Acaia Coffee Scale Review

Acaia scales are one of the most sold coffee scales in the US market. In order to review the Acaia coffee scale, we did test runs on all 4 models to figure out how they perform under different parameters. The Peral Model S is slightly better than the normal Pearl, but the Lunar is even better than both the Pearl models. You should go for Pyxis if you are looking for a small scale that you can carry anywhere. You’ll find a dedicated section for all 4 scales below.

Acaia Scale You Can Buy to Level Up Coffee Brewing

Coffee scales with above-average performance are hard to find in the market. Most other scales are continuously compared with Acaia scales because of their top-quality build, accuracy, and performance.

Now, let’s look at the product library.


Acaia Pearl Model S

  • Weight – 620 grams
  • Weighing Capacity – 3000 grams
  • Measuring Intervals – 0.1 gram
  • Battery – Lithium ion 2200 mAh
  • Water Resistant – No
  • Charging Type – USB C Charging (can be charged using a normal Type-C phone charger)

Compact size, high capacity, and sleek design but packed with high-end features are the key highlights of Acaia Pearl Model S. Additionally, you will see only two buttons on its body – a tare and a power button.

You get a scale with a super bright matrix LED display, probably the biggest on any scale of its size.

Features don’t end here. Let’s look at some more functional characteristics of the Acaia Pearl scale –

Real-Time Flow Rate

Out of the various modes, you are going to use this one the most.

This model is the newest addition to the coffee scale. When using this feature, the scale’s display shows the flow rate, weight, and time. Therefore, you get an average amount of water you add every second.

Using this, you can ensure the strength of your coffee. Thus, with this feature, your cup of joe will have the consistency you wish for.

Brew Guides

The engineers at Acaia seem to have a connection with coffee enthusiasts. I said so because this Acaia Pearl features a built-in interactive brewing guide. This means you will get the instructions on the screen, so you won’t need a trainer.

With the ability to set the timing and volume of each pour and intervals between them, you can plan out your go-to pour-over recipe. To access the Brew Guides function, simply hold down the tare button for two seconds. Once you enter this mode, your programmed steps will be carried out in a particular order.

Sound Notification

You can set sound notifications or voice notifications to hear the weight and time. It’s handy when you’re doing more than one task in the kitchen.

Dual Display Features

When in dual display mode, it shows the weight on the right and the timer on the left side.

Bluetooth Connectivity

The intelligent scale lets you feel independent by allowing you to control it via your phone. With the mobile app, you can update firmware, save coffee recipes, check the scale’s battery, and more.


Acaia Pearl


  • Weight – 500 grams
  • Weighing Capacity – 2000 grams
  • Measuring Intervals – 0.1 gram
  • Battery – Lithium ion 1100 mAh
  • Water Resistant – No
  • Charging Type – USB C Charging

This scale resembles all the features and form factors of its successor S model. From the feature list above, you might have noticed some downgrades compared to the S model.

Further, other features that you’ll miss are the brew guides, and instead of Matrix LED, there’s a conventional 8-digit LED display. But do these absent features make it a bad scale? Not at all!

You still get Acaia’s super reliable and fast response time. There are all the major modes like weighing, timer, auto tare, auto start, beverage, and espresso mode.

When most other coffee scales were launching with AAA batteries, the Pearl scale had a rechargeable battery. This model comes with a USB C charging port, and the USB cable is provided in the box. The battery backup is insane, with about 20-30 hours of non-stop usage. It was launched earlier to the S model but still has Bluetooth functionality, which you can use to connect to your mobile and monitor.

Still need more convincing? It also won the best coffee scale award at the SCAA Expo in 2014. Additionally, it costs less than the S model, which makes it an even better deal. Especially for beginners, this can be an ideal coffee scale.

Practical Accessories

Inside the box of Lunar scale, you get some exciting accessories. There’s a Heat Resistant Pad, Non-slip Protective Strip, Friction-reduction Protective Strip, and a Calibration Weight of 100 grams. Each of these accessories rests easily on the body.

Further, all other features it has are Acaia standard. You get the real-time flow rate indicator, USB Type C charging, built-in brewing modes, and every other feature that Pearl scale has. Also, this one is smaller than the Pearl models, making it much better for putting onto an espresso drip tray.

  • Measuring Intervals – 0.01 gram
  • Battery – Lithium ion 310 mAh

This scale defines its name without a doubt. If you noticed the weight point in the specifications chart, you must be thinking that it’s a mistake, but it’s not.

The Pyxis Ultralight actually weighs that much. It’s the lightest scale you can have with you. It’s best for traveling due to its portable form factor.

Despite being so lightweight and compact, the scale manages to deliver a world-class performance. However, it’s not the one with the highest specifications and is a bit expensive, but there are still some factors that make it special.

Let’s have a look at some of its notable features.

Ultra Sensitive Weighing Base

This tiny gadget can respond to a feather-light weight of 0.01 grams to up to 500 grams. The company claims this to be the highest resolution on any of its scales so far.

Other major features it has are Acaia standards like Bluetooth 5.0, water resistance, dual display, auto start, etc.

What should I look for in coffee scales?

Buying a coffee scale that helps you brew perfect espresso shots or pour over cups can be a bit difficult. But you can pin down the option using this checklist.

  • Precision – A accuracy of 0.1 gram is a must, or you can say it’s the standard.
  • Durability – Let’s face it, making coffee can be messy. Especially when making pour-over or using a French press, there’s a high chance of spilling water. Therefore, look for a strong build quality scale and don’t miss out on checking the quality of scale displays.
  • Size and Design – You would want something that takes less space in your kitchen, is sleek, and also fits in an espresso machine.
  • Timer – A built-in timer is essential for monitoring your brew time and achieving the perfect extraction
  • Extra features – Coffee enthusiasts would probably like to have features like pour-over mode, auto tare function, dual displays, and Bluetooth functionality. If you get these features, that’ll obviously add to ease of use, but not all of them are necessary.
