Heat retention while brewing tea: practical lessons
A small TeaDB experiment suggests that preheating and matching the vessel to the water volume can matter more than assuming one material always retains heat best.

Liu Bao is the signature dark tea (heicha) of Guangxi province, produced in Wuzhou City and named after the historical Liubao Township in Cangwu County. Like pu-erh, it is a microbially post-fermented tea — kill-green and first rolling, then heaping and moist fermentation, then second rolling and drying, followed by wet-piling and long aging. Records of Liu Bao consumption go back over 1,500 years; it was historically traded along routes from Guangxi to Guangdong, Hong Kong, Macau, and the Chinese diaspora communities of Malaysia and Singapore. Aged Liu Bao is prized for a distinctive "betel-nut aroma" (binglang xiang).
Fully-boiling water; rinse twice for older leaf to wake the aged storage flavour. Yixing or other thick-walled clay holds heat best.
Like pu-erh, Liu Bao continues to develop for decades under stable storage. Well-aged 1980s–1990s leaf shows the most pronounced betel-nut aromatic.
