Depends on what you mean by best. Short answer is you need to define what is best for you and your style of learning. I have a similar background, my mother is Chinese, was born and raised in Taiwan and learnt Mandarin conversationally through her and in secondary school.

If you're talking about loose-leaf tea that has been properly stored (in a dry area), then no. Tea starts to break down and lose flavor, but it generally does not spoil. If you have tea that has been stored for a very long time, it will often taste very bland, and it may develop off aromas. But it is generally not harmful, unless it has been stored improperly (such as in too damp an area) and has grown mold.
