Use 1 rounded tsp (3 grams) per 8-16 oz of water, rinse leaves with 205° water for 4-8 seconds, discard rinse water. Then steep with 8 oz water at 205° for 8-20 seconds. Good for multiple steepings. Steeping for longer time periods will produce a progressively stronger cup.
The flavor of all Puer teas evolves over time. This is because during storage there are naturally occurring active micro-organisms in the leaf, that over time change the aroma and the flavor of the tea. All dark teas (including puer) can be wonderful when they are “young” that is less than 2 years old. Each year after that the flavor will get a little richer, deeper, more complex. Many people store dark teas, particularly puers, for years before drinking, because they really enjoy that more fully evolved, more complex, stronger flavor. So feel free to experiment with steeping times and storage times, to find the best method to get the flavor you want from your dark tea.
