Dark tea should be brewed with boiling water. You can use purple clay pots, covered bowls, or porcelain pots. It is best to boil water in a cast iron pot, as it can heat water to 100°C, helping to bring out the flavor of dark tea. When brewing, first chop the tea, take an appropriate amount and put it into the pot, rinse the tea, then boil. For the first infusion, steep for 30 seconds to 1 minute; for subsequent infusions, add 20 seconds each time. It can be brewed multiple times. Aged tea is more resilient and can generally be infused more than ten times.

Characteristics of aged dark tea: The liquor is bright red and clear, without sediment or turbidity, resembling aged foreign wine, highly ornamental, and best brewed in glassware for color observation. The first infusion tastes sweet, smooth, and mellow, rich but not greasy, with a slightly sour aftertaste. The middle infusions are sweet and refreshing, melting in the mouth. Later infusions, even as the color fades, still taste sweet and pure, without off-flavors. The aroma of the first infusion is mellow and aged, with mild intensity; the middle infusions combine aged and mellow notes; later infusions highlight the aged aroma, with the mellow scent fading.
