Designed for Extremely Low Retention The Eureka Oro Single Dose V1.1 was engineered from the ground up to minimize coffee retention and maximize freshness. Its ELR (Extremely Low Retention) system combines several innovative features, including: 15° inclined grinding chamber Optimized coffee exit chute Internal sweep chamber design Bellows-assisted cleaning system Short coffee path Together, these features help reduce retention to less than 0.2 grams, ensuring that nearly every gram of coffee reaches your cup instead of remaining inside the grinder. For coffee enthusiasts who regularly switch between different coffees or brew methods, this low-retention design helps eliminate stale coffee contamination while minimizing waste. Bellows "Blow Up" Cleaning System The Oro Single Dose V1.1 features Eureka's integrated Blow Up Bellows System, designed to purge any remaining coffee from the grinding chamber after each dose. Simply press the bellows following the grinding cycle to clear residual grounds from the burr chamber and chute. Benefits include: Cleaner grinding chamber Improved dose consistency Fresher coffee Minimal coffee waste Easier daily maintenance Professional 65 mm Diamond Inside® Burrs At the heart of the grinder are Eureka's professional 65 mm Diamond Inside® hardened steel flat burrs. Diamond Inside® is Eureka's patented thermal treatment process that dramatically increases burr durability while maintaining consistent particle geometry over an extended lifespan. Advantages include: Excellent grind consistency Superior flavour clarity Long-lasting cutting performance Reduced burr wear Professional-level particle distribution With an estimated service life of approximately 1,000 kilograms of coffee, these burrs can produce roughly 50,000 espresso preparations before replacement is typically required under normal home use.
