CTC Dust Tea actually refers to a method of processing black tea. This CTC method is different from standard tea manufacturing, in which the tea leaves are simply rolled into strips. Crush, tear, is a method of processing black tea in which the leaves are passed through a series of cylindrical rollers with hundreds of sharp teeth that crush, tear, and curl the tea into small, hard pellets. This replaces the final stage of orthodox tea manufacture, in which the leaves are rolled into strips. Tea produced using this method is generally called CTC
tea or mamri tea.
