Definetely agree with good black tea in the morning. With Keemun you can even try to make let's say 'weaker' brew (3mins..?), when even not really expensive and high quality Keemun can have chocolate flavor and great taste..
With black teas (like DJ, Nepal, Kenya,..) you can try another way of preparation. Basic is about 4teaspoons of loose tea, wash it with cold water (in strainer,..) and put it in a teapot, in which was hot water for a while - so now you have a washed wet tea in warm environment, and immidiatelly you can smell the tea.. So be prepared to straight away pour just boiled water and you can start.. pour the tea from teapot into a cup from as high as you can ;o). Then pour the cup bach into a teapot. And do it again.. After a while you'll sea a foam on the top of the tea. When the foam is thick and 'solid' - tea is ready, just pour it through the strainer to get rid of the leaves..
As my informations are - the foam is caused by the saponins which are in the tea leaves as they are released by the brewing.
And what the pouring there and back does? Makes the tea colder, which is not the point
and mix or whisk the saponins, so it makes the foam - and the taste, especially with DJs is much brisker..
(Obviously, don't wait only for the foam to get thick - every tea makes it differently (green teas they don't almost do it) - every now and than just pour a bit in a cold cup and have a sip to try, it this is the taste you like..)
- and one more thing - this is really fast way to make great tasting tea in the morning
