Mugicha is a special kind of tea that is made from roasted barley. So, instead of using tea leaves from a tea plant, people use barley grains. The barley grains are first cleaned and then roasted until they turn a nice brown color. Then, they are crushed to release the crisp and nutty flavors. These crushed grains are then put into a tea filter bag or a teapot and hot water is poured over them. The result is a warm and comforting beverage that has a unique and delicious taste. The best part is that mugicha is caffeine-free, so you don't have to worry about getting too excited or jittery after drinking it. Mugicha is especially popular in Japan and Korea, where it is enjoyed both hot and cold. Overall, mugicha is a simple and tasty drink that can be enjoyed anytime and anywhere.
