Black Tea methods of manufacturing and the varieties produced vary from country to country and region to region, but the process always involves four basic stages – withering, rolling oxidation and firing. This fully oxidized leaf represents tastes ranging from single estates and blends, to scented, flavoured and spiced. Research shows that Black Tea has a medicinal action that helps fight off tooth decay, sharpens concentration, lowers cholesterol, improves circulation may help prevent cancer and has a therapeutic effect on gastric and intestinal illnesses because of its tannins, which decrease intestinal activity. No wonder this variety of tea is the cornerstone of the tea drinker´s world.
