It is unconventional to blend Keemun, a black tea, with Oolong tea, because Oolong steeps better in water that is below boiling.
I prepared this tea with a pre-heated teapot and boiling water, and it turned out to be really good. It is an unusually interesting tea, earthy, sweet and slightly spicy, starting strong and finishing smooth and mellow. It makes a dark orange liquor, does not need to be brewed any longer than three minutes, and has a very appreciable flavor without milk or anything else added. It has no bitterness at all.
A very good tea. Save it for when you have time to drink it slowly and enjoy the flavor.
