If you buy one piece of teaware, buy a kettle that lets you choose the temperature. It is the only purchase that improves every single tea in your cupboard rather than one of them, and it retires the whole business of boiling water and counting to 180 while it cools.
The gooseneck question is separate and mostly about control: a narrow spout gives you a slow, precise pour, which matters for gongfu brewing and for pour-over coffee and matters not at all for dropping water on a basket infuser.

What actually matters in a tea kettle
Temperature control to the degree, or at least presets that cover 175 / 185 / 195 / 205 °F. Anything vaguer than that defeats the purpose.
A hold function, which keeps the water at temperature for an hour. This is the feature people underrate and then cannot live without, because it makes re-steeping effortless.
Stainless or glass interior rather than exposed plastic. Water sits hot in this thing for long stretches and plastic has a taste.
- Must have: variable temperature, or at minimum four presets.
- Should have: keep-warm/hold, stainless or glass interior, 1 L or larger.
- Nice to have: gooseneck spout, count-up timer, quiet boil.
- Skip: app connectivity. It is a kettle.
Gooseneck or not
A gooseneck gives you a thin, controllable stream. For gongfu brewing into a small gaiwan it is genuinely useful; you are aiming at a 100 ml vessel and you want to direct the water at the leaf. For a mug and a basket infuser, a normal spout is fine and pours faster.
Goosenecks also hold less water for their size and take longer to fill. If your main use is a large pot of black tea for several people, a conventional kettle is the better tool.
Descale every couple of months if your water is hard. Limescale changes how a kettle heats, how long it takes, and eventually how your tea tastes. Citric acid, or half a lemon and a boil.
Common questions
Do you need a variable temperature kettle for tea?
You do not need one, but it is the most useful single upgrade for a tea drinker. Without it you boil and wait — three minutes for green tea, one for oolong — which works but is tedious and imprecise.
Is a gooseneck kettle worth it for tea?
Worth it for gongfu brewing into small vessels, where pour control matters. For a mug and an infuser basket it is a preference rather than an improvement, and it pours more slowly.
What temperature kettle setting for green tea?
175 °F. If your kettle only has presets, use the lowest one above 160 °F. Boiling water will make green tea bitter.
