My mother regularly uses 1 tea bag for two cups or 2 tea bags for a teapot. I've read on several sites that one tea bag is ideal for one cup.
So, how much should I get from a tea bag?
Also, is the steeping time different if I was trying to get more tea out of the same tea bag? Some say that steeping it longer gets more flavour out of the bag. Somewhat more formal research suggests that releases the bitter parts and makes the tea bitter rather than thicker.
I know you shouldn't reuse coffee beans when making an espresso, but does this apply to tea as well?
