Fresh vs aged oolong

Most oolong is made to be drunk within a year. A minority is made to be kept for decades, and the two are not the same tea at different ages.

What is being compared

Why these get confused

Any old tea gets called aged. Ageing is a plan made before the tea is finished, not something that happens to tea that was not drunk.

Point by point

AspectTie Guan YinChen Xiang Tie Guan Yin
Intended lifeMonths. The floral aroma is the product and it fades.Decades, with periodic re-roasting to drive off absorbed moisture.
Oxidation and roastMinimal, to keep the aroma at maximum.Higher oxidation and heavy charcoal, which is what makes keeping it viable.
What happens over timeIt fades. There is nothing to develop into.Floral notes vanish and dried fruit, herbs and a thick sweetness replace them.
Is ageing passiveNot applicable — this tea is not aged.No. Neglected storage produces sourness; the re-roasting is maintenance, not optional.
StorageSealed, cold, and drunk soon.Sealed and dry, opened every few years for a light re-firing.

The short answer

A light oolong left in a cupboard for five years is not an aged oolong, it is a stale one. Ageing requires the right processing at the start and active maintenance after.
