【Grinding in Seconds with Near-Zero Retention】
Initially skeptical about electric conical burr grinders, Justin was pleasantly surprised after testing the A68, describing its performance as "impressive."
He noted that despite its compact size, the A68 features a large 68mm conical burr, capable of grinding for pour-over in 15 seconds and espresso in about 30 seconds[1].
The A68 is user-friendly, requiring only the addition of coffee beans from the top and a press of a button.
As for noise levels, the A68 runs at approximately 70 dB when idle and can reach up to 80 dB while grinding.
Justin remained neutral on this aspect, emphasizing that the acceptability of noise is subjective and varies by personal preference.
He also highlighted the grinder’s anti-retention design, where the grind chute beneath the burr chamber assembly rotates synchronously to remove residual grounds, ensuring all coffee falls directly into the grind cup.
Once grinding is complete, a simple tap on the cup collects all the coffee grounds, achieving near-zero retention.

【Tool-Free Disassembly – As Easy as Playing with a Toy】
Justin pointed out that all parts of the A68 are magnetic design, allowing for effortless tool-free disassembly.
He found the design not only practical but also enjoyable, admitting that he repeatedly took the grinder apart like a toy and even joked that "it’s so easy to assemble that it scares me!"
One potential drawback is the slightly big power adapter, which may not be ideal for users with limited counter space or those without a dedicated coffee station[1]. However, as someone who values grinder design, Justin was particularly impressed by these two structural features of the A68:
-
Motor-Burr Isolation Design – This prevents motor vibrations from affecting burr stability, ensuring consistent grinding.
-
Dual-Bearing Burr Support – The burr assembly is reinforced with upper and lower bearings, securing the inner burr’s axis and preventing wobbling, which enhances flavor consistency.

【0.008mm Precision Adjustment – Effortless Switching Between Pour-Over and Espresso】
The A68’s grind adjustment mechanism is designed with stepped settings, allowing precise 0.008mm micro-adjustments per step and offering three full rotations in total[1].
Based on Justin’s experience, the ideal grind size for espresso falls between 70 - 80 steps, while pour-over settings are best at 170 - 180 steps. He found switching between grind sizes to be remarkably convenient.
Justin also noted that while the A68 provides excellent micro-adjustments for espresso, what matters more than just the range is the impact of each setting on extraction time.
With the A68, a single step adjustment can alter the extraction time by 2 - 5 seconds, providing espresso enthusiasts with ample control to fine-tune their brew.

【Justin’s Review: A Grinder That’s Absolutely Worth Trying】
Justin evaluated the A68’s performance in both pour-over and espresso brewing:
-
Pour-Over: Compared to manual hand grinders, the A68 delivers a more balanced and rounded flavor. The burr design enhances acidity, clarity while integrating it smoothly into the overall flavor profile. Even as the coffee cools, it still maintains an enjoyable taste.
-
Espresso: The A68 produces a velvety-smooth texture with a structured yet light-bodied profile, surpassing competitors in its class.
Justin also highlighted that the A68’s price point makes it highly competitive in its category.
While some minor coffee grounds may scatter during use, its dual-purpose capability for both pour-over and espresso makes it a versatile all-in-one grinder.
With performance rivaling high-end models, user-friendly operation, and exceptional grind quality, he concluded "The A68 is a grinder that’s absolutely worth trying!"
