Frequently Asked Questions
What does a coffee system do?
A coffee system, particularly a connected system like The Sync System, communicates between coffee equipment via IoT applications optimizing the espresso brewing process. It aims to:
- Automate grinding and brewing: Connects the grinder and espresso machine or Sync-enabled device to ensure seamless communication and automated workflows via the Mahlköng Sync app.
- Ensure Consistency: Maintains consistent grind size, dose, and brewing parameters for repeatable results.
- Optimize Workflow: Streamlines the barista's workflow, reducing manual steps and improving efficiency.
- Improve Coffee Quality: By precisely controlling grinding and brewing recipes, it enhances the extraction process and overall coffee quality.
- Data & Information Monitoring: When onboarded to the Mahlkönig Cloud via the Mahlkönig Sync app, The Sync ecosystem allows for data collection from grinder to cloud and automatic software updates from the cloud to the grinder. This seamless integration can be used to monitor grind and brew events, equipment usage, predict maintenance and improve workflow.
What espresso machines and grinders are compatible with The Sync System?
Currently, our coffee solution integrates with:
- Commercial Espresso Grinders: Mahlkönig’s Grind-by-Sync series, including E65W GbS, E80W GbS, E65T GbS and E80T GbS
- Commercial Espresso Machines: La Marzocco compatible machines in AV or ABR configuration*, such as Strada S, KB90, Linea PB, Linea PB X, Linea Classic S, GB5 S, GB5 X *Only available in the United States and Australia
These models have been specifically engineered to communicate effectively via Wifi to the IoT cloud connectivity allowing the machine to send brewing data to the grinder (The Sync System), enabling features like automated grind adjustments and dose control to ensure alignment with the recipe parameters. This integration ensures a high level of consistency and efficiency in your espresso preparation.
How does The Sync System help prevent maintenance issues with GbS grinders?
The Sync ecosystem helps to address potential maintenance issues by monitoring key performance indicators within your Grind-by-Sync espresso grinder. Leverage data reports for grinding events and burr usage, to provide insights on your daily operations. Access the reporting dashboard via the Mahlkönig Sync Desktop App for a more detailed view of your data. Use the Mahlkönig Sync Mobile App for iOS or Android an on-the-go business view and to receive notifications for updates and alerts.
Here's how it works:
- Real-Time monitoring: The system constantly tracks critical parameters like burr wear and grinding consistency.
- Predictive alerts: Based on the collected grinding data, the system displays information that can support operational decision making and equipment maintenance. By addressing potential issues before they escalate, The Sync System minimizes downtime and ensures consistent grinder performance, reducing the need for frequent manual disassembly and potential repairs.
How does the Sync System algorithm work to make automatic adjustments to the grind size?
The Sync System reacts to data it receives via cloud communication from the espresso machine concerning extraction times. That means the Sync System will adjust the grind size whenever necessary. In some instances, it might not make any adjustments for an entire shift if the shots stay true to the recipe brew time parameters. In some situations, the grinder might adjust the grind size multiple times to stay on recipe. The algorithm will adjust based on the results of the last 5 shots. If the brew time parameters are off across the last 5 shots, it will make a burr size adjustment.
If the shot runs too fast, indicating a coarse grind, the algorithm within the grinder signals the electric motor to refine the disc distance which therefore adjusts the grind size. If the shot is too slow, indicating a fine grind, the grinder adjusts to a coarser grind size. The Sync System uses the target extraction time of the espresso machine to automatically adjust the disc distance on the grinder.
What is the main advantage of the Sync System?
The quality of a coffee beverage is subject to the variance of several parameters during the brewing process such as the roast of coffee beans used, equipment stability, and environmental conditions, like temperature and humidity. The Sync System is the first connected coffee system that brings automation to traditional espresso grinders and espresso machines. While there are some super-automatic espresso machines that advertise similar features, the Sync System has two major advantages: precision and control. Because the Sync System combines grind and brew event information, it’s the only automated grind adjustment system that offers the same level of recipe precision as manually adjusting your espresso grinder.
Grind-by-Sync (GbS) is an innovation brought to the newest Mahlkönig espresso grinder range. When connected to the Sync ecosystem, GbS grinders automatically adjust the coffee grind size to achieve the target brew time, which is set within the recipe. The grinder receives the espresso brew time from the coffee machine and intends to keep the brew time within a tight range of the recipe parameters by considering the brew time variances and adjusting the grind size accordingly.
The Sync System is most accurate with the weight-based espresso grinders incorporating the load cell scale as this eliminates one major variant, the weight variance of the ground coffee: These grinder models are the E65W GbS and the E80W GbS.
The Sync technology is also available with our time-based espresso grinders, using an algorithm to adjust the time when the grind size is changed, to help maintain the coffee weight output: These grinder models are the E65T GbS and the E80T GbS.
