Description
Pour-over is only as good as your water and your control. This gives you both — 0.5°C temperature accuracy, a stepless dial that tunes flow rate on the fly, and a built-in TDS meter that tells you if your water's specialty-ready before you brew. Made from food-grade SUS316. Curated by Nekofi and designed by Yearn Tour.
Stepless flow dial · not just an on/off spout
physical dial on the body that tunes flow rate continuously from a whisper-thin bloom pour to a full agitation pour. Adjust mid-pour without changing your grip.
0.5°C temperature precision
Nine preset shortcuts for the temperatures pour-over actually uses (85°C, 90°C, 92°C, 96°C…). Memory function remembers your last setting.
TDS pen built into the base
TDS (total dissolved solids) tells you if your water is under-mineralised (flat cup), over-mineralised (muddy cup), or in the specialty sweet spot of 75–175 ppm.
Made in SUS316, not SUS304
SUS316 stainless has higher corrosion resistance than the SUS304 used in most kettles — matters more when you're heating hard Indian tap water day after day.
Eagle-beak spout · 1.0mm
Narrow enough for a controlled bloom, wide enough to pour a full brew without stalling
Ergonomic handle
Multiple grip positions for one-handed precision or two-handed stability on long pours
Flat-top lid
Rest a finger on it to stabilise the pour. A small detail that pros will notice immediately.
Anti-scalding raised base
The kettle sits on a boat-shaped riser — hot metal never touches your countertop
1500W fast heating
Room-temp to 100°C in under 4 minutes. Anti-splash design keeps the first boil clean.
The Smart Base
C / °F switchable · nine preset shortcuts
Manual +/− adjustment · 0.5°C steps
Auto keep-warm — hold your target temp for as long as you're brewing
Timer + memory functions — the base remembers your last setting after power-off
TDS meter · 0–60°C range, ppm display
Ambient light strip — red = heating, green = holding, white = standby. Read the state of your kettle from across the kitchen.
Auto power-off after 1 hour of inactivity
