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

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)

1. Before moving in:
   Tare = 250 g → Zeroing → Ground coffee:
   The actual amount is between 17.95 g and 18.05 g.

2. 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)

1. Before purchase: 17.5 g to 18.5 g

2. After retrieval: 35.5 g to 36.5 g

🔸 Total deviation: ±1.0 g
🔸 Error rate: 2.8%

Impact on the result

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 .

Technological and artisanal advantages of Acaia scales

• Manual calibration of each device: Every Acaia scale is individually tested and fine-tuned to ensure absolute accuracy.

• High response speed: Instant weight display for real-time measurement during extraction.

• Bluetooth & App Connectivity: For data logging, timer and recipe management.

• Robust design: The Lunar with its solid aluminum housing is ideal for use under the portafilter machine.

• Minimalist aesthetics: Reduced design that combines functionality and style.

Conclusion: Precision means control – and manual work

With an Acaia espresso scale, you don't get a mass-produced item, but a precision-engineered measuring instrument – ​​calibrated by hand and tested for absolute reliability.

Whether Acaia Lunar for espresso or Acaia Pearl for filter coffee – both models offer the same philosophy: Perfect precision for perfect taste.
