Assam CTC is a machine-made Assam black tea that is processed via the Crush-Tear-Curl method. These leaves are usually fully oxidized and make for a warm, full, amber-coloured cup of tea with bitter, malty tasting notes and sweet, nutty undertones. What is CTC tea? The full form of CTC is crush, tear, and curl. It is a processing method where black tea leaves are passed through a series of cylindrical rollers that have hundreds of sharp teeth that crush, tear, and curl the tea into small, hard pellets. CTC teas also have grades depending on the tea leaf. Black tea manufacturing is normally carried out in two ways, (i) CTC and (ii) orthodox. CTC refers to the Crush, Tear & Curl process where the withered green leaves are passed in-between two rollers rotating in opposite directions.27 May 2023
