FWIW...interesting.
Funny you should mention grass, because I purchased a premium brand of green
tea a while back that tasted like grass. It was plain old green tea in
fancy sealed pouches and it tasted like grass. I've tried lots of other
brands and they always tasted like tea, but this brand's green tea tasted
like grass while its green/white blend tasted normal. Is it possible that
batches of tea on the world market are adulterated with grass? I've seen
bags of fake marijuana buds made from grass clippings, so why wouldn't some
Chinese tea traders mix in a percentage of grass with tea leaves just like
other traders adulterate flour with melamine or toothpaste with antifreeze?
