earl grey without caffeine

Tea flavoured with bergamot orange aroma (citrus whose peel contains extraordinarily scented essential oil) is the first name in the world of flavoured teas. Its recipe originates in the end of the 18th Century, and was brought to Europe straight from China by the 2nd Earl of Grey, Charles Grey.
Tea leaves are treated with a special procedure using carbon dioxide to extract caffeine. Because chemical solvents are not used in the process, the tea retains its aroma.
