The La Marzocco Strada S 2.0 ABR represents the most sophisticated approach to automated espresso dosing without crossing into the advanced profiling territory of the Strada X. While traditional volumetric systems measure water input via flow meters, the ABR measures what actually matters: the weight of liquid espresso in the cup. This distinction elevates consistency in operations serving multiple origins, varying roast profiles, or seasonal coffees where density changes affect extraction.

Integrated scales in the drip tray weigh espresso yield in real-time during extraction. Program your target output weight—perhaps 36 grams for your 1:2 ratio signature espresso, 40 grams for a single-origin brew, 50 grams for a lungo. Press the corresponding button and the machine monitors the scales, stopping extraction precisely when the target weight is achieved. Coffee density variations, puck preparation differences, grind adjustments—none of these affect output weight consistency because the scales measure actual liquid, not water input.

The weight-based automation builds on La Marzocco's proven multi-boiler platform. Each group has its own PID-controlled coffee boiler, accurate to 0.1 degrees Fahrenheit. The separate 8.2-liter steam boiler provides consistent steam pressure. Pre-infusion can be programmed per button. The thermal system is proven and reliable—the measurement system is simply more accurate than traditional flow meters. This is precision layered on precision.

ABR models include IoT connectivity and Grind-by-Sync capability. The machine can communicate target dose information to compatible Mahlkonig grinders, creating a closed feedback loop: the grinder doses based on the machine's recipe, the machine extracts to target weight. This integration reduces setup time when changing coffees and improves consistency across your team. Modern connectivity serving practical workflow efficiency.

Handbuilt in Florence, Italy, where La Marzocco has been advancing commercial espresso technology since 1927. The ABR isn't about adding features—it's about improving accuracy where accuracy matters most: in the cup.
