Whole leaf tea is the highest grade of tea. It contains more catechins and antioxidants, and can be steeped multiple times. There are also -
Brokens, which are small-sized crushed leaves that are left over after producing whole leaf tea -
Fannings, which is inferior-grade tea made up of small particles and is often mass-produced -
Dust, which is the lowest grade tea that should be discarded as waste but is often used commercially by tea companies to reduce cost. It contains few natural benefits, and can be bitter in taste.
