So I have no problem calling some of these teas byproduct teas, because they were made while aiming to make Sencha or Gyokuro, or Matcha. This does not mean they are bad, or even sub standard, it just means it is not what they intended to make while aiming for the other teas.
adam,
it's not a question of good or bad. some lesser qualities teas are bad - a cooking matcha is not a good drinking tea, but it is perfect for cooking, it's intended use and very tasty - and some non-senchas are quite good. what i mean is we don't call oxygen a byproduct element. we are so used to the elements (we are less used to producing and to drinking tea) that oxygen, where ever it is derived from, is called oxygen. there is no byproduct section of the periodic table.
when you write "it just means it is not what they intended to make," it may not be always true that is what the producer wasn't trying to make. in fact some are intended. sencha or gyokuro is made from leaves or stems. is stem sencha or gyokuro byproduct tea? if not, why is bancha kikucha? what is happening is a tea grower sees the whole plant and knows what is best for what, and how to achieve it.
so my point is if you grow a tea plant to use the lower leaves for a bancha tea, or the twigs for a kukicha, or second or third harvests for tea - then this is not a byproduct.
especially since with sushi for example, you want a certain taste of tea to drink with it. and that wouldn't be a gyokuro. nor a shincha with greasy foods. these are intended produced teas that are drunk with those foods.
this is just my way to appreciate tea. i don't mean to drag on this discussion. to each their own, that's the magic of a small green leaf and hot water.
