Acaia calls this scale "the only scale you'll ever need to make delicious coffee." And indeed, the Pearl proves itself a true all-rounder: Baristas love it for measuring grind doses, as the entire portafilter fits on the scale and its ultra-fast response time allows for efficient work. Filter coffee brewers also appreciate the integrated stopwatch and the Bluetooth connection to the Acaia mobile apps for recording extraction values and pouring speed. Measurement increments: 0.1g up to a maximum of 2kg. Includes USB charging cable and protective mat.
The 2021 version features new user modes, including a "Portafilter Mode," and a real-time flow rate display. Battery life has also been improved, and response and startup times have been accelerated.
Precision in the cup – Why an Acaia espresso scale makes the difference
Why a precise espresso scale is crucial
In espresso preparation, every tenth of a gram determines the taste, consistency, and balance. A minimal deviation in weighing the coffee grounds or extraction volume can change the shot – from balanced to over-extracted or under-extracted.
That's why baristas worldwide trust Acaia espresso scales , available at the Coffee Coaching Club . Each scale is calibrated by hand to ensure the highest accuracy and absolute measurement stability – a quality standard that sets benchmarks in the industry.
Acaia scales compared: Lunar & Pearl
| Model | Measuring range | Deviation (0–500 g) | Special feature | Ideal for |
|---|---|---|---|---|
| Acaia Lunar | 0–500 g | ±0.05 g | Hand-calibrated, aluminum case | Espresso machine |
| Acaia Pearl | 0–500 g | ±0.2 g | Hand-calibrated, large display | Filter coffee, Brew Bar |
| Standard scale (other brand) | 0–500 g | ±0.5 g | Serial calibration | Everyday use |
This makes Acaia scales up to ten times more precise than conventional models – and all with individually tested craftsmanship.
Calculation example: How precision affects espresso
A classic espresso shot consists of:
-
Amount of coffee (input): 18.0 g
-
Espresso output (output): 36.0 g
-
Container weight (cup): 250 g
Example 1: Acaia Lunar (±0.05 g deviation)
-
Before moving in:
Tare = 250 g → Zeroing → Ground coffee:
The actual amount is between 17.95 g and 18.05 g. -
After moving in:
Total weight 286 g → actual espresso: 35.95 g to 36.05 g
🔹 Total deviation: ±0.1 g
🔹 Error rate: 0.28%
Example 2: Standard scale (±0.5 g deviation)
-
Before purchase: 17.5 g to 18.5 g
-
After retrieval: 35.5 g to 36.5 g
🔸 Total deviation: ±1.0 g
🔸 Error rate: 2.8%
Impact on the result
| parameter | Acaia Lunar | Standard scale |
|---|---|---|
| Amount of coffee | 17.95–18.05 g | 17.5–18.5 g |
| Espresso output | 35.95–36.05 g | 35.5–36.5 g |
| Brew Ratio | 1:2 | 1:1.9 – 1:2.1 |
| The taste | Consistent & balanced | Fluctuating & unpredictable |
Even deviations of 1 g significantly change the extraction ratio !
Try it yourself!
The hand-calibrated precision of an Acaia scale minimizes these errors and achieves reproducible results with every shot .
