For coffee enthusiasts seeking precision, the Coffmeter A1 offers a compelling blend of affordability and accuracy. This colorimeter, a subsidiary of DiFluid, measures Agtron values for both whole bean and ground coffee with surprising consistency. My initial tests revealed results that align closely with calibration tiles, suggesting the device is reliable—even if not perfect. The real test came when I compared it to Coffee Review’s Agtron data for JBC Roasters’ coffees. While whole bean readings varied by ±3 points, ground coffee consistently showed a +11 spread. This discrepancy likely stems from grind size differences, but the fact that all three samples aligned within this range is reassuring.
The device’s strength lies in its ability to quantify variance. Whole bean deviations over 4 points are flagged, while ground coffee thresholds hover around 3. The delta between whole bean and ground—ranging up to 20—grows lighter as the roast darkens. Notably, the average deviation for ground samples was just 0.1, a figure that stands out at this price point. It’s not flawless, but for a colorimeter that costs less than a single high-end grinder, it’s hard to fault.
Build quality feels solid, with a matte finish that resists fingerprints. The interface is intuitive, though the lack of a dedicated app feels like a missed opportunity. Still, the device’s core function—delivering repeatable Agtron measurements—shines through. If you’re chasing consistency in your cup, the Coffmeter A1 is a worthy contender.
Key points: The Coffmeter A1 offers affordable, repeatable Agtron measurements; grind size significantly impacts ground coffee readings; and its build quality justifies its price.
