Mahlkönig Coffee Grinders: Which grinder is right for your café, roastery, or setup?
If you’re serious about espresso—whether as a home barista, café owner, or roaster—sooner or later you’ll come across one name: Mahlkönig.
But why do so many professionals rely on these grinders? And more importantly: Which Mahlkönig is the right one for your setup?
In this article, you won’t get a superficial product overview, but a practical assessment based on real-world experience—including technical insights, B2B expertise, and clear recommendations.
Why the coffee grinder is more important than the espresso machine
“A good grinder paired with a simple machine delivers better results than a poor grinder paired with an expensive machine.”
– Steffen Fromm
This sentence sums it up perfectly.
Many people invest first in an expensive portafilter machine—and then skimp on the grinder. The problem: The machine can only process what the grinder delivers.
The reality:
- The machine generates pressure and temperature
- The grinder determines the extraction
- The particle structure determines the flavor
“An espresso machine forces water through a bed of ground coffee at a defined pressure.”
– Steffen Fromm
And it is precisely this bed of ground coffee that is created in the grinder—not in the machine.
Mahlkönig at a glance: Why the brand is the B2B standard
Mahlkönig has been a fixture in the professional coffee market for decades. The brand is considered a benchmark, particularly in the specialty coffee sector.
The reasons are clear:
- In-house production of grinding discs in Germany
- very consistent particle distribution, which is crucial for espresso
- Extremely high reliability in continuous operation
- a robust service and spare parts network
Especially in the B2B sector, it’s not just taste that counts, but also consistency, speed, and cost-effectiveness. This is exactly where Mahlkönig shines.

GbW vs. GbS – what really matters today
A key difference in modern Mahlkönig grinders lies in the technology:
Grind-by-Weight (GbW)
- Integrated scale
- stops automatically at target weight
- very high dosing accuracy
Grind-by-Sync (GbS)
- Communicates with the espresso machine
- automatically adjusts the grind setting
- compensates for fluctuations caused by bean age or humidity
Important: GbS is the current standard in the professional sector and is increasingly replacing the older GbW technology.
For cafés, this means one thing above all: less manual readjustment and more consistent quality throughout the day.
A comparison of the most important Mahlkönig models
E64 WS – Entry into the professional league
The E64 WS bridges the gap between home baristas and professional use.
- 64 mm grinding discs
- Grind-by-Weight and Sync
- Compact and precise
Ideal for:
- ambitious home baristas
- Small setups with low volume
E65W GbS – the new standard in cafés
The E65W GbS is currently the most important grinder in the Mahlkönig portfolio for cafés.
- 65 mm grinding discs
- Grind-by-Sync technology
- Approx. 80–120 brews per day
Perfect for:
- small to medium-sized cafés
- Consistent espresso quality with minimal effort
E80W GbS – for high-volume cafés
When it comes to speed and throughput, there’s no getting around the E80.
- 80 mm grinding discs
- Very high grinding speed
- Optimized for rush hours
Recommendation:
- from approx. 120–250 brews per day
- Multiple baristas on duty
Important point: Many cafés underestimate their growth. A café that currently serves 80 cups a day often quickly reaches 150—and then the grinder becomes the bottleneck.
EK43 – the legend
The EK43 is probably the most famous coffee grinder in the world.
- 98 mm grinding discs
- Extremely narrow particle distribution
- Ideal for filter and specialty coffee
It has been used for years in international barista championships and has significantly shaped the specialty coffee market.
Important: For pure espresso use in a café, there are better alternatives available today, such as the E65 or E80.
VTA 6S – the shop grinder for roasteries and wholesale
The VTA 6S is in a league of its own.
- 120 mm grinding discs
- Up to 43 g/s grinding capacity
- Three-phase operation
Typical applications:
- Roasteries
- Retail
- Wholesale
This isn’t about espresso shots, but about kilograms per day.

Why large grinding discs make a real difference
One factor that is often underestimated is the size of the burrs.
The rule of thumb: The larger the burrs, the more consistent the extraction.
- fewer fine particles (fines)
- fewer coarse particles (boulders)
- More consistent brew times
This results in:
- clearer flavors
- less bitterness
- greater consistency in daily operations
This is especially crucial in the B2B sector—because guests notice fluctuations immediately.
Mahlkönig, Fiorenzato, Mazzer, or Eureka—how do the brands differ?
Not every café automatically needs a Mahlkönig. And not every cheaper grinder is automatically the worse choice. The key question is always which workflow, volume, and flavor profile suit your business.
The following table helps with an initial assessment:
| Brand | Typical Focus | Strengths | Typical Weaknesses | Suitable for |
|---|---|---|---|---|
| Mahlkönig | Specialty Coffee, B2B, High-End Food Service | Very fine particle distribution, high consistency, good system integration, robust GbS/GbW solutions | High price, not every model is economically viable for every café | Specialty cafés, professional setups, roasteries, high-growth businesses |
| Fiorenzato | Espresso catering, value for money, classic bar workflows | Strong espresso performance, solid technology, often attractive price, robust construction | less system depth than Mahlkönig, somewhat less of a benchmark in the specialty segment | Cafés focused on espresso, price-conscious businesses, classic hospitality |
| Mazzer | Classic espresso grinders, durability, traditional bar concepts | Extremely robust, durable, proven, strong reputation in the classic espresso world | Depending on the model, less modern workflow, less focus on digital integration | Espresso bars, traditional cafés, establishments focused on durability |
| Eureka | Home baristas, small food service establishments, good value for money | Quiet models, excellent value for money, broad portfolio, very attractive for many setups | Depending on the model, less B2B depth; not always the first choice for high-volume operations | Home baristas, small cafés, beginners, and mid-range budgets |
Important: There is no single “best” brand. Those seeking maximum consistency, technical depth, and system integration often end up with Mahlkönig. Those looking for a classic espresso setup with a strong price-performance ratio can do very well with Fiorenzato, Mazzer, or Eureka, depending on the application.
Common mistakes when choosing a grinder—and why they can be costly
1. Budget too small for the grinder
A €1,500 machine paired with a €400 grinder is a classic combination—and almost always a mistake.
2. Timer instead of weight
Dosing by time leads to inconsistencies, especially with different beans or fluctuating humidity.
3. No scalability
Many cafés grow faster than expected—and the grinder can’t keep up.
4. Single dosing in the café
Great for home use, but inefficient and too slow in a café.
