Black tea is produced from the fully oxidized leaves of Camellia Sinensis, and black tea becomes Earl Grey tea when flavored with bergamot oil. Earl Grey tea is called “tomurcuk (bud) tea” in Turkish, and this leads to a common misunderstanding that this kind of tea is made with tea buds. However, Earl Grey tea or tomurcuk tea consists of regular black tea leaves only flavored with bergamot oil.
