Compare two teas
Side by side across seven dimensions. There is no verdict and no winner — the purpose is to understand the difference, not to be told which to buy.
Why these two get confused
Both sold as wild or old-tree Yunnan black tea, and the terms are used loosely. Ye sheng refers to a botanically distinct purple-leafed population; gu shu refers to tree age, which is unverifiable.

| Cultural context | 'Gu shu' claims are the most abused in Yunnan tea. Tree age is not verifiable from the leaf and price is not proof. | 'Wild' is heavily overused on Yunnan labels. Genuine ye sheng material is limited and the purple leaf is visible in the wet leaf. |
| Who may prefer it | Someone who wants the cup to assert itself and has drunk enough tea to notice what changes between infusions. It rewards attention to leaf weight and timing. | Someone who wants presence without being dominated and is willing to drink something several times before it makes sense. It rewards attention to leaf weight and timing. |
Nothing above is a recommendation. The last row describes the drinker each tea suits, using each tea’s own authored fields and the same sentence structure for both, so neither can be framed as the safe choice.
