Scales

In espresso preparation, scales are a precision instrument that allows the barista to follow the coffee recipe with milligram accuracy. In the specialty coffee culture, a standardised in:out ratio (coffee grind weight to espresso volume) ensures a consistent flavour profile in every drink prepared. BHS offers barista scales to HoReCa businesses.

Types and functions of barista scales

Espresso scales with built-in timer — scales placed under the portafilter outlet display espresso weight in real time along with extraction time. They allow precise control of both coffee grind weight (in) and espresso weight (out) — full recipe control. Coffee grind scales without timer — more compact and affordable, mainly intended for grind dosing. Flow rate scales — premium models that show the flow speed of milk or espresso in real time. Pour-over scales — designed for filtered coffee preparation, with a higher maximum weight and flow rate measurement. Compact barista scales with 0.1 g accuracy — ideal for everyday espresso control without unnecessary features. BHS helps choose the appropriate type of scale.

Accuracy and operating range

The optimal accuracy for barista scales is 0.1 g — sufficient for espresso measurement, where a 0.5 g difference can affect extraction results. Operating range: most barista scales have a range of 0–2000 g or 0–3000 g, suitable for both grind (typically 18–22 g) and espresso (30–60 g) measurement. Response speed — espresso scales with fast response (response time <0.5 sec) allow more precise determination of extraction end than slower models. Water resistance — splash-proof or waterproof construction is important in a café environment, where water splashes are common. BHS advises on scale accuracy requirements.

Timer integration and recipe

The espresso recipe includes three variables: coffee grind weight (in weight), espresso weight (out weight) and extraction time. A built-in timer allows recording all three parameters simultaneously without an additional instrument. Ratio (extraction coefficient): a typical espresso ratio is 1:2 (18 g grind → 36 g espresso); ristretto ~1:1; lungo 1:3–1:4. Recipe adherence with scales ensures consistency between shifts and after coffee grinder setting changes. BHS helps select scales with the most suitable timer function.

HoReCa usage scenarios

In a specialty café, a barista using espresso scales and a timer determines that the optimal ratio for this coffee batch is 18 g grind → 36 g espresso in 28 seconds — this recipe is recorded and followed throughout the shift. In a café training a new barista, scales help the new barista learn to dose grind and control extraction according to the recipe, without relying solely on visual and taste assessment.

Frequently asked questions

Are scales necessary for a professional café? In specialty coffee and high-quality cafés — yes, scales are the standard for recipe control. In high-volume cafés with fixed grinder settings — scales help calibrate settings and check consistency. BHS advises on scale integration in café operations.

How to clean barista scales? Clean the surface with a damp cloth. Do not expose to a stream of water or wash under running water unless waterproof. Store scales in a dry place when not in use. Calibrate with a certified calibration weight at the frequency specified for the model. BHS advises on scale calibration and maintenance.
