Grind by Weight Grinder Comparison: Fiorenzato vs. Eureka Atom W65 Casa
This comparison pits two **grind-by-weight (GBW) grinders against each other: the Fiorenzato All Ground Sense (64 mm burrs) and the Eureka Atom W65 Casa (65 mm burrs). Both grind by weight, meaning you only need to adjust the grind size – ideal for consistent extraction when changing beans.
Advantages of Grind by Weight- No need to re-time after adjusting the grind size
- Integrated scale stops automatically at the target weight (e.g., 18 g)
- Fiorenzato is slightly more precise: deviation ~ ±0.1 g vs. Eureka ±0.21 g
| Feature | Fiorenzato All Ground Sense | Eureka Atom W65 Casa |
|---|---|---|
| Speed | Very fast, but manual start button | Instant start upon inserting the portafilter – more convenient in a busy cafe |
| Precision | Higher consistency ( ±0.1 g) | Slightly larger fluctuations (±0.2 g) |
| **Dead space | ~7 g – low, ideal for lower through | ~19 g g – significantly higher, less critical with high |
| Cleaning | Very easy: easy access to the burr chamber, no tools required | More involved: needs grinder cleaner or tools, regular cleaning required** |
| Grind adjustmen | Stepless, fine-tuned – great for lighter roasts | Stepped – too coarse for espresso adjustments, so better for medium roasts |
| Noise level | 79 dB* – quieter | 84 dB – slightly louder |
| Weight & size | Both ~9–10 kg, height ~40–43 cm (without large hopper) | Significantly taller with optional large hopper |
- Eureka: Higher fine percentage (over 40%) → more body, sweet, balanced; ideal for medium roasts
- Fiorenzato: Narrower main peak, fewer fines → more clarity, better for light to medium roasts
- Both produce great espresso – the difference lies in personal taste direction.
- Eureka Atom W65 Casa Better for high throughput (e.g., gastronomy), instant start, easy operation, but coarse grind settings and large dead space.
- Fiorenzato All Ground Sense Better for lower to medium throughput, more precise dosing, easy cleaning, and finer adjustment – ideal for ambitious home baristas or small cafes.
- Decision: If you grind a lot and need straightforward instant use, choose Eureka. If you value precision, low dead space, and flexible settings, go with Fiorenzato.
