Black tea

TeaHQ has written about this pair

Three teas sold as Yunnan black tea at three very different prices, separated by claims about the trees they came from. Two of those claims are unverifiable by a buyer and one of them is visible in the leaf, and the practical question is which differences you can actually detect.

What the plant material is
Dian Hong: Cultivated plantation bushes of large-leaf assamica, the ordinary Yunnan stock.Gu Shu black tea: Old-arbour trees, the same material whose leaf usually becomes sheng pu-erh.
What the claim rests on
Dian Hong: Nothing contested. This is the default and nobody charges a premium for it.Gu Shu black tea: Tree age, which no buyer can check and no certificate establishes.
What it tastes like
Dian Hong: Sweet potato, cocoa, malt and dried longan — round, sweet, almost no grip.Gu Shu black tea: Honey, wet stone, dried fruit and camphor, with a long mineral finish.
What is detectable without being told
Dian Hong: Nothing to detect; it is the reference.Gu Shu black tea: More weight and a longer finish than plantation material, which is real but is also what a well-made plantation tea can approach.
Where the premium is safest
Dian Hong: No premium.Gu Shu black tea: Weakest of the three. An old-tree claim on a black tea is the least checkable and most freely made claim in Yunnan.
How to brew it
Dian Hong: Boiling water, western or gongfu, and it is forgiving.Gu Shu black tea: Slightly cooler than boiling and short, or the weight turns heavy.
The naming risk
Dian Hong: Dian Hong covers everything from commodity to speciality under one name.Gu Shu black tea: Gu shu, old arbour and old tree are used interchangeably and none is defined.

In summary: Buy the wild-arbour tea for the flavour, which is genuinely unlike anything else Yunnan makes and is worth its price on the cup alone. Judge an old-tree black tea by tasting it rather than by its claim: some are outstanding, the claim behind them cannot be checked, and a good plantation Dian Hong at a quarter of the price is a serious competitor.

Cultural contextBud content drives the price, and 'golden tips' grades vary enormously in how much bud is actually present. A high proportion of gold in the dry leaf is visible, and is the one quality signal a buyer can check without brewing it.'Gu shu' claims are the most abused in Yunnan tea. Tree age is not verifiable from the leaf and price is not proof.
Who may prefer itSomeone who wants presence without being dominated and wants to enjoy it on the first cup. It tolerates an imprecise brew and is traditionally drunk plain.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.

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.
