Grind-by-Weight Coffee Grinders

Buy Grind-by-Weight Coffee Grinders Switzerland

Grind-by-Weight (GbW) is the precision design of the modern espresso world: you specify a gram amount (e.g., 18.0 g), and the grinder grinds exactly that amount into the portafilter – regardless of bean density, roast level, grind size, or burr wear. An integrated precision scale continuously measures during grinding and automatically stops when the target weight is reached. The result: reproducible shots with minimal variation, ideal for specialty setups where espresso quality should remain at a consistent dosing level.

Coffee Coaching Club carries 16 active Grind-by-Weight models from eight brands: Eureka dominates the range (Mignon Libra 55, Mignon Libra 65 All Purpose, Mignon Stark W, Atom W 65 Casa, Atom 65W, Atom 75W), supplemented by the German Mahlkönig class (E64 WS, E65W GBS, E80W GBS), Italian Fiorenzato and Mazzer, the Etzinger manufacture from Liechtenstein, the ECM Exacto, the Ligre siji and the Spanish Markibar IZAGA W with Instant Dose.

Which Grind-by-Weight Grinder for Which Setup

Grind-by-Weight vs. Grind-by-Time: what is the difference?

The two dominant design classes for electric espresso grinders differ fundamentally:

Grind-by-Time (GbT): the grinder grinds for a precisely defined time (e.g., 6.5 seconds). You set the time so that your dose is dispensed (for us, usually 14.5 to 17 g). Problem: bean density varies (freshly roasted vs. older beans, light vs. dark), grind size changes affect grind output speed, burr wear over time. This leads to dosing variations typically of ±0.3–0.8g per shot.

Grind-by-Weight (GbW): the grinder has an integrated precision scale and grinds exactly the desired weight. You specify 18.0g, you get 18.0g. Reproducibility typically ±0.05–0.1g. For specialty workflow, where shot quality depends on correct dosing level, this is a clear advantage.

Grind-by-Sync (GBS): Mahlkönig has extended the GbW logic – in addition to dosing by weight, the grinder automatically adjusts the grind size to a target extraction time. For café workflow with constant extraction time.

Frequently Asked Questions

Is the GbW surcharge worth it compared to Grind-by-Time?

For specialty workflow with high reproducibility: yes. The extra cost of typically CHF 200–500 compared to the Grind-by-Time version of the same brand is worthwhile if you use different beans, often adjust the grind size, or value reproducible shot quality. For home use with only one type of bean and stable grind size: GbT is sufficient.

Eureka Mignon Libra 55 or Atom W 65 Casa?

Mignon Libra 55 (CHF 748.95–798.95): compact design, 55mm burr, perfect for home with limited space. Atom W 65 Casa (CHF 999.95): 65mm burr for more grinding speed and tonal aroma depth, taller design. For classic home use with 1–2 shots daily: Mignon Libra 55. For higher volume or specialty demands: Atom W 65.

Mahlkönig E64 WS or E65W GBS?

E64 WS (CHF 999.95): classic Grind-by-Weight design. E65W GBS (CHF 2'598.95): extended with Grind-by-Sync: dosing by weight plus automatic grind size adjustment to a target extraction time. For café workflow with constant extraction time, the surcharge is worthwhile. For home with standard demands: E64 WS is sufficient.

Mazzer Mini G or Fiorenzato F64 EVO Sense PRO?

Both are Italian professional class with 64mm burrs. Mazzer Mini G (CHF 1'149.95): classic Mazzer design, established professional brand. Fiorenzato F64 EVO Sense PRO (CHF 1'949.95): extended with EVO burr design and Sense Plus sensor technology. For standard specialty: Mazzer. For more sensor technology and the EVO burr design: Fiorenzato F64 EVO.

What do the WS and W designations mean?

For Mahlkönig: WS = Weight Scale, i.e., the Grind-by-Weight version. For Eureka: W = Weight, i.e., the GbW version. The classic models without letters are the Grind-by-Time versions.

How precise are GbW grinders really?

Typical precision for modern GbW grinders: ±0.05–0.1g. This is an order of magnitude more precise than Grind-by-Time (typically ±0.3–0.8g) and good enough for specialty demands.

Mahlkönig E64 WS vs. E65W GBS – what is GBS?

GBS = Grind-by-Sync. Mahlkönig combines dosing by weight with an automatic grind size adjustment: The grinder adjusts the grind size so that the shot hits a target extraction time. The shot time comes from a compatible espresso machine, a sync-capable device such as the Mahlkönig Sync Scale, or from manual input. Very useful for café or home with high demands.

Is GbW worth it compared to external precision scales like Acaia Pearl S?

Both have their justification. External scale (Acaia Pearl S, CHF 248.95): you weigh the exact dose after grinding, and can also track other workflow variables (shot weight, shot time). Integrated GbW grinder: the grinder automatically stops at the target weight, simpler workflow. For highest precision: a combination of both (roughly dose with GbW, fine-tune with Acaia Pearl S).

Can I see GbW grinders before buying?

Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes.
