The Timemore Black Mirror Basic 3 is a brewing scale built around three use cases: pour-over, espresso, and general weighing. A physical slider on the side switches between the three modes, each with its own timer behavior.
- Pour-Over mode the scale shows live flow rate (g/s) and a running coffee-to-water ratio
- Espresso mode it auto-tares, starts the timer when flow is detected, and stops when the cup is removed
- Regular mode everything is manual.
Compared to the Basic 2, the Basic 3 reads accurately from 0.2 g instead of 0.5 g, adds the live ratio display, and is roughly 35% thinner. It also includes an electromagnetic shield in the chassis, which keeps readings stable when the scale sits on a machine’s drip tray or near magnetic catch cups, a common pain point with cheaper espresso scales.
