Overview

The Acaia Lunar™ is a sleek and compact espresso scale designed specifically for espresso machine drip trays, combining style and functionality. Built with anodized aluminum, it’s as durable as it is aesthetically pleasing. The internal electronics and LED display are water-resistant, offering protection from accidental spills or splashes that commonly occur during espresso preparation. With an ultra-fast response time and unmatched accuracy, the Lunar ensures precise measurement and consistency for dialing in your espresso shots every time.

Accessories

Accessories like the Lunar Weighing Plate, Base, and Carrying Case (sold separately) expand its versatility, while the included heat pad and 100 g calibration weight enhance its practicality. Backed by a 2-year limited warranty that even covers water damage, the Lunar is a scale you can rely on for both home and commercial espresso setups.

Precision & Real-Time Feedback

The Acaia Lunar boasts a sensitivity of up to 0.1 g and an optional resolution of 0.01 g, making it precise enough to detect even the slightest weight changes due to evaporation or temperature shifts. The addition of a real-time Flow-Rate Indicator, unique to the 2021 model, allows you to monitor extraction flow rates between 0.1 g and 3.4 g per second. This feature is indispensable for dialing in espresso, helping you achieve optimal brewing consistency shot after shot.

Durable & Water-Resistant

Crafted with a premium aluminum casing, the Lunar is built to last. Its robust design ensures it can handle the rigors of daily espresso brewing, while the water-resistant construction provides peace of mind. Even if fully submerged, the scale is protected from liquid damage, making it ideal for placement directly in an espresso machine’s drip tray.

Intuitive LED Display

The Lunar’s dual LED display is both bright and easy to read, showing real-time weight and timer information. Touch-sensitive buttons give it a sleek, modern aesthetic and make cleaning simple. Features like Tare Save allow you to store the weight of your favorite shot glass or demitasse, while the battery indicator lets you quickly check remaining power with a press-and-hold of the power button. These thoughtful features enhance usability and streamline your espresso-making routine.

Rechargeable USB-C Power Supply

The Lunar is powered by a rechargeable lithium-ion battery, offering 20–30 hours of use on a single charge. It includes a USB-C charging cable, a convenient and commonly used connector that makes recharging fast and simple. This eco-friendly design eliminates the need for disposable batteries, providing a greener alternative for your coffee setup.

Compact, Slim Profile

With a height of just 15 mm, the Acaia Lunar fits seamlessly under most espresso machine brew groups, ensuring it doesn’t interfere with cup clearance. Its compact design and low profile make it easy to integrate into your existing setup, whether you’re at home or in a professional environment. The black edition’s seamless bar screen and brighter LEDs further enhance visibility, adding a touch of sophistication to an already impressive tool.

Why the Acaia Lunar Stands Out

The Acaia Lunar™ isn’t just a scale—it’s an essential tool for precision espresso brewing. From its exceptional sensitivity and flow-rate monitoring to its durable, water-resistant construction, it’s built to elevate your coffee experience. Whether you’re perfecting your home barista skills or refining your café workflow, the Lunar ensures every shot is measured with unparalleled accuracy and reliability.
