Why Sandry chose this kettle

Sandry Law spent two years cycling through kettles in the Kunming office before settling on this model. The brief was narrow — a kettle that could hold 85°C steady through a long gàiwǎn session without drifting, pour clean enough for a thin-rim cup, and stay quiet during recorded tastings. Most consumer kettles failed on at least one of those tests.

The winning unit comes from a small OEM workshop outside Foshan that supplies hotel suppliers across Guangdong. Sandry routed the order through Teamotea’s hardware channel rather than retail, which let her specify the double-wall lid (to keep the handle cool) and the silent auto-off (the stock version had a loud click that ruined session recordings). The temperature plate is calibrated against a lab thermometer on intake — units that drift more than 1°C from preset are returned.

The kettle now sits on every Teamotea bench from Kunming to the Hunan tasting room, and travels in the buyer’s case during procurement trips. It is the same kettle Zhou Xiang uses to evaluate Hunan greens, and the one Amgalan Chin packs for pǔ’ěr (普洱) aging audits in Kunming warehouses.

It is not a beautiful object. It is a working tool, and Sandry’s preference for working tools over decorative ones runs through most of what she puts on the shelves at shop.thetea.app and shop.puerh.app.

The leaf, brewed

How the kettle behaves on the bench

dry leaf

Cool matte stainless, soft brushed grain — no visible welds, lid sits flush without rattle.

wet leaf

After a 100°C boil the body stays touchable at the handle; spout cools within thirty seconds.

liquor

Pour arc is narrow and steady — water lands without splash, ideal for *gàiwǎn* (盖碗) rims.

aroma

No metallic note in fresh-drawn water, even on first boil of the day. Steam reads neutral.

taste

Holds 85°C within ±1°C across a full 1L draw — green teas stay sweet, no scorched edge in the cup.

finish

Auto-off is silent. No beep, no click — the room stays quiet enough for service.

Brewing

A method, not a recipe.
