Matcha is a powdered green tea made not by steeping, but by mixing finely ground green tea leaves with hot water using a bamboo whisk. Ceremonial grade matcha tea is the basis of the traditional Japanese tea ceremony, though other grades are becoming more popular for use in things like matcha lattes and matcha ice cream. Matcha has also been linked to lowered blood pressure and lowered risk of heart disease. Go more into detail on matcha with our handy Beginner's Guide to Matcha Tea.
