Features of the Acaia Pearl S
Brewguide step by step
The Pearl S shows brewing recipes directly on the display. You search for recipes and load them onto the scale with the free Acaia app, and you can upload your own recipes and share them with others. The display then guides you through the individual steps, without a phone in your hand.
Flow rate in real time
The triple display shows flow rate, time and weight side by side. With the flow rate you can refine the pace and force of your pour. How evenly the water runs through the coffee bed influences which of the more than 800 aroma compounds are extracted.
Brewing modes for every method
Acaia lists eight modes: weighing only, Dual Display with timer and weight, Pour-Over with automatic timer start, Portafilter mode with automatic tare for the portafilter, Espresso, Flowrate, Brewguide and Countdown.
Sound and voice announcements
Weight and time can be announced by sound or voice. The settings are adjustable, and if you prefer quiet, you can switch the announcements off.
Readable even in sunlight
The brightness of the dot matrix display is tuned so that it stays easy to read outdoors as well.
Countdown timer
Three presets and more than 30 melodies that signal the end of the waiting time.
The details in everyday use
For us, good coffee starts with the ratio. We describe extraction by weight, and 1:2 is a good starting point. Time is a guide, weight is the reference. No shot is like yesterday’s, because the bean, the humidity and you yourself change every day. The Pearl S delivers data, not a verdict. No espresso police, our opinion is one of many.
You only need the app for recipes. Weighing, timer, Espresso, Portafilter and Pour-Over mode work without a phone. The battery charges via USB-C and, according to Acaia, lasts 16 to 40 hours depending on brightness and settings. For cleaning, Acaia recommends a soft cloth with warm water, without detergents or chemicals.
A simple scale weighs just as reliably for the vast majority. With its display, app and Brewguide, the Pearl S says something different. Nobody needs one or the other, you want it or you don’t.

Who the Pearl S is made for
For everyone who wants to see what is happening while brewing, at the portafilter as well as at the pour-over. If you make pour-over, you use flow rate and Brewguide. If you make espresso, you use Espresso and Portafilter mode. Every coffee path is welcome.
What goes with it
For scales: for everyone who wants a scale that is affordable and precise, there are the Normcore coffee scales. If you want app, flow rate and Bluetooth, you will find them in the Acaia Collection.
For grinding: for everyone who wants a grinder that is affordable and precise, there are the Varia VS3, Comandante C40 and Timemore in our coffee grinders and hand grinders. If you want more: Varia VS6, Weber Workshops EG-1 or Option-O Lagom. For pour-over, the Hario V60 from the Hario Collection and the AeroPress are a good fit, and you will find further accessories in our filter equipment. For espresso, our espresso machines are ready.

Frequently asked questions about the Acaia Pearl S
How does the Pearl S differ from the Acaia Pearl?
Both measure 160 × 160 × 32 mm and have a resolution of 0.1 g. The Pearl S weighs up to 3000 g instead of 2000 g, has a dot matrix display instead of an 8-digit LED display, signals with sound, melody or voice instead of sound only, and additionally offers Espresso, Flowrate, Brewguide and Countdown modes as well as the Brewguide via the app.
Is the Acaia Pearl S suitable for espresso and pour-over?
Yes. For espresso there are the Espresso mode and the Portafilter mode, which tares the portafilter automatically. For pour-over, the timer starts automatically and the flow rate runs in real time. The included heat-resistant pad protects the surface.
Do I need the app to use the Acaia Pearl S?
No. Weighing, timer and the brewing modes work without a phone. You only need the free Acaia app to search for Brewguide recipes, load them onto the scale or share them.
How long does the battery of the Acaia Pearl S last?
Acaia states 16 to 40 hours of continuous operation, depending on display brightness and settings. It charges via USB-C, and the cable is included.
Can I see the product before buying?
Yes, in our showrooms in Bern (Gerberngasse 44) and Zürich (Hagenholzstrasse 50b) you can see the Pearl S live. Not every model is on site at all times, so write to [email protected] in advance.
How quickly will the Acaia Pearl S be delivered?
We deliver within 2 to 4 working days throughout Switzerland and to Liechtenstein. Click & Collect is available in Bern and Zürich. More at coffeecoachingclub.ch.
Tip from the roastery: For espresso on the Pearl S we like to use Cozy Chocolate or Nutty Delight, full-bodied and sweet. If you are looking for maximum body without acidity, reach for Very Nutty. For a fruity pour-over with Brewguide, Wild Peach is ready. That is our recommendation, one of many.
