The La Marzocco Strada S ABR 3 Group represents the cutting edge of precision espresso automation. Combining all the benefits of auto-volumetric dosing with integrated drip tray scales, this machine delivers weight-based accuracy that flow meters simply can't match. With capacity for high-volume commercial operations and three independently controlled brew groups, the ABR eliminates variables and delivers exact brew ratios every single time. The ABR auto brew ratio system measures what actually matters - the weight of liquid espresso in the cup. While traditional volumetric systems measure water going in, the ABR measures espresso coming out. This distinction is crucial because coffee density, puck resistance, and roast level all affect how much liquid you get from a given water volume. Set your target to 36 grams, and the ABR delivers exactly 36 grams - not 34, not 38, but precisely 36 grams. Every shot. Every time. This weight-based precision ensures your 1:2 brew ratio remains constant regardless of coffee variations, grind adjustments, or environmental changes throughout the day. The integrated drip tray scales measure espresso weight in real-time during extraction. The system stops automatically when the target weight is reached, accounting for coffee density differences that would throw off volumetric measurements. This makes the ABR especially valuable for cafes running multiple single-origin coffees where density variations between roasts would otherwise require constant recipe adjustments. Program once, get consistent results across different coffees. The ABR is also IoT-equipped with Grind-by-Sync compatibility, allowing communication with Mahlkönig grinders for complete dose-to-yield precision from grinder to cup. Three individual PID-controlled boilers provide independent temperature zones for each group. Light roast at 201°F on group one, dark roast at 197°F on group two, decaf at 199°F on group three - all simultaneously with precision to 0.1 degrees Fahrenheit. The 11.8-liter steam boiler ensures continuous steam power during peak service. And at just 19.7 inches tall, the low-profile design creates an inviting workspace with expansive drip tray area (integrated scales don't reduce workspace), improved sightlines, and the customer engagement opportunities that define modern specialty coffee service. Handbuilt in Florence, Italy with 95+ years of La Marzocco expertise, the Strada S ABR combines Italian craftsmanship with advanced automation technology. For specialty cafes where precision brew ratios define quality, for multi-roaster operations requiring consistent results across varying coffee densities, for high-volume cafes refusing to compromise accuracy for speed, the Strada S ABR 3 Group delivers weight-based consistency that represents the future of commercial espresso automation.
