>>147You mean like bagged tea or loose tea? For loose tea, I recommend a good Assam you can get at your local grocer. If there's a place you know sells in bulk, get that. Assam has a taste similar to what you get in tea bags, so you'll have something familiar to start off with.
For bags, I don't know. I do know that you can improve the taste of bagged tea by brewing with water at 90-95C for 2-5 minutes and not torturing the bag to 'get all the flavor out' (I have seen people do this, and it's mortifying). Avoiding excessive heat, time, and pressure will minimize the bitter tannic flavor you get from a bad cup of tea.
