ACAIA
Faster, More Reliable Weighing
Newer weighing hardware means the Pearl settles on a reading quicker and holds it more consistently than earlier scales, so the display keeps pace with a fast pour instead of lagging behind it. The body is built to industrial standards and recharges over USB-C, so it's designed to stay on the counter for years.
ACAIA
A Mode for However You Brew
Switch between dual display, auto-tare, beverage, pour-over and portafilter modes depending on what's in front of you — one scale that adapts to a V60 in the morning and an espresso shot at the machine later on, rather than a single fixed way of working.
ACAIA
A Display You Can Actually Read
Adjustable brightness keeps the screen legible whether you're brewing by a sunny window or in a dim kitchen, and the real-time flow-rate indicator shows your pour speed as you go — so you can see, not guess, whether you're pouring too fast or too slow for the recipe.
ACAIA
Pairs With the Acaia App
Connect over Bluetooth to the Acaia app to save brew recipes, review your pours and share them with other Acaia owners. The scale works just as well on its own — the app is there for when you want to dig deeper into your technique.

Frequently asked questions
Is the Acaia Pearl good for espresso as well as pour-over?
The Pearl is built as an all-purpose brewing scale, so it handles pour-over, AeroPress and moka pot brewing very well, and it will weigh espresso shots too. If espresso is your main use and you want something that sits neatly on a machine's drip tray, Acaia's compact Lunar scale is the more purpose-built option.
Does the Acaia Pearl connect to an app?
Yes — the Pearl pairs over Bluetooth 5.0 with the free Acaia app for iOS and Android, which logs your brew recipes, tracks weight and flow over time, and lets you replay a recipe step by step. The scale also works perfectly well on its own, without the app.
How do I look after the Acaia Pearl, and what does the warranty cover?
Wipe it with a soft, slightly damp cloth — never submerge it or use detergents, which can damage the anodised coating. It's covered by a 2-year manufacturer's warranty. Recharge via USB-C; a full charge lasts 30–40 hours of typical brewing.
Does the Acaia Pearl need a UK plug or adapter?
No — the Pearl charges over USB-C from any standard USB power source, so it works straight out of the box in the UK with no adapter needed. It ships with a USB-C cable; you'll just need your own USB plug or power bank.
Acaia Pearl or Acaia Lunar — which should I choose?
Choose the Pearl for pour-over, AeroPress and general filter brewing, where its dual display and flow-rate indicator help you dial in a recipe. Choose the Lunar if you're mainly weighing espresso shots on a machine's drip tray — it's smaller, sits neatly under a portafilter, and is built specifically for that job.

The Pearl is Acaia's all-purpose brewing scale — equally at home under a V60, an AeroPress or a moka pot. If you're weighing shots at the machine rather than filter coffee at the counter, the compact Acaia Lunar is built for that job instead.
