Acaia Pearl Coffee Scale (Classic White)

The Acaia Pearl is the benchmark coffee scale for brewers who care about consistency - rebuilt from the ground up with Acaia's latest weighing technology, a real-time flow-rate indicator, and USB-C charging. Whether you're pulling a careful V60, dialling in a Chemex, or dosing grounds into your portafilter, the Pearl gives you the accuracy and control to make every brew repeatable.

Faster, Smarter, and Built for Serious Brewing

The Pearl stabilises faster and more accurately than its predecessor, so you spend less time waiting and more time focused on your brew. Its 160 × 160 mm platform comfortably accommodates a wide range of brewers - from a Hario V60 to a Chemex - without getting in the way.

Real-Time Flow-Rate Indicator

A visual tool that shows your pouring speed as it happens, helping you hit consistent extraction ratios and build better pouring technique over time. Particularly useful when learning new recipes or training others.

Essential Brewing Modes

Dual Display Mode, Auto-Start Timer Mode, and Beverage Mode cover every brewing scenario - from a focused single-cup pour-over to a quick batch brew. The Pearl adapts to your workflow, not the other way around.

Optimised for Any Light

The bright 8-digit LED display is fully adjustable, readable indoors under café lighting and outside in direct sunlight. No squinting, no guesswork.

USB-C Charging & Long Battery Life

30–40 hours of battery life with USB-C PD charging. Brew one cup a day and you'll charge it every few months. The cable is included in the box.

Who Is the Acaia Pearl For?

The Pearl is the go-to scale for coffee enthusiasts who want precision across their whole brew setup. It's most at home in filter and pour-over brewing - V60, Chemex, AeroPress, Kalita Wave, batch brew - but it's equally useful for espresso dosing, weighing grounds directly into your portafilter before pulling a shot. If you want one versatile scale that covers every method, the Pearl is it. Pair it with our brew guides to get the most out of it from day one.

Not sure whether the Pearl or the Acaia Lunar is right for you? The Pearl's 160 mm platform and brewing modes make it the better choice for filter-first setups, and it works well for espresso dosing too. The Lunar is purpose-built to sit on an espresso machine drip tray for live shot weighing, with a finer 0.01g readability. If espresso is your primary method, the Lunar is worth considering.

Frequently asked questions

What can I use the Acaia Pearl for?

The Pearl is most commonly used for filter and pour-over brewing — V60, Chemex, AeroPress, Kalita Wave, and batch brew. It's also widely used for espresso dosing, weighing your ground coffee directly into the portafilter before pulling a shot. If you want one scale that works across your whole coffee setup, the Pearl handles it all.

What is the difference between the Acaia Pearl and the Acaia Lunar?

The Pearl (160 × 160 mm, 0.1g readability) is a versatile all-rounder — best suited to filter and pour-over brewing, and excellent for espresso dosing. The Lunar (105 × 105 mm, 0.01g readability) is purpose-built to sit on an espresso machine drip tray for live shot weighing, with finer precision and a flow-rate indicator tuned for espresso extraction. If filter coffee is your main method, choose the Pearl. If you're primarily pulling espresso and want the scale under the cup, choose the Lunar.

Does the Acaia Pearl work with the Acaia app?

Yes. Download the free Acaia app (iOS and Android), then hold the timer button to activate Bluetooth pairing mode. The app gives you access to additional brewing modes, brew logging, and firmware updates to keep the scale running its best.

How do I charge the Acaia Pearl?

The Pearl charges via USB-C — the cable is included in the box. Battery life is 30–40 hours, so for home use most people charge it every few months if brewing one cup a day.

Is the Acaia Pearl worth the price?

For anyone serious about their brewing, yes. The real-time flow-rate indicator transforms how you understand your pour, the build quality is designed to last years, and the versatility across brew methods means it earns its place in any coffee setup. If you're committed to improving your brewing, the Pearl delivers.

What brewers fit on the Acaia Pearl?

The 160 × 160 mm platform comfortably fits a Hario V60 (01 and 02), Chemex (all sizes), AeroPress, Kalita Wave, and most other pour-over and filter brewers. It also works well under a server or carafe for batch brewing, and on a flat surface for espresso dosing.
