I’ll be honest—I was skeptical when I first unboxed this AMZCHEF electric coffee grinder. At around $89, it costs about the same as many manual hand grinders, but promises one-button convenience for every brewing method.
After weeks of daily testing, though, this budget grinder actually performs way better than I expected.
Here is my full review of the AMZCHEF Coffee Grinder on my YouTube Channel.
Where to Buy?
It’s available on Amazon and AMZCHEF Official Store.
What You Get in the Box
The AMZCHEF comes surprisingly well-equipped for its price point. Here’s what impressed me most about the accessories :
- Bean hopper with twist-lock mechanism
- Bellows for reducing retention during single dosing
- Magnetic grounds chute that removes easily for cleaning
- Two portafilter holders (54mm and 58mm compatibility)
- Catch cup with airtight lid for storage
- Cleaning brush and basic tools
Installation takes about 30 seconds—just twist the hopper into place until it locks.
The portafilter holders snap on magnetically, though I discovered they only work with 3-tab portafilter designs.
My standard E61 two-tab portafilter didn’t fit, which was a bit disappointing.
When you’re not using the portafilter holder, it stores magnetically on the grinder’s back.
The catch cup also comes with a vacuum-sealed lid that transforms it into an airtight storage container, perfect for preserving coffee beans or pre-ground coffee to maintain freshness.
It’s these thoughtful design touches that make this feel more premium than its price suggests.
Build Quality and Design
The black and gold color scheme looks surprisingly modern for a budget grinder. Yes, the body is all plastic, not surprise for a budget coffee grinder, but it’s a nice matte texture that feels solid in daily use.
The grind adjustment dial offers 75 different settings, definitely enough for all home brewing methods. You adjust by turning the hopper, which covers everything from Turkish coffee powder to French press coarse.
The timer dial goes up to 60 seconds maximum with clear markings.
I love the little LED light under the chute when grinding. It’s a small touch, but it adds to the ritual of making coffee and looks good at night.
The 40mm Conical Burr System
Remove the hopper and you’ll see the heart of this grinder: a 40mm stainless steel conical burr with six cutting edges. The outer burr removes easily for cleaning, and there’s a safety feature that prevents grinding when opened.
The burr geometry works surprisingly well across different grind sizes.
As CNC cutting technology has gotten more sophisticated, I’ve tested dozens of coffee grinders and found that the differences between them are actually getting smaller and smaller. This burr really doesn’t differ that much compared to many more expensive machines.
At 450rpm, it keeps heat generation low, which helps preserve those essential coffee oils.
Real-World Grinding Performance
I’ve tested this grinder extensively across different brewing methods, and here’s what I found:
Ultra-Fine (Setting 1): Produces powder-like consistency good for Turkish coffee
Espresso (Setting 10): Creates fluffy, uniform grounds that work beautifully with non-pressurized baskets
Moka Pot (Setting 25): White sugar texture that extracts rich, thick crema
Pour Over (Setting 40): Decent uniformity with some fine particles for fuller body
French Press (Setting 60): Coarse enough for proper extraction without over-grinding
The grinding speed averages about one gram per second, so 18 grams for espresso takes roughly 20 seconds.
Manual hand grinders usually take 40 seconds to over a minute to grind for espresso, so electric grinders definitely have a big advantage when it comes to convenience.
Retention Test Results
Here’s where this grinder really surprised me. Using 19.4 grams of medium-fine ground coffee without any water spraying:
- Grinding time: 20 seconds
- Final retention: 0.2 grams after using the bellows
- Chaff management: Minimal mess during grinding
That 0.2-gram retention is genuinely impressive for any grinder, let alone one under $100.
Espresso Performance Testing
I paired this grinder with both entry-level and higher-end espresso machines to see how it performs.
With Pressurized Baskets: Set between grind 15-20 for forgiving extraction with rich crema
With Non-Pressurized Baskets: Setting 10 works perfectly for 18g doses
Using an 18-gram dose with a bottomless portafilter, I consistently achieved:
- Extraction time: 33 seconds for 36 grams out
- Smooth extraction with minimal channeling or spraying
- Authentic espresso flavor suitable for milk drinks
The spent puck looked well-extracted, and I pulled many successful shots. For a grinder under $100, this level of espresso capability is quite surprising.
Pour Over and Other Brewing Methods
At setting 40, the grind uniformity works well for pour over, though you’ll notice some fine particles that add body to the cup. If you’re used to pre-ground coffee, the flavor improvement with fresh grinding will be immediately noticeable.
For moka pot at setting 25, I consistently extracted rich aroma and thick crema—much easier than using a manual hand grinder for the same result.
The Bottom Line
For coffee lovers just starting their home brewing journey, or anyone who doesn’t want to spend big on coffee gear yet, this AMZCHEF grinder delivers solid value. The grinding performance genuinely impressed me across all brewing methods.
Pros:
- Excellent retention performance (0.2g)
- 75 grind settings cover all brewing methods
- Thoughtful accessories and design
- Capable espresso grinding at $89 price point
- Easy cleaning and maintenance
Cons:
- All-plastic construction
- Portafilter holder only fits 3-tab designs
- Some fine particles in medium grinds
The plastic construction is really the only significant downside, but with normal use, it shouldn’t cause problems. At this price point, you’re getting performance that genuinely competes with grinders costing significantly more.
