Is dark tea the same as pu-erh?
*Shú pǔ'ěr* belongs to the dark tea family. *Shēng pǔ'ěr* is technically separate — it ages naturally rather than through wet-piling. See [puerh.app](https://puerh.app) for the full taxonomy.
Will 5g really show me what this tea is?
Yes, for two to three sessions of short gongfu steeps. It's a taste, not a daily supply. If you love a sample, the full cakes live at [shop.puerh.app](https://shop.puerh.app).
How old is the *Liù Bǎo* in this box?
Pressed in 2018, basket-aged in Wuzhou ever since. Six years is young by *Liù Bǎo* standards but enough to show clean betel-nut and aged-wood character.
Does dark tea contain caffeine?
Yes, roughly comparable to black tea, though the long post-fermentation softens its edge. Most drinkers find it less stimulating in feel, even if the lab numbers are similar.
Why does my *shú pǔ'ěr* taste a bit fishy at first?
Residual pile aroma from young *shú*. The rinse step removes most of it; a year or two of additional rest erases the rest. Our 2019 lot is already past that stage.
Can I cold-brew these samples?
You can, but it's not their best form. Dark tea is built for heat. If you want cold-brew samples, look at our summer green and white box on [tea.gratis](https://tea.gratis).
How long can I keep an unopened sleeve?
Indefinitely, if stored cool, dry and away from strong smells. Dark tea gets better with rest — a sleeve forgotten for two years will likely taste rounder than today.
Do you ship internationally?
Yes, with shipping cost shown upfront before checkout. See the shipping page for regions and rates. One sample box per household per quarter.
