Chou Yu, owner of the Wisteria tea house, points out that Yunnan locals really are not themselves in the habit of drinking aged Pu'er. Perhaps, when Yunnan's tea manufacture was still in the early stages of cottage industry, they developed the tradition of "selling the tea that grandfather grew." Later, as more professional tea manufacture developed, it changed into selling the tea as it was produced.
