Tea equipment is an easy place to spend a lot of money for very little improvement in the cup. Here is where the money actually does something, based on what has survived on our shelf over seven years and what quietly moved to the back of a cupboard.
Four things worth buying
1. A basket infuser that fits your mug. Not a ball, not a squeeze clamp, not a novelty animal. Tea leaves need room to unfurl and circulate; a cramped ball infuser produces a weak, uneven brew from good leaf. A wide stainless basket costs about ten dollars and is the single biggest improvement most people can make. Buy the widest one that fits.
2. A digital scale reading to 0.1 g. Around fifteen dollars. Tea leaves vary enormously in density — a teaspoon of fluffy white tea and a teaspoon of tightly rolled oolong differ by a factor of three in weight. Volume measurement is the reason your cups are inconsistent.
3. A gaiwan, 100–120 ml. If you want to explore oolong and puerh properly, this is the tool. Porcelain, lidded, cheap, dishwasher-safe, holds no flavour between teas. Around twenty dollars, and more useful than a clay pot for anyone still deciding what they like.
4. Double-lid storage tins. Covered in detail in the storage guide. Around five dollars each and they extend the useful life of every tea you own.
Three you can skip
The $200 variable-temperature kettle. Genuinely convenient, and if you make tea several times a day it is a pleasant thing to own. But a basic kettle plus a $12 probe thermometer plus two minutes of patience produces identical water. This is a comfort purchase, not a quality one, and it should be the last thing you buy rather than the first.
Yixing clay pots, at the start. Beautiful, and they do develop character with use. But unglazed clay absorbs flavour, so a pot should be dedicated to one type of tea — which means you need to know what you drink most before buying. Buy one in year three, not week one.
Novelty glass blooming-tea sets. Lovely to look at. The tea inside is almost always mediocre, because the product is the display.
The cheapest useful upgrade
A $12 instant-read probe thermometer. That is it. It converts every guess in your tea-making into a known quantity, works for cooking too, and is the reason our brewing charts are reproducible. If you buy exactly one thing after reading this site, buy that.
Runner-up: a plain white porcelain cup. Coloured and patterned interiors make it impossible to read liquor colour, which is genuinely informative — a dull, cloudy brew usually means water that is too hard or leaf that is too old.
Caring for what you own
- Rinse infusers immediately. Dried tannin stains and eventually taints.
- Never use soap on unglazed clay. Hot water only.
- Descale a kettle monthly with a 1:3 white vinegar and water solution, then boil twice with fresh water. Scale changes the mineral content of your brew.
- Keep one cup as your reference cup and taste new teas in it. Comparing across different vessels introduces a variable you do not need.
None of this is expensive, and none of it is precious. Good tea should be a daily habit rather than a ceremony you have to prepare for — the equipment above is chosen to make the daily version reliably good.
