It's actually quite simple. Just put a few grains of barley in a little water and cook in a pot for about four or five minutes. The color is close to that of beer. I occasionally add salt or sugar to adjust my taste. Barley tea can be drunk hot, but it will taste better when it is cold. Especially drinking barley tea after sweating makes you feel more comfortable. This kind of tea has a special wheat flavor and tastes bitter and sweet. It is very popular in North Korea, South Korea and Japan. I also heard that barley tea is "plant gold". It tastes sweet, and has many functions, such as eliminating plague and detoxicating, invigorating spleen and losing weight, clearing away heat and diseases, moistening skin and blackening hair.
