0.1g rechargeable shot scale that fits under a portafilter
About $40
Why espresso without a scale is mostly vibes
A “18g in, 36g out in ~28 seconds” recipe is impossible to hit consistently by eye. 0.1g resolution lets you control dose and yield independently from grind. Timer functions matter because shot time is your third variable. Buy a scale before another basket.
Good / better / café-nerd
Good: TIMEMORE Black Mirror or Maestri USB-C shot scales — slim, timed, affordable. Better: the same class with a heat-resistant pad and auto-tare habits you’ll actually use. Café-nerd: Acaia Pearl for flow-rate graphs, app workflows, and build that survives busy bars. Most homes never need Pearl; many think they do.
Workflow tips that matter more than brand
Tare the portafilter, dose by weight, level/WDT/tamp, tare the cup on the scale under the spout, brew to yield. Change one variable per shot. If your scale auto-offs mid-pour-over, disable auto-off or pick a model with longer timeout. Keep it dry — espresso scales live dangerous lives.
Our recommendation
Start with TIMEMORE or Maestri. Upgrade to Acaia when you’re logging shots daily and care about flow-rate feedback — not because a YouTuber’s station looks incomplete without one.
