We love tea. We like oolong but prefer black teas; e.g., oolong is a partially oxidized tea whereas black teas are fully oxidized. Black teas are known as "red" teas in China because of the tea's deep reddish color. Assam, Keemun, and Darjeeling are black teas.
Our favorite is Lapsang Souchong, which can be found in both green (unoxidized) and black teas. We like it very smoky and strong, so we are currently blending two different teas to our taste. Our blend comes out like a Russian Caravan tea that we are no longer able to obtain as the vendor went out of business.
The one black tea I don't care for is Pu-erh. It's fermented as well as oxidized, and to me it tastes like really bad coffee, LOL.
I also like white teas, but they are expensive and finicky to make. These are the teas you should measure both leaves and water, as well as heating the water to a precise temperature and steeping for a specific time. White Peony and Champagne Peony are really amazing to drink - very subtle, mellow, beautiful flavors. If oversteeped they can become quite bitter.
Oolong is the traditional tea served in Chinese restaurants as the default choice. Often Jasmine is also available.
