Black tea is fully oxidised and displays rich deep flavours.  Unfortunately most of the black tea grown and produced each year is low grade and destined for the tea bag market.  With premium loose leaf black tea you get more depth of flavour and complexity with lots of varieties best enjoyed without milk to fully appreciate their qualities.  Highly quality teas from Assam and Darjeeling in India are some of the most prized and sought after teas in the world.
