Buy a small packet before a large tin
A small packet gives you room to learn what you like before a generous tin becomes a cupboard obligation.
Give a tea more than one chance
A first cup can be misleading. You may have used an unfamiliar mug, followed a rather strong recipe, or tasted the tea straight after a minty lunch. A useful sample contains enough leaf for several ordinary sessions, not just one dramatic tasting. Before buying, divide the packet weight by the amount you expect to use each time. A ten-gram sample and a twenty-five-gram sample offer quite different opportunities to change your mind.
Start with one familiar style and one genuine departure. If you already enjoy a plain breakfast tea, a second plain black tea offers a comparison you can understand. Add a lighter or more roasted option if curiosity is the point. Six unrelated samples may look exciting, but they can make it difficult to remember what each cup actually contributed. Keep the packets and write one plain sentence after drinking: too smoky for breakfast, pleasant without milk, or worth trying again.
Buy for the cup you actually make
A tea that tastes lovely during an unhurried weekend session may be awkward at work. Include a weekday trial using the water, vessel, and attention you normally have available. This is not an examination the tea must pass. It is a way of deciding whether you are buying an everyday drink or something for occasional use. Both can be worthwhile, but they call for different quantities.
When the sample is nearly finished, look at whether you reached for it voluntarily. Did you keep saving it for an ideal moment that never arrived? Did another person in the household enjoy it more? Those answers can be more useful than an ambitious flavour description. A large bag is economical only when the tea gets drunk while you still enjoy its character. Compare the price per gram, but include the likely leftovers in your decision.
Finally, check that the full-size packet is the same tea and harvest or batch where that information is available. A sample from an earlier lot is helpful, but it is not a promise that every later delivery will taste identical. Ask the seller if a change matters to you. Buying another small packet is a perfectly reasonable decision when the answer is uncertain.
