Crafted using a variety of ceramics techniques but left unglazed, a Yixing pot is able to withstand a higher temperature than glazed porcelains, making it the ideal choice for teas that demand a higher steeping temperature, such as oolong teas or black teas. Here's how to get started with your Yixing pot.

What we call "black tea" is known in much of Asia as "red tea"—referring more to the color in the cup than the blackened appearance of the fully oxidized leaves before brewing. It may also be useful to distinguish between the origins of black teas, such as Chinese (whose leaves are picked earlier and withstand more oxidation) and black teas of other origins, e.g. Africa, India and Sri Lanka (whose leaves are picked later and are less oxidized). The difference in processing methods of these teas is reflected in their flavor, and affects the way in which you may choose to brew them.
