You don’t have to be a tea drinker to enjoy this warm film from documentary legend Les Blank. The passion and eloquence with which the tea connoisseurs interviewed here talk about the beverage is a delight in itself, a soul-nourishing reminder of what worlds of meaning and experience open up when you really love something. Though a few of these enthusiasts are featured — among them, filmmaker Werner Herzog —  it’s mainly centered around David Lee Hoffman, an American importer who swims against the tide of capitalism, mass production, and environmental damage to champion the hand-crafted teas he’s so passionate about. As the film chronicles, however, his insistence on buying directly from the boutique farmers — sometimes traveling hours into the remote Chinese countryside to do so — often puts him at odds with the economic interests of the big-time exporters he must work with.

Hoffman isn’t persistent in the face of all these hurdles for the sake of a buck, though: the film follows his linked efforts to encourage organic farming practices and a direct-from-the-source marketplace that will give the farmers a fair price for their hard work. That his love for the drink also encompasses the artisans who make it and the ground that grows it makes this an inspiring watch.
