The DF54 Grinder is a 54mm flat burr, single-dose grinder designed for precision espresso grinding. After testing it extensively with my HiBrew H10 Plus, I found it to be an exceptional grinder for home baristas looking for fine control over their espresso extractions. With stepless adjustment, low retention, and excellent grind consistency, this grinder delivers a professional-level grinding experience at an affordable price.
The 54mm flat burrs provide a highly uniform particle size distribution, which is critical for balanced espresso extraction. Flat burrs are known for producing a cleaner and more defined flavor profile compared to conical burrs, and the DF54 does an excellent job at this. The stepless adjustment system allows for precise control over grind size, making fine-tuning espresso shots effortless. Unlike stepped grinders, which limit grind size adjustments to predefined increments, the DF54 lets you make micro-adjustments, ensuring optimal flow rate, pressure, and extraction time.
A major advantage of the DF54 is its low retention design. The grinder retains very little coffee between doses, ensuring precise and repeatable extractions.
Retention Rate: Negligible (Less than 0.2g per dose). If you want absolute zero retention, a quick puff of air (bellows) can remove any remaining grounds from the chute. Static buildup is minimal, though slight static can occur in dry conditions. This can be mitigated using Ross Droplet Technique (RDT).
My final verdict : The DF54 Grinder is an excellent choice for home baristas looking for a precise, low-retention, and highly consistent espresso grinder. The stepless adjustment, high-quality burr set, and solid build make it one of the best budget-friendly flat burr grinders on the market. Delivers exceptional grind consistency and control, making it a must-have for serious espresso enthusiasts! 🚀
