Oh, yeah - freezing would probably work pretty well too. Say, three days
below zero degrees F, though some bugs are pretty hardy. (USDA and such
organizations probably have info published on this.) I just have so much
tea now that I'd have to find a walk-in freezer or run a lot of batches
through a big cabinet freezer.
