 3 minutes, the sake can be hot-drinked, which is very convenient.
