Mahlkönig Sync, Fiorenzato ADAPT, Dalla Corte GCS: grinders and espresso machines now talk to each other, and at the same time hospitality technology is moving into the cloud. This guide clarifies which system actually controls what, where the limits lie and from what throughput the technology pays off. Plus the technology that underlies all systems and is still rarely treated as such: the scale. With a complete worked example for an operation with three tons annual consumption.
Status of the data: 23 September 2026. All price and market values are dated. Statements without reliable public sources are marked as such. The information on Fiorenzato ADAPT is based on the linked manufacturer page and was supplemented on 28 September 2026 after feedback from Fiorenzato; for the other systems the text relies on the public manufacturer statements as of the mentioned reference date.
The gram nobody sees
An operation with three tons of espresso beans per year works with a recipe of 18 grams in the double portafilter. The grinder runs time-controlled, 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 operation roughly 158 kilograms of coffee per year in calculation. That is 5,26 percent of the total bean volume, vanished in a deviation that does not appear on any invoice and does not show up in any inventory. The complete calculation including dial-in waste is further down in this article.
Two technologies address precisely this point, which have been pushing into the market for about three years and are often lumped together even though they solve different problems: the 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 grind size drifts at all
A once-set grind size does not remain stable. Several effects cause this, which interact in daily operations:
- Degassing: Freshly roasted beans release CO2 over days. That noticeably changes extraction behavior.
- Humidity and ambient temperature: Both affect the grinding result and therefore the flow. No manufacturer publicly states that these two variables are recorded in their grinders' control electronics; the systems measure the effect at the shot, not the cause in the air.
- Burr temperature: A grinder in burst operation grinds differently than a cold grinder in the morning.
- Batch and bean changes: Every new lot needs its own starting point.
- Staff changes: In an operation with high turnover the daily crew decides whether adjustments are made at all and how consistently.
The classic response is called dial-in: the barista pulls test shots, corrects, pulls again. Each of those test shots costs coffee and labor time. Independent measurements of the actual waste from dial-in in German operations are not publicly available, which is why the example calculation below makes its assumptions transparent.
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 that information back to the grinder. Three things differ, and exactly these three differences decide the suitability for your operation.
Controlled variable: time, weight or flow
Mahlkönig regulates via shot time: the machine reports the actual shot time and the grinder compares the moving average with the recipe target. Fiorenzato reads the impulses from the machine's flowmeter, that is the water amount in the shot, and matches it with the set grind size. La Marzocco uses Auto Brew Ratio with integrated scales under the groups and thus controls the beverage weight or the ratio of ground coffee to output volume. Markibar and several grind-by-weight grinders primarily work via the ground coffee weight.
Practically that means: a time-based system recognizes a deviation only after the shot is finished. A weight-based system, by contrast, controls the input quantity. The combination of both has the highest informational value, because only dose and output amount 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 moves the burrs without human intervention. Mahlkönig Sync, Dalla Corte Grinder Control System and the TIO system from Eureka and Quick Mill operate on 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 suggestion appears with an adjustment recommendation; the correction itself is done manually via the adjustment ring. Markibar Izaga W Connect is also classified here according to current sources; an independent motorized adjustment is not publicly documented.
For a multi-location operation with changing staff the closed loop is the stronger lever because it does not depend on someone reading and correctly acting on the suggestion. For an owner-operated business with an experienced team the assistance system can be the better choice: it costs less, remains 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 concrete consequences for the operation.
Fiorenzato ADAPT works cabled and offline. It needs no Wi-Fi, no app and no account. The Mahlkönig Sync System with the GbS grinders uses a cloud-to-cloud connection over Wi-Fi in combination with La Marzocco, while in combination with Sanremo it uses a cable connection. For the Sanremo connection there is a dedicated connection cable. Eureka and Quick Mill couple their TIO system via Bluetooth.
The cabled variant is insensitive to Wi-Fi problems in the operation and works without transmission delay. The cloud variant brings functions that a cable cannot provide: central recipe management across multiple sites, remote access and evaluation of grind volumes.
Systems at a glance
Mahlkönig Sync System
The currently most broadly 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 states the adjustment resolution as 0,001 millimeter; two sensors on the cone shaft and motor capture the position. The gap can be manually set and read in micrometers.
The system is approved for 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 shot time independently of the machine and feeds it into the system.
Not publicly documented are the exact control equation, the number of considered shots in the moving average, the outlier logic and the step size in automatic operation. If you procure the system, you should ask the dealer about these points.
Fiorenzato ADAPT
The counterproposal: cabled, offline-capable, manufacturer-open. ADAPT reads the flowmeter signals of the espresso machine and compares the water amount of the shot with the grind size. Fiorenzato states that the connection works with all common market flowmeters and operates offline, making the system in principle not 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 works according to the manufacturer with an improved ring lock and acoustic feedback; an encoder permanently displays 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 specifies for the entire range except the F4 models: the ring sits on many grinders, the machine connection only on these four. ADAPT cannot be retrofitted. According to Fiorenzato the ADAPT grinders have their own software, additional memory boards and a connector for the connection cable; that is more than a software update. Therefore ADAPT is only available ex works on these four models.
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 are the machines 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 world. If you already choose this brand you get a consistent ecosystem out 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 regulates on the machine side. Auto Brew Ratio works with scales under each group and knows 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. That eliminates the need to weigh each 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 actual grind size control loop the manufacturer brings in 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 worldwide rollout announced. Sistema consolidates beverage volumes, machine usage, performance data and service needs and is explicitly designed for fleets across multiple sites. It is offered in three subscription tiers (Standard, Professional, Enterprise); prices for the German market are not publicly listed.
Other systems
Markibar Izaga W Connect: The grinder doses gravimetrically with an advertised accuracy of ±0,1 grams, works with 64 millimeter flat burrs, 525 watts and roughly 4 grams per second. Markibar Connect transmits, among other things, dosing accuracy, grinding temperature, burr wear and shot counters to a cloud platform. The machine connection shows the barista the needed correction direction.
Eureka and Quick Mill TIO: Presented at HOST 2025, intended for the ambitious home sector. Machine and grinder exchange their values via Bluetooth; if three shots fall outside the time window the grinder corrects itself. 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 what regularly gets lost is what all these systems build on. Shot time and flow are auxiliary variables: they describe the process, not the result. The result is only measured at two points, and both are weights, namely the dose in the portafilter and the amount in the cup. Only from these two values does the brew ratio emerge, and only then is a recipe reproducibly described.
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 independent of the manufacturer.
Four installation locations, four functions
The same measurement technology fulfills a completely different function depending on where it is installed. This distinction is worth considering before investing.
| Installation location | Measures | Function | Examples |
|---|---|---|---|
| In the grinder | Ground coffee 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 | Gravimetric stop: ends the shot at 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, regulates nothing, supports dialing in and training | Barista scales like the Acaia Lunar |
The scale as a retrofit path
For operations 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 via Wi‑Fi in the 2.4‑gigahertz band into the manufacturer's cloud. That allows a grind-by-sync grinder to be used on machines for which there is no approval and no interface.
Technically: 2.000 grams capacity, readability 0,1 grams, integrated timer, five weighing modes of which two are sync modes, battery life around 13 hours with Wi‑Fi and 17 hours without, charging via USB-C, housing made of powder-coated aluminium, 106 by 160 by 16 millimeters. The scale is splash-proof but explicitly not waterproof and is not dishwasher-safe. 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-digit range and thus many times below the price of a new machine. If you want to check 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, a stable Wi‑Fi and a place in the workflow. An integrated machine solution does not have these problems.
Barista scales: measure instead of control
To be distinguished from this are the classic barista scales. An Acaia Lunar, for example, weighs up to 2.000 grams, resolves to 0,01 grams, detects vessel and shot start automatically, shows the flow rate in real time and transmits via Bluetooth. What it explicitly does not do is control the machine or the grinder. It is a measuring instrument, not a control element.
For hospitality operations that is not a disadvantage but a different use case. Two tasks are performed 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 can immediately see on the display what their action caused. A closed loop relieves 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 operation
Measurement technology brings its own maintenance effort. Load cells must remain clean and mechanically unloaded, coffee grounds and milk residues must be removed daily, and a knock to the platform can shift calibration. With grind-by-weight grinders additional offset corrections are necessary to compensate for the residual flow after the motor stops. If you introduce scales, you should include both in the cleaning routine: daily cleaning and a fixed calibration check, for example with a test weight at the start of the shift.
IoT: the second layer
Sync controls the cup. IoT controls the operation. Both are often marketed together, but they solve separate problems, and for multi-site operations the second layer is often the more economically interesting.
What the machine reports
The range of functions 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 adherence, filter lifetimes, error codes, software versions and operating hours.
For Sanremo the D8 platform is IoT-capable from the factory, older models prior to the D8 cannot be connected. The manufacturer includes a five‑year cloud subscription with the machine purchase and describes the ongoing costs thereafter as on the order 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 sector 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 received the "Protected Privacy IoT Product" certificate for their platforms.
Maintenance: from rigid intervals to actual load
The most tangible benefit lies here. A connected machine replaces the calendar interval with actual load: brew and grind cycles, cleaning history and filter throughput determine the next service appointment. WMF describes exactly 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 departure, they bring the correct part. That is immediately quantifiable in money: published German service price lists are around 79 to 85 Euro net per hour, travel time is sometimes charged at the full rate, plus 0,90 to 1,80 Euro per kilometer. A service with one hour of work, one hour of travel and 50 kilometers therefore costs about 200 to 260 Euro net, excluding 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 reduced service costs. A reliable percentage ROI is not given in the publicly available case studies. Independent EBIT case studies from German café chains are also not publicly available.
Multi-site operations: central recipes, measurable quality
For businesses with multiple locations the benefit shifts from the technology to organization. Three points are decisive:
- Recipe distribution: A new roast lot means in a ten‑site operation previously ten briefings. Via the platform the recipe is set once and rolled out.
- Deviation detection: The platform shows at which site cleanings are skipped, where shot times systematically miss and where consumption per beverage deviates. That is quality assurance without test purchases.
- Comparability: Consumption per beverage, beverages per opening hour and waste rate become comparable between locations. Only then does a deviation become a metric instead of a gut feeling.
Chain restaurants
In chain restaurants standardization is not a side effect but the business model. Here the last nuance in taste matters less than reproducibility across hundreds of sites and a workforce with high turnover. That is precisely why fully automatic machine manufacturers are further along in networking than the portafilter market: their customers have demanded fleet management, consumption reconciliation and remote parameterization for years.
For roasteries with hospitality customers this creates a concrete approach. If you think beans, recipe and machine data together, you can not only supply coffee to a chain customer but also prove recipe adherence across their locations. That is an argument that carries weight in price negotiations.
Worked example: three tons annual consumption
Starting point: 3.000 kilograms of espresso beans per year, target recipe 18 grams in the double portafilter, actually processed on average 19 grams. 350 opening days.
Block 1: the systematic overdosing
| Item | Value |
|---|---|
| Shots at 19 g | 157.895 |
| Target consumption at 18 g | 2.842 kg |
| Extra consumption | 158 kg per year |
| Share of annual volume | 5,26 Prozent |
| 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 Euro per kilogram; binding gastro 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 measurements are lacking: three calibrations per day, each 2,5 test shots, 19 grams per shot, 350 opening days. Result: around 50 kilograms per year and grinder, i.e. about 1.100 to 1.450 Euro cost of goods. This exact amount is directly addressed by sync systems because the correction is continuous and without a test shot.
What of it reaches EBIT
Together both blocks make around 208 kilograms or just under 7 percent of annual consumption, in cost of goods about 4.600 to 6.000 Euro per year. This amount is the honest part of the calculation: it is a real cost saving and directly impacts the result.
Often people additionally calculate lost revenue: 208 kilograms would yield roughly 11.500 additional espressos at 18 grams in arithmetic. That number is correctly calculated but not suitable as an EBIT effect because it assumes that demand exists and because milk, staff, energy, taxes and other variable costs must be accounted for. If you argue internally with this lever you should treat the cost of goods as the reliable figure and explicitly label the revenue calculation as an upper limit.
There are two more effects that are hard to quantify but real: saved work time for daily adjustments and fewer complaints due to fluctuating quality.
What Sync cannot do
A control loop of time, weight and flow does not recognize why a shot is bad. Channeling, uneven distribution in the basket, tamping mistakes, 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 craftsmanship error by an incorrect grind size and conceals it.
Nor does the automation replace the initial setting. Each of these systems needs a cleanly dialed-in starting recipe that is set by taste. The technology holds the once-found point; it does not find it.
And it needs data points. With low throughput a system learns more slowly, weights individual outliers more heavily and economically saves too little waste and labor. An operation with a handful of shots per day is the wrong use case.
The counterarguments
- Cloud dependency: Systems that communicate via manufacturer platforms lose their sync and management functions during network or platform outages. What functionality remains after contract end or platform deprecation is rarely regulated publicly by any provider. This question should be included in writing in the procurement process.
- Closed ecosystems: Most systems work only 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‑machine control loops are not documented.
- Lack of price transparency: Subscription costs, activation, retrofitting and interface access are only quoted on request by most providers. Uniform monthly cloud prices per machine are not publicly available.
- Sensor maintenance: Integrated scales must remain clean, mechanically unloaded and calibrated. For grind-by-weight grinders offset corrections are required to compensate for residual flow. The technology therefore creates a small maintenance overhead itself.
- Data protection: Server location, role and rights model, data export, deletion periods, data processor agreements and behavior at contract end should be asked directly from the provider before procurement. These details are not fully publicly available for most platforms.
- Retrofit: ADAPT is installed ex works with its own software, additional memory boards and cable connection and cannot be retrofitted. Sanremo excludes connecting machines prior to the D8 series. Networking is therefore usually a decision at the time of purchase, not afterwards.
Classification by operation type
| Operation type | Sensible approach | Reason | With us for that |
|---|---|---|---|
| Café, single location, fixed team | Grind by Weight, optionally an 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 crew. | Mahlkönig E65W GbS (2.350 €) or E80W GbS (2.999 €), in combination with an approved 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 real value contribution. | Dalla Corte DC One (3.199 €) or DC Two (5.499 €) with an XT or Artisan |
| Chain restaurants | Fully automatic machines with mature fleet platform and interface | Reproducibility, remote parameterization and integration with existing systems rank above 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. Needs stable Wi‑Fi and a fixed place in the workflow. | Mahlkönig Sync Scale (250 €) |
| Roastery with hospitality customers | Know compatibility with the customers' machine park and sell it as add‑on | Recipe adherence across customer locations becomes a sales argument for the bean. | No device, but consultancy. Talk to us, we know the approval lists. |
| Office and self‑service | Grind by Weight or closed loop, depending on throughput | Changing operators without instruction 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 mostly 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 connected but whether it actually controls or only advises, whether it works without the internet and what remains after a cloud contract expires.
If you are looking to get started without replacing your machine park, start with measurement technology. The scale is the foundation of all these systems, it is the only manufacturer-independent retrofittable component, and it costs a fraction of a new machine. Knowing dose and output amount is the first step; having them corrected automatically is the second.
The economically reliable lever is cost of goods: one systematically overdosed gram costs an operation with three tons annual consumption roughly 3.500 to 4.600 Euro, the daily dial-in waste another roughly 1.100 to 1.450 Euro. Everything beyond that, especially revenue calculations based on saved coffee, should clearly be labelled as an upper limit.
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 or beverage weight, back to the grinder. The grinder compares these values with the stored recipe and either corrects the grind size automatically or shows the needed correction.
How do Mahlkönig Sync and Fiorenzato ADAPT differ?
Mahlkönig Sync adjusts the grind size motorically itself and operates in the La Marzocco combination via Wi‑Fi and cloud, with Sanremo via cable. Fiorenzato ADAPT works cabled and offline, compares the water amount from the machine flowmeter with the grind size and gives the operator an adjustment recommendation after three deviating shots, which is implemented manually.
Does Grind by Sync need an internet connection?
That depends on the system. Fiorenzato ADAPT and the cabled 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 does a Sync system pay off?
There is no universally valid threshold publicly documented. The systems regulate via averages of several shots and therefore need continuous operation. In places with steady business and changing staff the benefit is greatest; with only a few shots per day the economic effect is negligible.
Can I retrofit my existing grinder?
Generally no. Fiorenzato ADAPT is only available ex works because the grinders have their own software, additional memory boards and a cable connector; a software update is not sufficient. For Sanremo machines prior to the D8 series cannot be connected to the IoT platform. An exception is the Mahlkönig Sync Scale, which serves as a data source for machines without their own interface; the grinder itself must be a grind-by-sync model.
Is a scale enough instead of a Sync system?
It depends on the goal. A scale in the grinder secures the dose, a scale under the portafilter makes output amount and flow rate visible, and a networked scale like the Mahlkönig Sync Scale provides the data for a control loop. What a standalone barista scale does not do is the correction itself: it shows the deviation but does not adjust grinder or machine. For operations with a fixed team that is often sufficient; for changing staff the control loop is the more reliable route.
What does IoT in the coffee machine bring for maintenance?
Service is based on actual load instead of a fixed calendar interval. Brew and grind cycles, cleaning history and filter throughput determine the next appointment. Because the technician knows error codes and operating history before departure, the likelihood of a second visit decreases. An on‑site visit in Germany based on published service price lists is about 200 to 260 Euro net excluding spare parts.
Which data does a connected coffee machine capture?
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 agreements should be checked with the provider before procurement, as these details are mostly not fully documented publicly.
Does automatic grind size control replace the barista?
No. The systems hold a once-dialed-in point; they do not find it. Initial setup and sensory evaluation remain the human's responsibility. Distribution and tamping errors and channeling are not recognized by a control loop based on time, weight and flow.
