Aged Pu-erh Cake

A disc of compressed dark leaf, wrapped in rice paper and stamped with the mark of its pressing house, this is tea meant to be measured in years rather than seasons. Break a piece free with a pu-erh knife rather than your fingers, working along the layers instead of against them, and you'll find the leaf inside darker still, almost black, with a scent of damp cellar, dried fruit, and old wood. Pu-erh is fermented, not merely oxidized, and that slow microbial transformation is what tea drinkers in Yunnan have long taken it for: a rich, settling cup poured after a heavy meal, valued for generations as a digestive companion at the close of dinner. The character it develops with age is the entire point of the leaf; where other teas are prized young, pu-erh is prized patient. This cake is a shou, or 'ripe,' pu-erh, pile-fermented to accelerate an aging process that raw pu-erh would otherwise take a decade to reach on its own, then pressed and rested a further several years before release. It comes from old-growth tea gardens in Yunnan's Xishuangbanna prefecture, where the leaf is picked from trees rather than shrubs. Each cake is dated, numbered, and tested for purity before it leaves the warehouse. Break off two or three grams, rinse briefly with a fast pour of boiling water to wake the leaf, discard that rinse, then steep in earnest for twenty to thirty seconds, extending the time with each pour that follows. It rewards a proper session: a gaiwan, a low table, nowhere else to be. Few teas ask so little and give back so much.
