The most famous producer of black tea in the world is the island country of Sri Lanka, from where it is exported all over the world. The English, for example, are so popular with black tea that it has become their national drink (tea at five). Tea has a large spectrum of flavours, from the mildest to the strongest. People drink it mainly for its stimulating effects on the body. It also means great benefits for immunity and warms the body, so it is good to drink it especially in the colder months.
Black tea is probably the most widespread and well-known type of tea in the world. Unlike green, semi-green or white teas, black tea is allowed to wither by the action of the air flow during processing, i.e. oxidised. This gives it its characteristic black colour and distinctive taste.
