How to check tea before buying

There is no single home test for authentic tea. Fraud means that the ingredients, origin, age or producer differ from what was claimed. Clearly labelled flavoured tea is not counterfeit, and a tea you dislike is not necessarily fake.

Check the specific claim

Save the listing and ask what supports the details that matter to you: region, year, cultivar or absence of additives. For factory pu-erh, request packaging photographs and batch information. If the producer offers authentication, use its official website or support team. Security features change between years and products; a random online photograph is not a reference for every release.

Do not count infusions to detect flavouring

Tea can have intense floral or fruity aromas without additives. Their persistence depends on the tea, storage and brewing; a sharp decline after two or three infusions does not prove flavouring. Jasmine tea is traditionally scented with fresh flowers. “Milk oolong” may describe naturally creamy notes or an added flavour, so check the ingredients. The problem is concealing additives, not simply using them.

Do not date pu-erh by colour

Dark leaves, old paper, a smooth taste or ten infusions do not establish age. Storage in a more humid climate is not automatically fraud; what matters is whether the stated history is accurate and the tea is in sound condition. Ask about the batch’s source and storage. Do not taste tea with suspicious growth, dampness or a clear mould smell. Rinsing does not make such tea safe.

What brewed leaves can tell you

Brewed leaves show size, buds, stems, breakage and variation within the sample. They do not reliably identify a village, tree age, hand picking or a claimed cultivar. A blend is not deceptive unless sold as something else. Not every oolong has a visible red rim; Tieguanyin can be roasted, and a strong roast on Da Hong Pao does not itself indicate a fake.

If you are unsure about a purchase

Photograph the packaging, batch number and problem, and keep the receipt and correspondence. Ask the seller to explain the specific discrepancy. If needed, contact the producer or use the shop’s returns process. An unpleasant taste alone does not establish origin. If bitterness is the only issue and there are no signs of spoilage, first try less leaf or a shorter infusion.

Questions and answers

Can a laboratory prove the region?

Some methods compare samples against validated reference data, but no universal test can identify the village and tree age from any cup of tea. When buying tea, it is more useful to ask where that batch came from and how it reached the seller.

Does a high price protect against counterfeits?

No. Price, a familiar logo or a stated plantation elevation cannot replace checking the seller and product. If you are paying extra for a rare origin, ask for supporting evidence before buying.
