For sure. I still have some mainland Oolongs around I too bought some
6-7 years ago and they´re in amazing shape. Back to those dead
samples, one possible explanation would be some excessive moisture [>~
4-5%] those teas contained before I put them into my oh-so airtight
zircon-incrusted bags, since those bags had been stored under almost
ideal conditions.
What else is that tea afficionado supposed to carry on his travels ?
