Often described as Crush, tear, curl (sometimes cut, tear, curl) 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.CTC is the acronym for Crush, Tear & Curl. It describes the factory process used to make the tea.The tea leaves are allowed to completely oxidise. Black tea is first withered to induce protein breakdown and reduce water content (68-77%) of original).The oxidation process takes between 4590 minutes[19] to 3 hours[13] and is done at high humidity between 30-37degreeCelsius.The processed black teas are further graded into different varieties in our factory.
