---------> I agree. Lipton has actually sold loose tea for many, many years BTW but the vast majority of the tea they sell is bagged. Fannings and "dust" are used because they infuse more quickly, and because anything larger does not have sufficient room to expand in a standard tea bag.
Many commercial blends that are sold as loose tea are CTC and some are only about a notch above being dust. Again, these teas were designed to infuse more quickly than whole leaves, and to be more affordable to the masses. They are not bad teas, per se. Personally, I don't like using loose tea that is too dusty because it is too fine for the strainer to catch it all. But I have also had very expensive loose tea made from whole leaves that I did not feel was worth the price. In some cases I actually preferred the CTC or even the bagged teas.
I also like high-quality tea but could not possibly afford to drink it exclusively, given the large quantities of tea that I consume every day. I like Taylors and Twinings, which some look down upon, but there is a limit to how much I can afford to spend on tea. I also like the fact that these teas are blended for consistency. It's a great comfort knowing exactly what to expect from a particular tea. Besides, the Queen drinks Twinings and if it is good enough for her, it is good enough for me.
I also like what many would deem to be "lower quality" teas sold in supermarkets. I don't like Lipton (there's nothing wrong with it, I just don't happen to care for it), but at work I drink Tetley British Blend all day long. And at home I drink more PG Tips than anything else. My main complaint about teas sold in the supermarket is not their quality, but that I can't brew them as strong as I would like. I cannot get enough flavor out of any 2-gram string & tag tea bag, which is why I stick with Tetley British Blend and teas imported from the UK that have more tea per bag.
