You cannot reliably prove the age of Liu Bao from leaf color or taste alone; the most trustworthy assessment combines packaging, production information, provenance, storage history, physical condition, sensory characteristics, and seller transparency.
Liu Bao does not automatically get better with age; instead, good storage and time can transform it into a deeper, smoother, more complex tea, but whether an older Liu Bao is actually “better” depends on the original tea, storage history, and your personal preference.
