Mahlkönig Sync, Fiorenzato ADAPT, Dalla Corte Grinder Control System: Grinders and espresso machines now communicate with each other, and at the same time catering technology is moving into the cloud. This guide sorts out which system actually controls what, where the limits are and from what throughput the technology pays off. It also covers the technology that underlies all systems and is nevertheless rarely treated as such: the scale. With a complete example calculation for a business with three tonnes annual consumption.
Data as of: 23 September 2026. All price and market values are shown with dates. Information without reliable public sources is marked as such. The information on Fiorenzato ADAPT is based on the linked manufacturer page; for the other systems the text relies on public manufacturer information as of the stated date.
The gram nobody sees
A business with three tonnes of espresso beans per year works from a recipe with 18 grams in the double basket. The grinder runs on a timer, the bean dries out over the course of the day, and nobody weighs every shot. On average one gram too much ends up in the portafilter.
This one gram costs the business, in purely mathematical terms, about 158 kilograms of coffee per year. That is 5.26 percent of the total bean volume, disappeared in a deviation that does not show up on any invoice and does not appear in any inventory. The full calculation including dial-in waste is further down in this article.
It is precisely at this point that two technologies come into play, which have been pushing into the market for about three years and are often lumped together even though they solve different problems: automatic grind size control between grinder and machine, usually marketed under names like Sync or ADAPT, and the IoT connection of the machine to a cloud platform.
Why the grind size drifts at all
A grind size set once does not remain stable. Several effects ensure this, which interact in daily business:
- Degassing: Freshly roasted beans release CO2 over days. That noticeably changes extraction behavior.
- Relative humidity and ambient temperature: Both influence the grinding result and thus the flow rate. No manufacturer publicly states that these two values are measured in the control electronics of their grinders; the systems measure the effect at the shot, not the cause in the air.
- Burr temperature: A grinder under peak load grinds differently than a cold grinder in the morning.
- Batch and variety changes: Each new lot needs its own starting point.
- Staff turnover: In an operation with high turnover the daily shift decides whether anyone adjusts at all and how consistently.
The classic answer to this is dial-in: the barista pulls test shots, corrects, pulls again. Each of these test shots costs coffee and labor time. Independent measurement series for the actual waste caused by dial-in in German businesses are not publicly available, which is why the sample calculation further below discloses its assumptions.
What Sync means technically
All systems on the market follow the same basic idea: the machine measures what actually happens in the cup and sends this information back to the grinder. Three things differ, and exactly these three differences determine the suitability for your operation.
Controlled variable: time, weight or flow
Mahlkönig controls via shot time: the machine reports the actual shot time, the grinder compares the moving average with the recipe target. Fiorenzato reads the impulses from the machine's flow meter, i.e. the flow rate. La Marzocco uses Auto Brew Ratio with integrated scales under the group heads and thus controls the beverage weight or the ratio of grounds to output volume. Markibar and several grind-by-weight grinders operate primarily via the grounds weight.
Practically this means: a time-based system only detects a deviation after the finished shot. A weight-based system, by contrast, controls the input quantity. The combination of both has the highest explanatory power, because only dose and output together yield the brew ratio.
Closed loop or assistance system
This is the most important distinction in the whole field, and it is rarely made clear in advertising.
A closed loop adjusts the grind size itself. The motor drives the burrs, without anyone intervening. Mahlkönig Sync, Dalla Corte GCS and the TIO system from Eureka and Quick Mill operate according to this principle.
An assistance system also calculates but does not change anything. It shows the operator which direction to correct. Fiorenzato ADAPT belongs in this category: after three shots that do not match the stored recipe, a prompt appears with an adjustment recommendation, the correction itself is made manually via the adjustment ring. Markibar Izaga W Connect is, based on current sources, also to be classified here; an independent motorized adjustment is not publicly documented.
For a multi-branch operation with changing staff, the closed loop is the stronger lever because it does not depend on someone reading and implementing the prompt correctly. For an owner-operated business with an experienced team the assistance system can be the better choice: it costs less, stays manufacturer-open and leaves the decision to the human.
Data path: cable, Bluetooth or cloud
There is no single solution here either, and the choice has tangible consequences for operations.
Fiorenzato ADAPT works wired and offline. It needs no Wi‑Fi, no app and no account. The Mahlkönig Sync System with GbS grinders uses a cloud-to-cloud connection over Wi‑Fi in combination with La Marzocco, whereas in combination with Sanremo it uses a cable connection. For the Sanremo connection there is a dedicated cable. Eureka and Quick Mill couple their TIO system via Bluetooth.
The wired variant is insensitive to Wi‑Fi problems in the business and operates without transmission delay. The cloud variant, however, brings functions that a cable cannot provide: centralized recipe management across multiple sites, remote access and analysis of grinding quantities.
The systems at a glance
Mahlkönig Sync System
The currently most widely documented cross-manufacturer system. The grind-by-sync grinders E65W GbS, E80W GbS (weight-based) as well as E65T GbS and E80T GbS (time-based) receive the shot time from the machine and correct the burr gap motorically. Mahlkönig specifies the adjustment resolution as 0.001 millimetre, two sensors on the cone shaft and motor record the position. The gap can be set and read manually in micrometres.
The system is approved with La Marzocco (Linea Classic S, Linea PB and PB X, GB5 S and X, KB90, Strada S) and since the partnership with Sanremo for Café Racer, F18 and D8. For all other machines Mahlkönig positions the Sync Scale as a bridge: the scale measures the shot time independently of the machine and feeds it into the system.
Not publicly documented are the exact control equation, the number of shots considered in the moving average, the outlier logic and the step size in automatic operation. Anyone procuring the system should ask the dealer about these points.
Fiorenzato ADAPT
The counter-design: wired, capable of offline operation, manufacturer-open. ADAPT reads the flow meter signals of the espresso machine. Fiorenzato states that the connection works with all common market flow meters and operates offline, meaning the system is not fundamentally tied to a specific machine brand.
The recipe is stored via a guided self-learning procedure. If three shots deviate from the recipe, the display shows an adjustment recommendation. The new RSG adjustment ring, according to the manufacturer, works with an improved ring lock and acoustic feedback; an encoder permanently shows the burr gap on the display.
ADAPT is available on four grinders: F64 EVO ADAPT, F64 EVO PRO ADAPT, F83 E ADAPT and F83 E PRO ADAPT. Not to be confused with the new RSG adjustment ring that Fiorenzato supplies for the entire series except the F4 models: the ring is fitted on many grinders, the machine connection only on these four. Fiorenzato does not name a retrofit kit for existing grinders; ADAPT is available from the factory on these four models only.
Dalla Corte Grinder Control System
The veteran in the field. Dalla Corte introduced the Grinder Control System as early as 2005, long before the term Sync became common in the industry. The machine reports deviations from the target extraction to the grinder, which automatically adjusts grind size and dose.
Supported machines are ZERO PLUS, XT, ICON and EVO2 in combination with the grinders DC ONE and DC TWO. The system is therefore fully closed: it works exclusively within the Dalla Corte ecosystem. If you already choose this brand, you get a comprehensive ecosystem consisting of Grinder Control System, Milk Control System and the Online Control System for remote monitoring.
La Marzocco: ABR, Swift and Sistema
La Marzocco takes its own path and primarily controls on the machine side. Auto Brew Ratio works with scales under each group head and offers two operating modes: in Mass Mode the machine stops at a programmed beverage weight, in Ratio Mode it weighs the filled portafilter and stops at the stored ratio. This eliminates the need to weigh every dose to the gram. ABR is available for Linea PB, KB90, GB5S AV and Strada AV.
On the grinder side La Marzocco offers self-dosing grinders with Swift and Swift Mini. The manufacturer brings the actual grind-size control loop in-house through the partnership with Mahlkönig.
On the data side La Marzocco launched the Sistema platform in February 2026, initially in Australia and New Zealand, with a planned global rollout. Sistema consolidates beverage volumes, machine usage, performance data and service needs and is expressly designed for fleets across multiple sites. It is offered in three subscription tiers (Standard, Professional, Enterprise); prices for the German market are not publicly stated.
Other systems
Markibar Izaga W Connect: The grinder doses gravimetrically with an advertised accuracy of ±0.1 grams, works with 64‑millimetre flat burrs, 525 watts and about 4 grams per second. Markibar Connect transmits, among other things, dosing accuracy, grinding temperature, burr wear and shot counter to a cloud platform. The machine connection shows the barista the necessary correction direction.
Eureka and Quick Mill TIO: Introduced at HOST 2025, intended for the ambitious home range. Machine and grinder exchange their values via Bluetooth; if three shots fall outside the time window, the grinder corrects automatically. An independent long‑term test is not yet available.
Mahlkönig Xenia with E64 WS Home: The home counterpart from Mahlkönig, also designed as a closed loop.
Victoria Arduino: The Black Eagle with Gravitech measures and stops gravimetrically, the Mythos offers grind-by-weight depending on the version. A confirmed control loop in which the machine automatically corrects the grinder's grind size is not publicly documented for this brand.

The scale: the real key technology
In the discussion about Sync systems it is regularly overlooked what all these systems are built on. Shot time and flow are auxiliary quantities: they describe the process, not the result. The result is measured only at two points, and both are weights, namely the dose in the basket and the amount in the cup. Only from these two values does the brew ratio result, and only then is a recipe reproducibly described at all.
In other words: the scale is not an accessory to the Sync system, it is its prerequisite. And it is at the same time the only technology in this field that can be retrofitted independently of the manufacturer.
Four installation locations, four functions
The same measurement technology performs a completely different function depending on where it is installed. This distinction is worth making before investing.
| Installation location | Measures | Function | Examples |
|---|---|---|---|
| In the grinder | Grounds weight | Grind by weight: controls the input quantity and stops grinding at the target weight | Fiorenzato Sense series, Mahlkönig GbW models, Markibar Izaga W with ±0.1 g |
| In the machine | Beverage weight under the group head | Gravimetric stop: ends the shot at a target weight or target ratio | La Marzocco ABR, Victoria Arduino Black Eagle Gravitech |
| Under the portafilter, networked | Beverage weight and shot time | Data source for the control loop, makes machines without their own interface connectable | Mahlkönig Sync Scale |
| Under the portafilter, standalone | Beverage weight, time and flow rate | Pure measuring instrument, controls nothing, supports recipe dialing and training | Barista scales such as the Acaia Lunar |
The scale as a retrofit path
For businesses with an existing machine park this is the most interesting point of the whole article. The Mahlkönig Sync Scale measures weight and shot time independently of the machine and feeds the values into the manufacturer's cloud via Wi‑Fi in the 2.4 GHz band. This allows a grind-by-sync grinder to be operated on machines for which there is no approval and no interface.
Technically: 2,000 gram capacity, readability 0.1 gram, integrated timer, five weighing modes including two sync modes, battery life around 13 hours with Wi‑Fi and 17 hours without, charges via USB‑C, housing made of powder‑coated aluminium, 106 by 160 by 16 millimetres. The scale is splash‑protected but explicitly not waterproof and should not go in the dishwasher. It is compatible with the grinders E65W GbS, E80W GbS, E65T GbS, E80T GbS and the E64 WS.
The investment is in the low three‑figure range and thus by multiples below the price of a new machine. If you want to test whether automatic grind size control pays off in your own operation, this is the cheapest entry. Consider the downside: the scale sits in the drip tray, it needs charging times, stable Wi‑Fi and a place in the workflow. An integrated machine solution does not have these problems.
Barista scales: measure instead of control
Separate from this are the classic barista scales. An Acaia Lunar, for example, weighs up to 2,000 grams, resolves to 0.01 grams, recognises the vessel and shot start automatically, displays flow rate in real time and transmits via Bluetooth. What it explicitly does not do: control the machine or the grinder. It is a measuring instrument, not a control element.
For catering operations this is nevertheless not a disadvantage but another use case. Two tasks are carried out by such a scale better than any automatic system: dialing in a new recipe, because it makes the flow rate visible over the shot, and training, because a new staff member immediately sees on the display what their action caused. A closed loop relieves the staff of the correction, a scale teaches them the cause. In an operation that trains, both have their place.
What the scale costs in daily use
Measuring technology brings its own maintenance. Load cells must remain clean and mechanically unstrained, coffee grounds and milk residues must be removed daily, and a shock to the platform can displace calibration. For grind-by-weight grinders additional offset corrections are needed to compensate for residual dosing after the motor is switched off. Whoever introduces scales should include both in the cleaning routine: daily cleaning and a fixed calibration check, for example with a calibration weight at shift start.
IoT: the second level
Sync controls the cup. IoT controls the operation. Both are often marketed together, but they solve separate problems, and for multi-branch businesses the second level is often the more economically interesting.
What the machine reports
The feature set differs significantly by provider; the common denominator typically includes: beverage counters by group and button, shot times, boiler and brew temperatures, pressure values, water, milk and bean consumption, cleaning cycles and their compliance, filter lifetimes, error codes, software versions and operating hours.
On the Sanremo side the D8 platform is IoT-capable out of the box; older series before the D8 cannot be connected. The manufacturer includes a five‑year cloud subscription with the machine purchase and estimates the ongoing costs afterwards at the order of magnitude of one coffee per week. The platform is operated via the My‑Sanremo app and web tools, including parameter changes, recipe distribution and on/off schedules.
In the fully automatic machine segment the platforms are significantly more mature because fleets have been managed there for years: WMF CoffeeConnect, Schaerer Coffee Link, Franke Digital Services, Eversys e'Connect, La Cimbali Art.In.Coffee and Rancilio Connect. Schaerer and La Cimbali offer documented interfaces for connection to third‑party systems; WMF and Schaerer have been awarded the "Protected Privacy IoT Product" certificate for their platforms.
Maintenance: from rigid intervals to actual load
The most robust benefit lies here. A networked machine replaces calendar intervals with actual load: brew and grinding cycles, cleaning history and filter throughput determine the next service appointment. WMF describes precisely this trend‑based logic in its Service Monitor.
The second effect is the prepared deployment. If the technician knows the error code and operating history before travelling, they bring the right part. This is immediately quantifiable in money: published German service price lists are around 79 to 85 euros net per hour, travel time is sometimes charged at the full rate, plus 0.90 to 1.80 euros per kilometre. A visit with one hour of work, one hour of travel and 50 kilometres therefore costs about 200 to 260 euros net, without spare parts. Every avoided second visit is an amount in this range.
As a reference scale: Costa Express evaluates more than 90 sensor and data points per device for its vending fleet and documents lower downtime and lower service costs. A reliable percentage ROI is however not given in the publicly accessible case studies. Independent EBIT case studies from German café chains are also not publicly available.
Multi‑site operation: central recipes, measurable quality
For businesses with multiple locations the benefit shifts from the technology to the organisation. Three points are decisive:
- Recipe distribution: A new roast lot used to mean ten briefings in a ten‑site operation. Via the platform the recipe is set once and rolled out.
- Deviation detection: The platform shows which location misses cleanings, where shot times systematically deviate and where the consumption per drink is out of line. This is quality assurance without a test purchase.
- Comparability: Consumption per drink, drinks per opening hour and waste rate become comparable between locations. Only then does a deviation become a metric rather than a gut feeling.
Chain gastronomy
In chain gastronomy standardisation is not a side effect but the business model. Here the last nuance in flavour counts less than reproducibility across hundreds of locations and a workforce with high turnover. Exactly for this reason automatic machine manufacturers are further ahead in networking than the portafilter market: their customers have been demanding fleet management, consumption reconciliation and remote parameterisation for years.
For roasteries with catering customers this yields a concrete approach. Whoever thinks bean, recipe and machine data together can not only supply coffee to a chain customer but also prove recipe adherence across their locations. That is an argument that carries in price discussions.
Calculation example: three tonnes annual consumption
Initial situation: 3,000 kilograms of espresso beans per year, target recipe 18 grams in the double basket, actually processed on average 19 grams. 350 opening days.
Block 1: the systematic overdosing
| Size | Value |
|---|---|
| Shots at 19 g | 157,895 |
| Target consumption at 18 g | 2,842 kg |
| Excess consumption | 158 kg per year |
| Share of annual volume | 5.26 percent |
| Cost of goods at 22 Euro per kg | around 3,500 Euro |
| Cost of goods at 29 Euro per kg | around 4,600 Euro |
The price range corresponds to documented prices for organic espresso in larger packaging and order quantities. Publicly visible German prices for organic espresso beans overall range roughly between 20 and 40 euros per kilogram; binding catering purchase prices are hardly publicly available and are negotiated individually with the roastery.
Block 2: the dial-in waste
Assumption, clearly marked as such because independent measurement series are missing: three calibrations per day, 2.5 test shots each, 19 grams per shot, 350 opening days. Result: around 50 kilograms per year and per grinder, i.e. about 1,100 to 1,450 euros cost of goods. Exactly this quantity is addressed directly by Sync systems, because the correction is continuous and performed without a test shot.
What of this reaches EBIT
Together both blocks add up to about 208 kilograms or just under 7 percent of annual consumption, in cost of goods about 4,600 to 6,000 euros per year. This amount is the honest part of the calculation: it is a real cost saving and immediately affects the result.
Often additional lost revenue is also calculated: 208 kilograms would, at 18 grams, mathematically correspond to about 11,500 additional espressos. While that number is correctly calculated, it is not suitable as an EBIT effect because it assumes demand exists and because milk, staff, energy, taxes and other variable costs must be counted against it. If you argue internally with this lever, you should use the cost of goods as the reliable figure and explicitly mark the revenue calculation as an upper bound.
There are two other effects that are hard to quantify but real: saved labour time for daily adjustment and fewer complaints due to fluctuating quality.
What Sync cannot do
A control loop based on time, weight and flow does not recognise why a shot is bad. Channeling, uneven distribution in the basket, tilted tamping, a worn portafilter basket or sensory defects of the bean remain outside its field of view. In the worst case the system compensates for a craft error by choosing the wrong grind size and thus conceals it.
Nor does the automation replace the initial setting. Each of these systems needs a cleanly dialled starting recipe that is set according to taste. The technology holds the point once found; it does not find it.
And it needs data points. At low throughput a system learns more slowly, weights individual outliers more strongly and economically saves too little waste and labour time. A business with a handful of shots a day is the wrong use case.
The counter calculation
- Cloud dependency: Systems that communicate via manufacturer platforms lose their sync and management functions during network or platform outages. What functionality remains after a contract ends or a platform is discontinued is rarely regulated publicly by any provider. This question should be included in writing in the procurement process.
- Closed ecosystems: Most systems only work in defined combinations of grinder and machine. The partnership between Mahlkönig and Sanremo expands the manufacturer boundary but does not create an open industry standard. Confirmed open protocols for professional grinder‑to‑machine control loops are not documented.
- Lack of price transparency: Subscription costs, activation, retrofitting and interface access are given by most providers only on request. Uniform monthly cloud prices per machine are not publicly available.
- Sensor maintenance: Integrated scales must remain clean, mechanically unstrained and calibrated. For grind-by-weight grinders offset corrections are needed to compensate for residual dosing. The technology thus creates a small maintenance overhead itself.
- Data protection: Server location, role and rights model, data export, deletion periods, data processing agreement and behaviour at contract end should be asked directly from the provider before procurement. These details are not fully publicly available for most platforms.
- Retrofitting: Fiorenzato does not name a retrofit kit for ADAPT, Sanremo excludes connection of machines before the D8 series. Networking is therefore usually a decision at the time of purchase, not afterwards.
Classification by business type
| Business type | Recommended approach | Rationale | With us for this |
|---|---|---|---|
| Café, single location, stable team | Grind by Weight, optional assistance system like ADAPT | The lever is dosing accuracy. A closed loop rarely pays off as long as the team is stable. | Fiorenzato F83 E SENSE (1.749 €) or F83 E ADAPT (2.049 €) |
| Café with high throughput and changing staff | Closed loop with grind size control | Enough shots for a clean control, and the benefit is independent of the daily staff. | Mahlkönig E65W GbS (2.350 €) or E80W GbS (2.999 €), combined with a certified machine such as the Sanremo D8 |
| Multi‑site operation from three locations | Closed loop plus IoT platform | Central recipe distribution and deviation detection across locations are the actual value contribution. | Dalla Corte DC One (3.199 €) or DC Two (5.499 €) with an XT or Artisan |
| Chain gastronomy | Fully automatic machines with a mature fleet platform and interface | Reproducibility, remote parameterisation and integration with existing systems outweigh the last nuance in taste. | We do not carry these. Fully automatic machines with fleet platforms are not part of our range. |
| Existing machine park without Sync approval | Networked scale as a data source | Cheapest entry into automatic control without replacing the machine. Requires stable Wi‑Fi and a fixed place in the workflow. | Mahlkönig Sync Scale (250 €) |
| Roastery with catering customers | Know the compatibility with your customers' machine park and resell accordingly | Recipe adherence across customer locations becomes a selling point for the bean. | No device, but consulting. Talk to us, we know the approval lists. |
| Office and self‑service | Grind by Weight or closed loop, depending on throughput | Changing operators without briefing are the classic use case for automation. | Fiorenzato F83 E SENSE or Mahlkönig E65W GbS, depending on throughput |
The grinders from the table
Conclusion
Automatic grind-size control has arrived in the professional market but remains largely tied to defined manufacturer combinations. Whoever procures today effectively chooses an ecosystem, not a single device. The central question is not whether the system is networked, but whether it controls itself or only advises, whether it works without the internet and what remains after a cloud contract expires.
If you are looking for an entry without replacing your machine park, start with the measuring technology. The scale is the basis of all these systems, it is the only manufacturer‑independent retrofit component, and it costs a fraction of a new machine. Knowing dose and output is the first step; having them corrected automatically is the second.
The lever is economically robust in the cost of goods: one systematically overdosed gram costs a business with three tonnes annual consumption around 3,500 to 4,600 euros, the daily dial-in waste another roughly 1,100 to 1,450 euros. Anything beyond that, especially revenue calculations from saved coffee, should clearly be marked as an upper bound.
Frequently asked questions
What is Grind by Sync?
Grind by Sync denotes the direct communication between espresso machine and grinder. The machine reports shot measurements, such as shot time, flow rate or beverage weight, back to the grinder. The grinder compares these values with the stored recipe and either adjusts the grind size automatically or shows the required correction.
How do Mahlkönig Sync and Fiorenzato ADAPT differ?
Mahlkönig Sync adjusts the grind size motorically itself and in the La Marzocco combination works via Wi‑Fi and cloud, with Sanremo via cable. Fiorenzato ADAPT works wired and offline, reads the machine's flow meter signals and after three deviating shots gives the operator an adjustment recommendation that is implemented by hand.
Does Grind by Sync require an internet connection?
That depends on the system. Fiorenzato ADAPT and the cable‑based Mahlkönig‑Sanremo connection work without the internet. The cloud‑to‑cloud connection between Mahlkönig and La Marzocco and all IoT platforms, by contrast, require a stable network connection.
From what throughput is a Sync system worthwhile?
There is no universally valid threshold publicly documented. The systems regulate via averages of several shots and therefore require continuous operation. The benefit is greatest in businesses with steady trade and changing staff; with only a few shots per day it hardly pays off economically.
Can I retrofit my existing grinder?
Generally not. Fiorenzato offers ADAPT only from the factory and does not name a retrofit kit for existing grinders, and Sanremo excludes machines before the D8 series from IoT connection. One exception is the Mahlkönig Sync Scale, which serves as a data source for machines without their own interface, but the grinder itself must be a grind‑by‑sync model.
Is a scale enough instead of a Sync system?
It depends on what you want to achieve. A scale in the grinder secures the dose, a scale under the portafilter makes output and flow rate visible, and a networked scale like the Mahlkönig Sync Scale provides data for a control loop. What an autonomous barista scale does not do is the correction itself: it shows the deviation but does not adjust grinder or machine. For businesses with a stable team this is often sufficient; for changing staff the control loop is the more reliable solution.
What does IoT in the coffee machine bring for maintenance?
Service is based on actual load rather than a fixed calendar interval. Brew and grinding cycles, cleaning history and filter throughput determine the next appointment. Because the technician knows the error code and operating history before travelling, the likelihood of a second visit decreases. A on‑site visit in Germany based on published service price lists costs about 200 to 260 euros net without spare parts.
Which data does a networked coffee machine collect?
Depending on the platform typically beverage counters by group and button, shot times, temperatures, pressure values, water, milk and bean consumption, cleaning cycles, filter lifetimes, error codes, software versions and operating hours. Server location and data processing should be queried from the provider before procurement, as these details are usually not fully documented publicly.
Does automatic grind-size control replace the barista?
No. The systems hold a once dialled‑in point; they do not find it. Initial setting and sensory evaluation remain the human's responsibility. Distribution and tamping errors and channeling are not recognised by a control loop based on time, weight and flow.
