Domestic Coffee Machine Building Blocks Review: Which Brand of Coffee Machine and Grinder Works Best?

Hello everyone!

Your friendly neighborhood wallet-draining reviewer Ari is back! This time! I've spent a fortune!!!!!!!!!!!!!!! buying ten popular coffee machines and grinders on the market, worth hundreds of thousands of dollars!

Building blocks! Hahahahaha

It took me a whole week to experience the joy of assembly! Did everyone recognize which brand and model of machine this is?!

Here's the story: as a writer who follows the coffee industry, my antenna is highly sensitive to coffee peripherals! So shortly after these coffee machines and grinders launched, I managed to get my hands on all of them. But I was busy with other things, so the assembly project sat on hold. Until... one day my cat clawed open one of the boxes and started playing with a bag of parts - that's when I finally got to work (I'm not lazy! really).

This time I bought coffee peripherals in 5 series: "Sicily Late Autumn Collection," "Midsummer Green Collection," "Roman Holiday Collection," "Venice Summer Evening Collection," and "Milan Early Spring Collection."

Basic model - "Milan Early Spring"

The coffee machine here is modeled after the Rocket R58, and the grinder after the EK43. The avocado green and light pink color scheme looks fresh overall, and the small number of parts makes it beginner-friendly. Once assembled, it's compact and takes up little space. The real Rocket R58 suits home use and small-to-medium coffee shops: its classic E61 brew head no longer fixes the distribution screen with screws, giving more even, stable water flow, and the internal dual boiler plus rotary pump provides better stability for extraction and steam.

Everyone surely knows the EK43! It's practically standard equipment at specialty coffee shops and pour-over-focused cafes. This grinder uses 98mm alloy steel parallel burrs, delivering the power for faster, more uniform grinding that preserves as much bean aroma as possible. One EK43 can also be set to different grind sizes, handling everything from pour-over to espresso.

Advanced Model - "Venice Summer Evening Collection"

The coffee machine here is modeled after the Slayer Steam EP, the grinder after the Mythos One. The lake green and goose yellow palette looks bright and refreshing, and the higher parts count suits builders with daily patience! Assembled, the size is reasonable and doesn't crowd a room. The Slayer Steam EP fits specialty shops and high-volume cafes: electronically controlled brew heads and a professional steam system finely regulate steam volume, temperature, extraction uniformity, and brew temperature, while the multi-boiler control keeps temperatures stable across consecutive shots.

The Mythos One is an espresso grinder with 75mm inclined flat burrs that minimize retained grounds. It also heats and holds a constant temperature, reducing the effect of ambient temperature swings on grinding and preserving bean flavor - though that feature can accelerate flavor dissipation in the hopper, so low-volume shops shouldn't stock too many beans in it.

Advanced Model - "Midsummer Green"

The coffee machine here is modeled after the La Marzocco GS3, the grinder after the Ultra. Light brown and grass green give it the look of a fresh summer lawn. Like the Venice set, it has plenty of parts and demands patient daily building! After assembly there are 4 pieces in total. Although the "wires" behind the grinder look realistic, they're somewhat impractical and come loose easily.

The La Marzocco GS3 is the "little darling" of many coffee people! It suits home use and small-to-medium cafes. The saturated brew head guarantees water temperature reliability and extraction stability, the steam wand uses a layered anti-scald design, and the internal dual boiler sustains stable temperature and steam through continuous cup output.

The Ultra grinder may be relatively uncommon domestically, but it's designed by domestic designers and produced domestically, primarily for export. Its strength lies in the 98mm HU burrs: large burrs deliver higher grinding capacity per unit time, reducing heating of the coffee and preserving more flavor. It also features an independent click controller that adjusts rotation speed and even lets you program grinding speeds.

Patience Model - "Roman Holiday"

The coffee machine here is modeled after the Black Eagle VA388, the grinder after the LWW EG-1. Brown and light brown give it a steady, mature look. There are quite a lot of parts, and the similar colors between pieces make sorting them during assembly genuinely mind-taxing!

Assembled, it's neither too big nor too small. The Black Eagle VA388 suits specialty shops and high-volume cafes: the T3 temperature control system layers three stages of temperature management from boiler to brew head, ensuring consistency and preventing water temperature swings from affecting taste, while a built-in high-precision scale precisely controls liquid yield.

The LWW EG-1 looks rather like a microscope and uses DB2 dual-peak burrs that make single-origin flavors pop after grinding. The burrs mount magnetically, and the cylindrical design ensures no grounds linger in the burrs or grinding chamber. You get infinitely fine grind adjustment plus burr speed control.

Patience Model - "Sicily Late Autumn"

The coffee machine here is modeled after the Kees Speedster, the grinder after the Mazzer Super Jolly. Maple leaf red and goose yellow give it a full late-autumn mood. The parts count is high but assembly isn't hard - easier than Roman Holiday. Assembled, it's neither too big nor too small. The Kees Speedster suits specialty shops and high-volume cafes: an independent PID temperature control system and self-circulating saturated brew head keep brewing stable, and an extraction lever allows manual pressure adjustment - a machine that combines automatic and manual modes, letting baristas chase extraction pressure to their heart's content.

The Mazzer Super Jolly is an espresso grinder with 64mm high-hardness carbon steel flat burrs. The built-in grinding flow control system (GFC) cuts down static and prevents clumping, while dual fans keep the grinding chamber from heating up, maximizing aroma preservation.

Final Thoughts

And that's the tour of these original building-block coffee machines and grinders!

Domestic building blocks have come a long way in recent years, both in design and in the fit between parts. The edges and corners of the pieces still need refining, though.

Among these sets, some individual parts fit poorly, leaving gaps between assembled pieces, or components with insufficient support that come loose after assembly. Missing parts occasionally happen too.

If you're not OCD about perfection, it's really not a problem! Personally, I think the cost-performance ratio is acceptable!

My fingers just hurt a bit after finishing!!

FrontStreet Coffee Recommendation

After all this talk of EK43s and flat burrs, remember the point of a good grinder: unlocking a good bean's full flavor. If you're grinding fresh at home, FrontStreet Coffee's Queen Estate Yellow Bourbon is a wonderful all-rounder - sun-dried for pronounced sweetness, medium-roasted to show nuts, cream, and sugarcane with soft fruit acidity, at home in any brewer from pour-over to espresso machine.

For brighter cups, FrontStreet Coffee's Yirgacheffe Natural Red Cherry offers mature fruit aroma, lively fermentation and berry notes, then citrus acidity and a juicy grape finish, while the Mozart from the Musicians series - a raisin honey-process Costa Rican - layers Kyoho-grape sweetness with pineapple, osmanthus, rose, and winey fermentation notes. Feed your freshly assembled grinder beans like these, and every test shot becomes a pleasure.
