The product of a tea producer specializing in Gushu sourcing, we've offered several of their Shu in the past, and keep returning for more. These cakes have had a few years to temper their bud-rich leaves, but they won't likely age much longer in our hands—there's only a couple on stock. The Pu'er enthusiast may also appreciate one of the producer's hallmarks: a simple wrapper embellished with a figure in a silk painting style. This one features the namesake bird and the tea's full title, "The Call of the Crane Over the Marshland".
