【Asa - A Coffee Gear Reviewer with Masters Data Analysis】

Asa Baiz is a well-known coffee gear reviewer in the U.S. His videos are not just simple product introductions but are renowned for their professional and meticulous analysis.

Leveraging his expertise, he provides in-depth evaluations of various coffee equipment, helping viewers get the most authentic and reliable information.

Asa Baiz has nearly 200,000 subscribers on YouTube and 60,000 followers on Instagram, attracting a vast audience of coffee enthusiasts.

Unlike many other unboxing influencers, he specializes in thorough testing based on specific metrics, offering clear data comparisons to help viewers select the most suitable coffee gear.

【Tool-Free Disassembly for Easy Cleaning and Maintenance】

Asa highlights that the A68 electric coffee grinder features a sleek and understated aluminum alloy body with a solid 5.5kg build, ensuring stability during operation[1].

Additionally, its tool-free magnetic design allows users to fully disassemble the grinder within seconds.

Asa believes this feature not only enhances cleaning and maintenance convenience but also makes the A68 stand out from the crowd. He even describes this design as “super cool”[2]!

1. Large burr grinders require significant torque to crush coffee beans. If the grinder is too light, it may vibrate during operation, affecting grind consistency and quality.

2. The magnetic design enables full disassembly in just 5 seconds. More importantly, after cleaning, the burrs do not require recalibration, making it immediately ready for use.

【300+ Grind Settings to Dial in Your Preferred Flavor】

Asa points out that the A68 grinder features an adjustment dial with over 300 grind settings, with each step corresponding to a burr gap of just 0.008mm, allowing precise control over grind size for different brewing methods.

Switching between grind settings is also incredibly easy, ensuring that users can quickly find their ideal flavor profile.

Even when alternating between pour-over and espresso settings, where previous adjustments might be forgotten sometimes, Asa believes the A68’s ultra-fine grind adjustments remain one of its standout features[1].

1. Asa mentions that while the adjustment mechanism may not be the most intuitive. However, if users forget their previous settings, it only takes a few seconds to reset and recalibrate.

【Grinding & Cleaning - Stable Grinding Without Clogging】

According to Asa, the A68 grinder produces minimal fines thanks to its 192W DC motor, which operates at a low speed of 60 RPM, combined with its large 68mm burr set[1].

While this speed is lower than that of most conical burr grinders, the larger burr size compensates by maintaining high grinding efficiency, ensuring smooth and consistent performance without clogging. Based on Asa’s tests:

• At espresso grind setting: The A68 grinds 1g of coffee per second.

• At pour-over grind setting: It grinds 1.5g per second.

• The grinding process remains smooth and free from clogging.

To further combat static electricity and residual coffee grounds, the A68’s grind chute is equipped with a built-in brush that synchronically cleans the burrs as it grinds.

If users want to minimize static even more, Asa suggests using the Ross Droplet Technique (RDT) before grinding. His tests show that with RDT, the A68’s retained grounds can be reduced to less than 0.1g[2].

1. The A68 is designed for the perfect balance between grinding efficiency and coffee quality by combining 60 RPM operation with a large burr set. This prevents excessive heat buildup, which could negatively affect coffee flavor, while also supporting continuous grinding sessions.

2. If users experience static-related retention without using RDT, they can rotate the grind chute after grinding. The built-in brush will help dislodge residual ground. Then, users can remove the chute and knock it against a surface along with the grind cup, ensuring any remaining grounds fall into the cup. The cup’s base is padded to prevent wear and damage.

【Asa’s Review: Versatile, Clean Flavor, and Absolutely Worth Considering】

Asa concludes that the A68 grinder is intuitive and user-friendly, equipped with larger burrs than most competing grinders, and produces exceptionally clear flavors, making it suitable for various brewing methods. 

While the A68 is priced slightly higher than some competing electric grinders, Asa believes its premium build quality and design fully justify the cost. Overall, he finds the user experience exceptional.

Beyond its grind performance, Asa highlights the A68’s modular burr set and magnetic design, making it a strong competitor among high-end grinders.

Additionally, for those concerned about noise levels, Asa's tests show that the A68 operates at around 75 - 80 dB, which he considers within the standard range for grinders of his professional experience.

While Asa acknowledges that the power adapter’s size may be inconvenient for users with limited space[1], he doesn’t see this as a major issue, emphasizing that every grinder has trade-offs.

Given its well-thought-out design and performance, he believes the A68 has secured its place in the market, even as a newcomer brand.

Finally, Asa concludes:

“If you're looking for a versatile, high-performance conical burr grinder that delivers exceptional clarity in flavor, the A68 is definitely worth considering!”

1. To provide sufficient torque, especially for fine espresso grinding with light-roasted beans, the A68 is the only model that meets national regulatory certification while delivering high torque performance. The power cable has been intentionally extended for more convenient storage.
