Matcha is a form of powdered green tea that traditionally played a part in the Japanese tea ceremony. It has recently started appearing in various drinks and desserts. It may also provide several health benefits.
Most people prepare green tea as an infusion. This means that they drink the hot water in which they have steeped the tea leaves.
On the other hand, manufacturers grind matcha tea into a powder and mix it with hot water. This means that a person drinking matcha tea consumes the powdered leaves.
