I used to buy leaf tea in regular grocery stores in Russia. You know, on one side there are tea bags, on the other side there leaf boxes. It was some kind of surprise here in Canadian groceries to find tea bags only. No weighed, no loose tea. Don’t know why.
If you will ask me what’s the difference, I’ll hit you in your face with my fist. Really. This is obvious. Bag tea is not a tea indeed, it is a sawdust with artificial aroma. Technically, tea bags are made of a waste which comes out of normal tea making process. I drink that sawdust too, so as instant coffe — when I’m in hurry or too lazy. But they are two different kind of beverages.
