The February issue of Food & Wine weighs in with a whole whopping paragraph about p'uerh (so what is the correct spelling, anyway?) teas with whopping price tags. It's right here. Don't wear yourself out trying to read it all in one sitting.
If it was up to me the p'uerh article would have been several pages and the piece on hoity-toity chef Joel Robuchon could have been reduced to a paragraph. Same for the thrilling report on "the comeback of carbs." But it may just be that I have a slight bias in favor of tea.
