Two espresso scales from Prima Coffee: the Wacaco Exagram at $34.90 and the Acaia Lunar (2021) at $250.00.

We earn from qualifying purchases, including as an Amazon Associate, from Prima Coffee, and from Flair Espresso. No brand-paid placements.

If you weigh your dose and your shot, you will dial in faster than you will by volume alone. These two cover that job: a compact everyday scale and a premium Acaia.

We kept this page to espresso scales, not kitchen scales.

Why we picked it

The 2021 Acaia Lunar is the premium espresso scale Prima Coffee had in stock. Prima describes it as water-resistant, with refinements aimed at people who want more precision than a basic timer scale.

What we like

Water-resistant design, per Prima Coffee
Built as an espresso scale, not a general kitchen scale
The upgrade if you already know you want an Acaia

How to choose

Buy the Exagram if you want a small, inexpensive scale with 0.1 g resolution and a timer. Buy the 2021 Acaia Lunar if you already know you want that platform and you are comfortable spending $250.00.

Place the cup on the scale, tare, and brew. A timer on the scale saves you from watching a separate clock.
