While I do a little bit of both, most large orders I place, focus primarily on teas that are less likely to become stale. These being Roasted oolongs, Black Teas, and of course Puerh Tea. While I say less likely to become stale, I do not mean you can abuse them with storage, I mean sunlight is still an enemy to tea, and so are strong aroma's.
But I did have the unfortunate happening of having roughly 40 grams of a Korean Green going bad. But due to the large amount of work I've had to do recently, I have been brewing tea a lot more in the lazy fashion. But I do not want to use premium leaf for this, I realized lazy brewed stale tea can sometimes be an improvement over brewing the stale tea in my typical fashion, ( a bit higher leaf to water ratio). While I still view this as a bit of a waste of tea, it certainly is much less of a waste than not drinking the tea at all.
So it seems sometimes a stale tea can have a bit of a second chance, as a tea to be consumed when you are busy doing other things and
