One Bulang cake, three cellars
This is the cleanest demonstration there is of what storage actually changes. In 2014 a single 2014 Bulang cake, pressed by a family workshop high above the Myanmar border from fierce, mineral maocha, was split at the source into three lots before any storage decision was made. One lot went to the Kunming facility. One travelled to the continental cellar, where winter cold and low humidity slow everything to a crawl. One went to the Foshan site, where the subtropical Pearl River delta air pushes fermentation hard and fast.
For a decade each lot has been tasted and its drift logged. The Kunming sample stayed bright and tightly wound, still holding a trace of its mountain youth. The continental sample underwent the slowest transformation of the three: velvet and resin, deepened by real seasonal freeze-thaw cycles rather than steady mild air. The Foshan sample is the most extreme, tasting a decade older than its years, all plum and camphor.
Same leaf, same picking day, same original hands at the wok. What separates these three cups is nothing but the storage decision made and then held to for ten years. Brewed side by side, it’s less a tasting than a demonstration: geography, humidity, and time, isolated and poured into three cups at once.
