Mahlkönig Sync – The autopilot for your espresso
Available from March 2026
For those who extract by time
Imagine this: It's 7 a.m. You take your first shot. Perfect. 25 seconds, 36g out, creamy, chocolatey, intense. You drink it. You smile. That's perfection.
It's 2 PM. You take your fourth shot. And suddenly: 18 seconds. Too fast. Too weak. The shot tastes flat, empty, somehow wrong. What happened?
The answer: Everything has changed. The temperature has risen (the sun is shining through the window). The humidity has dropped (the heating has turned on). The beans have "worked" (they have oxidized, they have lost moisture). Your perfect recipe from 7 a.m.? It won't work anymore at 2 p.m.
Normally, you'd have to intervene now. Readjust the grind. Pull a test shot. Readjust. Test again. That's annoying. That's time-consuming. That's why many cafes serve worse coffee throughout the day – not out of laziness, but because they can't keep up with the constant fluctuations.
With Mahlkönig Sync, your grinder does it automatically.
Sync is the revolution professionals have been waiting for: a direct data connection between your grinder and your espresso machine. The machine reports: "The shot was too fast – 18 seconds instead of 25." The grinder replies: "Understood, I'll adjust it finer," and automatically adjusts the burrs by a few micrometers. Without you lifting a finger. Without you even noticing. The next shot? Perfect. 25 seconds. Creamy. Full-bodied. Intense.
This isn't just technique. This is consistent perfection . This is the difference between "sometimes good" and "always brilliant".
As an official Mahlkönig partner, we bring this cloud technology to your kitchen or café. Your equipment now communicates with each other. Welcome to the future.
Why Mahlkönig Sync changes everything
The truth about espresso: Espresso isn't stable. It changes. Constantly. The temperature fluctuates (heating, air conditioning, sunlight). The humidity fluctuates (weather, season). The beans change (oxidation, moisture, age). What was perfect at 7 a.m. is too fast at 2 p.m. What was perfect in winter is too slow in summer.
Until now, the grinder and the machine were two separate worlds. The grinder ground. The machine brewed. And you? You were the intermediary. You constantly had to intervene, adjust, test, readjust. That's stressful. That's inefficient. That's why most espressos aren't consistent.
Mahlkönig Sync breaks down this barrier. It wirelessly connects compatible grind-by-weight grinders (such as the Mahlkönig E64 WS, E65S GbW or E80S GbW ) to compatible espresso machines .
The system monitors every single shot . It learns. It reacts. If the extraction time shifts—for example, because the heating element kicks in, a new bag of beans is opened, or the humidity changes—the grinder adjusts the grind size (disc distance) down to the micrometer level. Automatically. Precisely. Instantly.
You set your recipe once: 18g in, 36g out, 25 seconds. Sync keeps this recipe locked in. Forever. No matter what happens. No matter what the weather is like. No matter how old the beans are. The next shot? Perfect. The shot after that? Perfect. Shot number 100? Perfect.
This isn't science fiction. This is available. Now.
Technology in detail – How it works (and why it works)
- The data bridge: Sync uses the cloud infrastructure of Mahlkönig and La Marzocco to exchange data between devices. The machine continuously sends data (extraction time, flow rate, temperature) to the cloud. The mill receives this data and analyzes it. If a deviation is detected, the mill reacts immediately. This is an ecosystem of intelligence – your equipment communicates with each other, learns from each other, and optimizes itself.
- Automatic adjustment: The grinder features a motorized adjustment mechanism (integrated in the Mahlkönig E64 WS , E65S GbW, and E80S GbW). It physically adjusts the grind finer or coarser based on the machine's data. The adjustments are made in the micrometer range – precise, smooth, and imperceptible. You don't see it. You don't hear it. But you taste it – every shot is perfect.
- The Sweet Spot: You define your target once (e.g., 18g coffee grounds, 36g espresso, 25-second extraction time). Sync ensures you stay there. Forever. If the shot runs faster (19 seconds), Sync adjusts the grind finer. If the shot runs slower (31 seconds), Sync adjusts the grind coarser. You always drink the perfect shot – without thinking, without adjusting, without stress.
- Compatibility: Currently available for Mahlkönig E64 WS, Mahlkönig E65S GbW and E80S GbW (grind-by-weight models with motorized adjustment mechanism) in combination with La Marzocco machines (Linea Micra, Linea Mini, GS3, KB90 – all equipped with or retrofittable with an IoT module). Further compatibilities are planned – Mahlkönig is working to extend Sync to more devices.
The chemist's perspective: Why consistency is more important than equipment
Why Constance fundamentally changes taste:
For those who extract by time: An espresso only tastes brilliant if the contact time between water and coffee is correct.
If the shot is brewed too quickly (underextraction): Insufficient contact time. The valuable coffee oils (lipids) and sugars are not fully dissolved. The shot tastes thin, flat, and empty. It lacks body and sweetness. You only taste the superficial notes – but not the depth, the complexity, or what makes coffee special.
If the extraction process is too slow (over-extraction): Too much contact time. The water dissolves not only the beneficial aromas but also the unwanted bitter substances (chlorogenic acids, tannins) and astringent compounds. The shot tastes harsh, dry, and unpleasant. The sweetness is overpowered by bitterness. The mouthfeel becomes thin, not creamy.
The "sweet spot"—the perfect balance: With the right contact time (e.g., 25-28 seconds at 9 bar pressure), the valuable aromas are optimally extracted—the coffee oils for creaminess, the sugars for sweetness, the aromatic compounds for complexity. The shot tastes complete, balanced, creamy, and full. Maximum body, maximum chocolate notes—like our Nutty Delight or Cozy Chocolate .
The problem? This sweet spot is extremely narrow. A difference of 3 seconds (22 instead of 25 seconds) can fundamentally change the flavor – from perfect to weak. A difference of 5 seconds (30 instead of 25 seconds) can ruin the shot – from perfect to bitter.
Mahlkönig Sync keeps you permanently within this ideal chemical range. It prevents the fluctuations that ruin the taste. You don't just get a good espresso every now and then. You always get the perfect body and full aroma. That's the difference between luck and science. That's the difference between "sometimes brilliant" and "always consistent."

Who is Mahlkönig Sync right for? – The honest answer
For those who prefer timed extraction. Sync is high-end. Sync isn't for everyone. Sync is for people who understand: consistency is more important than perfection. Better 100 shots that are all 95% perfect than 10 shots that are 100% perfect and 90 shots that are "okay".
Treat yourself to Mahlkönig Sync if you run a café:
- When different baristas are at the machine – Sync guarantees that the quality remains the same, regardless of who is operating it.

- You're a perfectionist – Sync makes perfection the norm, not the exception.
- The budget is secondary – Sync is an investment in lasting quality, not a purchase for quick gratification.
Treat yourself to Mahlkönig Sync if you're a perfectionist:
- If you hate having to search for the grind setting again in the morning – Sync remembers what works and keeps it.
- If inconsistency bothers you – Sync eliminates the variables that ruin your espresso.
- If you understand: The best grinder in the world is useless if the grind size fluctuates – Sync turns good grinders into brilliant grinders.
- If you're willing to pay for consistency – Sync is expensive, but it's worth every penny.
Or combine it with the Mahlkönig E64 WS : If you want grind-by-weight (no more manual weighing) but aren't ready for syncing yet, the E64 WS is the perfect middle ground. Grind-by-weight + manual adjustment = maximum convenience without cloud dependency.
