I have a bitter hatred of magazines. My family has dozens of subscriptions and they can't seem to ever throw any of them away. Literally! I have to bag some up and toss them in a dumpster somewhere. Do they ever realize the magazines are gone? No! It's insanity! Issues aside, I did pick up a copy of Tea a Magazine and Tea Time the last time I went to Borders. Curiostiy trumps contempt every time.
For me, Tea Time (bimonthly) was a waste of money. There's hardly anything in there about tea! It's just china patterns, party ideas, and recipes for tea sandwiches, scones, and cakes. If that's your cup--you'd love it. If you want information about tea itself, move on.
Tea a Magazine (quarterly) is--thankfully--more about tea. Peter F. Goggi runs a Q&A column in every issue, the most recent on caffeine content in different teas. The winter 07 issue also has an article on translating Ukers' book All About Tea into Japanese, a nice photo piece on Shitoro Pottery, an article on tetsubins, and pieces on tea farms in China and the Glendale Estate (a spectacular article). They also include a few book reviews and highlight a few tea rooms of different aesthetics (one in an Asian bent which also caters to herbal supplements and such, one that is dripping in Victoriana, and another that is just pleasantly odd).
As a whole, the magazine isn't loaded with content--I had it read cover to cover in under an hour--but what they do have I did find interesting, decently written and definitely topical. I could see myself taking out a subscription...once I get over my pathological hatred of course.
