Introducing the Eureka Mignon Brew Pro 55.
Eureka is one of the bigger brands in the world when it comes to quality grinders. Not only are they the manufacturers of the Olympus and Atom grinders, Eureka is also responsible for the mechanics behind the Victoria Arduino grinders like the Mythos one and Mythos 2. Although these grinders are more set for commercial use, Eureka has not forgotten the consumers market by producing the Eureka ‘Mignon’-line. This line of grinders consists out of several models: Silenzio, Magnifico, Specialita’ and Perfetto. All of these grinders have one characteristic in common that makes these grinders in such high demand all over the world: Silent Technology. This technology is created and patented by Eureka and delivers an almost silent grinder. Pretty awesome huh?
The grinder that Eureka send to me is the Eureka Mignon Brew Pro 55. Although it looks exactly like the Perfetto, Specialita’ and Magnifico series, there is one huge difference. This grinder is created specifically for pour-over and drip coffee. This grinder covers the range from the Siphon to the French Press and uses specifically created ’55mm burrs. I was really excited to test this grinder; most of my reviews are pour-over and drip coffees after all.
The first thing you will notice on this grinder is the modern clean look it has. The sharp angular lines of the grinder make it look like an accessory on your counter top or in your living room and kitchen. The display has adjustable lighting and the touchscreen reacts perfectly to your touch. The hopper is in line with the modern clean look of the grinder and can hold up to 300gr of beans at the same time. The grind size adjustment dial is sturdy and not too small. Operating the dial is as easy as you’d expect when looking at it. Included with the grinder is a plastic grind container that catches all the ground coffee that you produce, so no more sprudge! And since we’re mentioning sprudge; Eureka’s ACE system makes sure that the electrostatic charge of the coffee is eliminated. This system made sure that I didn’t find any clumps of coffee in the container after grinding during the testing period. Unfortunately the container ‘rests’ against the grinder and is easily bumped over. There is no ‘fork-holder’ for a portafilter since this grinder should not be used for espresso brewing.
Grinding with the Brew Pro.
The Brew Pro offers several option when it comes to grinding. First you can choose between a single of double dose, or you can choose the continuous mode. The grinder offers the option to adjust your grind time according to your need. The Brew Pro can grind between 1.9gr to 2.5gr per second depending on the coffee that you’re grinding. I found out that the grinder grinds 18gr per 7.5 seconds but I use 8.5 seconds just to be sure. The single dose setting can grind for 30 seconds straight (75gr of coffee per dose) and the double dose setting can dose for 50 seconds straight (up to 125gr of coffee per dose). Ideal settings for shops that sell pre-ground filter coffee.
When using the continuous grind setting, you will have to nudge the grind button with the container to start and to stop the process.
Setting up the Eureka Mignon Brew Pro is fairly easy. Plug the power plug in, put the hopper in the machine and turn it on. Just like any other grinder, it took me quite a lot of beans to get the grind setting right at the start. Since all new grinders ‘eat’ coffee the first time they’re being used, that did not came as a surprise to me at all.
When I first started grinding I was completely surprised by the almost silent grinding. Usually my wife stares at me angrily when I grind coffee during the evening news, but now she didn’t even notice it. Before I knew it, the 18 grams of beans were dispersed into the plastic container. When pouring the ground coffee out, I noticed that some flakes did stick to the plastic container. It wasn’t all that bad though and the ground coffee did not stick at all. So the grinding with the Eureka Brew Pro 55 is as easy as it comes.
The quality of the ground coffee is nothing short of amazing. Be it with the grounds for the Siphon, Aeropress or Hario V60, I have no complaints whatsoever. Brewing times shifted a lot when I started using this grinder. With the Minos hand grinder or Fiorenzato F64 I brewed 15gr/225gr in 2 minutes flat. With the Brew Pro I suddenly found myself at 1:50 minutes while using the same particle size. I had to change my grind size considerably and, in return, got brews that were so much better than before! But what about the consistency, ‘fines’ and retention of the grinder?
Consistency, retention and ‘Fines’
The dial for the grind size comes with the SMRS system (Stepless Micrometric Regulation System) which is patented by Eureka. This system is the only one that moves the lower burr and ensures infinite adjustment points. This systems works absolutely perfect. But I wanted to know how consistent the system is, how much retention you get and the amount of fines you have in a single dose. Therefore I divided the dial settings into four settings: number 0.1, number 3, number 6 and the number 9.
Within these settings I performed three tests to get the results on how the Brew Pro holds itself in terms of consistency, ‘fines’ and retention.
Below you will see the photos of the particle consistency test on these four settings. As you can see on the photos, the consistency is great. In the coarser 9 setting you will see some inconsistency but not overly much. On the 0,1 there is hardly any inconsistency at all. I was very pleased with these results on the Brew Pro.
The next test was the retention test. For the retention test I grounded 20 grams of coffee beans on each setting. I let the machine grind for 15 seconds each time.
- 0.1 setting gave 0.3 grams of retention
- 3.0 setting gave 0.2 grams of retention
- 6.0 setting gave 0.1 grams of retention
- 9.0 setting gave 0.1 grams of retention
That’s not so bad for a grinder! I was kind of impressed especially since I got 0.0 retention on the grinding a few times on the 6.0 and 9.0 setting. Since it did not come up continuously I decided not to publish those as exact results. I guess the ACE system is doing it’s job pretty good. For the fines I ground up 10 grams of coffee beans on the four different settings. Below are the results.
- 0.1 setting gave 2 grams of fines, leaving 8 grams
- 3.0 setting gave off 1.8 grams of fines, leaving 8.2 grams
- 6.0 setting gave off 1.8 grams of fines, leaving 8.2 grams
- 9.0 setting gave off 1.8 grams of fines, leaving 8.2 grams.
I used the CUG Coffee Fines Filter as a tester. The problem is that I cannot find the scientific number of the particle holes. On the other hand, some people want the ‘fines’ in their ground coffee since it is also a part of the flavour profile of the coffee. So I guess this is for the people that don’t want the ‘fines’ in their coffee grounds.
Eureka Mignon Brew Pro 55: The verdict.
In my lifetime I have used a lot of grinders. Demoka, Compak, Hario, Minos, Fiorenzato and now the Eureka Mignon Brew Pro 55. What stands out on this grinder is that it is build specifically for pour-over and drip coffee. The grinder looks amazing and will be an accessory to your interior (you can choose several colours when ordering the grinder) rather than a kitchen appliance or something. The angular lines and clean look of the grinder gives off an ‘apple’ design vibe if you get what I mean. The noise the Brew Pro produces during grinding is almost non-existent and the touchscreen works very well. The retention, or absence of it, is just amazing and the consistency is also super good. In short it is way better than any other home-use filter coffee grinder I have encountered so far. There are two minor downsides to the Eureka Mignon Brew Pro that I want to point out. First is the fact that the mucilage flakes stick to the inside of the container. Second is that the container ‘rests’ against the grinder and is easily tipped over. But when you take these ‘downsides’ and compare them to the pro’s, its hardly worth mentioning.
In short: if you are looking for a grinder that’s specifically for pour-over and drip coffee, take a look at the Eureka Mignon Brew Pro for sure! You will not regret it at all!
PS: The price of the grinder is something I can’t say a lot about. In The Netherlands the standard edition is around 470,- euro, in the United States I have seen a website that offers it for 679,- dollar. Best to check your local dealer for the exact price. You can also check the website of Eureka here!
