Gongmei vs. Shoumei: cultivar rule vs. trade usage
Under GB/T 22291-2017, Gongmei must come from seed-grown group bushes. Shoumei may come from Dabai, Shuixian or group bushes, and from shoots or leaves. Leafy tea from clonal Dabai does not meet that standard’s Gongmei product definition. In the trade, Gongmei is still often described as the better grade of Shoumei. A 2020 explainer notes that Gongmei made from caicha is now a small niche.
