This lot was produced using the steam fermentation method, which was a rare early experimental technique in the 1970s. The tea cakes are wrapped in thick cotton paper and feature large-sized character printing. The leaves used in this lot are coarser, and when brewed, they release a blend of camphor and medicinal scents. After aging for 50 years naturally, its aroma and flavor have continued to improve over time.
