Polaris Coffee Scale | Auto-Ratio Pour-Over Scale | 0.1–2000g

A pour-over coffee scale that does the extraction ratio math for you. No calculator, no guesswork—just a percentage display that tells you exactly how much water to pour and when to stop. Consistent coffee without the brain work.

Rarely's take: this is the scale for people who love precision but hate doing mental arithmetic before 7 a.m. The percentage display is the clever part—you set your coffee dose, it shows you a live percentage as you pour, and you stop when it hits 100%. No timers to fumble with mid-bloom, no scrambling for your phone to open a ratio calculator. Just a clean, intuitive interface that gets out of the way and lets you make good coffee.

The build is minimal—ABS and acrylic body, silicone non-slip feet, a slim profile that doesn't dominate your counter. Weighs up to 2000g in 0.1g increments, which covers pour-over, French press, and most batch-brew scenarios. It's simple, it's smart, and it removes the one annoying variable from manual brewing: wondering if you're pouring the right amount.
