Specialty & other origins
Oolongs that fall outside the four major geographic families and serve different purposes. GABA Oolong (from Taiwan or Japan) is produced under nitrogen atmosphere to elevate GABA content and has a distinctive fruity, almost wine-like character quite unlike conventional oolong. Zhangping Shui Xian from Fujian is pressed into small cakes rather than rolled or strip-shaped. Vietnamese oolong from Lam Dong province is a smaller but genuine tradition. Aged oolongs — typically Wuyi or Taiwanese material stored for years or decades — develop an entirely different profile from the young versions. These are the teas for collectors who have worked through the major families.
