This has been bugging me for a while. Once upon a time, years and years ago when I was first delving into tea, I bought a teapot at a moving sale, and she threw in some tea. It was super fragrant-type tea, but it was all in ziplocks, and the smell was completely gone.
Paid notice for a while and figure out that ziplocks, and other plastics, kill the smell and flavor, sometimes replacing it with a plastic smell.
But in the last year or two I have been noticing lots of tea shops dolling out tea in plastic bags, which I pass off as just temp housing til we get our goods home, but also a lot of puerh shops keep their sample cakes in plastic bags, even ziplocks. Legit dealers even. I got a sample of some 98 sheng today in a bag with a thick plastic front.
So what's up with all that? Some plastic ok, others not? Any ideas?
