My favorites are Chun Mee, and Oolong both from China if you haven't figured it out already. However, the best everyday tea I've found in our local supermarket (the only market in our little town ~ Mio, MI) is Red Rose. There is an added advantage of buying Red Rose in the 100 bag boxes. Each box contains a ceramic figurine that are quite collectable for low budget collectors. Some of the older figurines will bring up to around $25. Several times the original cost of the tea. Hey, it beats the stock market!   

The current figures are endangered species.
