Several reasons push me to prefer manual mills to electric mills. They are less noisy, have precision mechanical side that I like, waste less coffee (with less retention). At the time I sought to acquire a coffee grinder, I started listing all the premiums manual coffee grinders on the market. This is the purpose of this article.Continue reading List of premium hand coffee grinders
Recently passionate about the world of coffee, I decided to take my first steps with a manual espresso machine. I automatically excluded any automatic machine because, precisely, it does everything alone and that my only participation in the ritual of coffee preparation is to press a button.
Limited by my budget and after many readings, I compared, weighed and filtered the information to extract a Lelit 41 TEM PID.
According to the description, it seems to correspond to my wishes. What is it really?Continue reading Review and test : Lelit 41 TEM PID
Do you like coffee and you’re in a hurry in the morning? Do you have people at home or you do not want to waste time grinding coffee by hand? So like me, you probably thought about acquiring an electric coffee grinder.
Like hand coffee grinders, there are many models, all prices and different qualities. Some of the electric coffee grinders will have applications for espresso coffee, others for coffee filters. I was looking for a discreet, pretty coffee grinder, with low coffee retention at an affordable price. The coffee grinder I was looking for must marry well with my machines: a La Pavoni and a Lelit 41TEM.
After investigation, a name often appeared: Eureka Mignon.Continue reading Eureka Mignon review
Spreading the coffee in the portafilter is a step to take just before compacting the grind. Incorrectly done, this step can be the cause of bad extractions of your coffees. When you have more coffee on one side of the basket and you cup directly, it creates less dense areas, which will facilitate the passage of water.
Thus, a bad distribution of the coffee grounds before packing them contributes to an ignoble extraction of the nectar. To remedy this problem, there are some small tips. Some of them are little used in the professional world because they take time. Baristas will therefore be more likely to use accessories dedicated to this task.
In any case, it is essential to have the portafilter basket cleaned and dry before adding the grind. This in particular prevents the coffee sticks and adheres to the basket.
This is a method often used by people who fill the basket of the portafilter to the brim. With the finger, spread the coffee without packing it and expel the rest. I’m not a fan of this method, because I think we’re wasting coffee by applying it.
Tap the portafilter
Another method that does not require an accessory is to tap the portafilter on the worktop to break the mounted grounds. Then with your hand you tap on its sides (of the portafilter) to try to adjust the level. This method is the one I used at the beginning, it requires experience and is probably the longest and least effective.
One of the risks of this approach is to put coffee everywhere.
Weiss distribution technique (WDT)
The use of a wooden toothpick or stalk to break the mounted grounds and spread the coffee grind into the basket is often coupled with a funnel. The funnel makes it possible to avoid getting out of the basket coffee by mixing with the toothpick. A funnel can be made by cutting the top of a plastic bottle or the bottom of a yoghurt pot at the right size. Below is a video to explain the process.
Coffee distributors are accessories created specifically to evenly spread the grounds in the basket. They are generally sold between 15 $ and 60 $ but can reach extremes as well as tampers (for example, the luxurious O.C.D. brand sells its distributors at 180 $).
You have to buy a coffee distributor that matches the diameter of your portafilter. Nevertheless, it is a rare accessory for certain sizes. For example, there are a lot of 58mm distributors, but the 57mm is much harder to find (and expensive).
For La Pavoni machines, as I explained for the tamper, I recommend a diameter of 51.5 mm for the coffee distributor. This extra half millimeter prevents coffee from remaining on the edges of the basket. A distributor of such a diameter is rare, I acquired mine for 40 € at BPlus, a company that I had already presented during my test of the coffee grinder Apollo. If you want you an purchase a low expensive 51 mm coffee distributor here.
It’s easy to use a coffee distributor. There are blades under the dispenser which turning will spread the coffee well in the basket. It is necessary to adjust the height of the dispenser (by screwing or unscrewing it, the rim of the dispenser abuts on the portafilter) so as not to pack the coffee. After evenly distributing the coffee, it remains to pack it with your tamper.
My impressions about the usefulness and the interest of such a tool are very positive. The simplicity, the speed of execution and the regularity of the result justify in my opinion its acquisition. I recommend however to choose a heavy accessory (about 450 to 550 g).
By applying one or other of these tips, the water will cross evenly the cake of coffee which will optimize your extractions.
Before buying me a real espresso machine, I had a Nespresso machine. And quickly I became aware of the ecological problem of the pods, but also of their significant costs. I ended up interested in rechargeable pods for these two reasons: no longer use aluminum/plastic unnecessarily and reduce my coffee budget. Today I have the necessary hindsight to be able to share with you my opinion concerning the rechargeable Nespresso pods.
The different types of reusable pods
As you know, grinding your coffee is essential for making a good espresso. I started with a Porlex that I later replaced with the Kinu M47 (which I did the review here). Then I decided to replace Kinu M47 with the latest high quality manual coffee grinder: the “Apollo coffee grinder” (manufactured by BPlus, with the appreciation and permission of La Pavoni). Why ? because the coffee grinder Apollo solves some problems that displeased me, after a longue use, with the Kinu M47.
Let’s see the technical characteristics of the Apollo mill
Detail of the conical grinding burrs of the Apollo coffee grinder (48 mm, Italmill brand with Nanotech Coating)
It is made entirely of metal: the body of the mill is in CNC anodized Aluminum, everything inside is stainless steel, the only rubber element is a non-slip placed under the base. The 48 mm conical burrs are manufactured by the italian Italmill (Nanotech Coating).
Burrs are standard stock by Italmill. It will be easy to replace if needed and are guaranteed for 100k shots.
The mill is available in three colors: gold champagne, silver and matt black. It has a total weight of 1030g and grinds up to 25g of coffee beans.
According to my tests, I grind 13g of coffee in 40 cranks. That is to say that I put between 15 and 20 seconds to grind the coffee necessary for an espresso.
For a coffee grinder of this category, it has a rather attractive price : 222 €. It was delivered to me in a week and I did not have any customs fees.
Design is important for me. Expensive products that, in addition to grinding the coffee, must give a certain pleasure to look at and using them.
Apollo : retro et modern at time
The Apollo coffee grinder is available in three colors: matt black, gray and gold.
It really looks like the columns of the “Basilica Santissima Annunziata del Vastato”, a monument in the style “Mannerism” that is in Italy. This design seems to honor the Italian origins of the burrs brand. In addition, this shape greatly improves the grip of the coffee grinder during use.
The care of
Since the body of the mill is cylindrical, when grinding coffee, it must be able to hold it should prevent turning on itself.
Almost all the coffee grinders on the market are simple smooth rolls. This is binding: you have to squeeze very hard to prevent them from slipping. I had the expense with my first manual mill: the Porlex.
For instance, the Kinu M47 has been designed with a small wedge for the thumb to avoid the rotation of the mill. After several months of use I can say that this approach is not optimal because it requires always the same finger (thumb) to hold it firmly to prevent it slips. To be really effective, it would be necessary to be able to block the mill with all the fingers.
The “thumb wedge” present on the Kinu M47. After 7 months of use at 3 coffees a day, I have the impression that the thumb rest is starting to come off. There is no play but I’m starting to see a small gap (visible in the photo)
Apollo coffee grinder body. Slightly larger diameter than the Kinu M47, it is easier to handle and maintain.
For the Apollo coffee grinder, with its “honeycomb” shape (which is an integral part of the design), the palm of the hand and the fingers adhere perfectly to the mill. It is not necessary to squeeze very hard, which makes it more pleasant to use.
By its shape I think we better hold the handle of the Apollo than the Kinu M47. As you can see in the photos, it is bigger and rounder. When I use a coffee grinder, I always place the palm of my hand on the top of the handle. The crank Kinu is a little narrower and does not have the roundness of the palm of the hand when it is tightened.
The Kinu handle is not unpleasant, but it is less comfortable than the Apollo coffee grinder.
Other generalities of design
Exist two categories of manual coffee grinders. It’s distinguished by the number of steps necessary to prepare the grinder:
- The mills you need:
- open a lid
- pour the coffee inside
- replace the lid
- look for the crank that we often lose (believe it, there is some experience with my Porlex mill)
- place the crank
- grind the coffee
- The mills you need:
- pour the coffee inside and grind the coffee
To my knowledge, there are only two mills that meet the second category: the kinu M47 and the Apollo.
In my opinion, there is one detail that has been better thought of with the Apollo coffee grinder. It has an angle of attack of the funnel which is more pronounced compared to that of Kinu M47. During daily use, this detail is not anecdotal and is important because, it allows you to pour the coffee at once without grains bouncing on the edges (of the funnel) and end up on the ground. In addition, the opening of the cylinder is a little more important at the Apollo mill reducing the chances of loss of coffee.
Setting the fineness of the grind
The setting of the grind of the Apollo and Kinu M47 is not stepless but is done click by click. Like many grinders that work by this mechanism, it is very very accurate (see below for more details).
Although visually similar, the mechanisms of Kinu M47 and Apollo are totally different.
On the Apollo coffee grinder it is possible to turn the adjustment wheel without having to loosen the screw that holds the crank (of course, the adjustment knob does not jump when using the grinder). This is not possible with the Kinu M47: you must loosen the screw first (which holds the crank) and then adjust the coffee grinder coarseness.
More, on the Apollo, it is not necessary to tighten very much the screw that holds the set. The setting will never jump.
By cons with the Kinu M47, I often had the bad surprise to see my setting jump one or two notches when using it.

The container fixing system
The container of the Apollo coffee grinder is screwed while that of Kinu M47 is fixed with magnets. Both systems are effective. Personally I have a small preference for the magnetic fastening system even if the screw system may look much stronger over time.

You will notice in passing that the base of the Apollo coffee grinder is wider than the Kinu M47. This accentuates its foundation.
Disassemble the Apollo
The Apollo mill has a great advantage over its competitor: it can be disassembled entirely and reassembled without losing the settings. The complete cleaning will be all the easier.
Although complete disassembly of Kinu M47 is possible, it is strongly discouraged.
As you can see, you have to go with hammers, at the risk of damaging the coffee grinder. Moreover, when reassembling it is impossible to find the initial setting. Here we go again on several tests to find the good fineness of the grind.
The maker of Kinu M47 says on his site that his grinder can be disassembled without tools in 1 minute. The only problem is that we do not disassemble the entire mill (we remove only the central rod does not allow access to the inside of the coffee grinder for cleaning).
With the Apollo coffee grinder, after removing the central rod, we dismantle all the remaining parts by removing two small screws. We can then remove the second part of the wheel and one of the two ball bearings. As a result, it is very easy to clean the interior of the mill and reassemble it, without loss of adjustment.
Ball bearing detail. It is very large and locks into the cylinder by pushing it in using a hydraulic press or by hitting it with a hammer.

The cleaning of the coffee grinder
With the Apollo coffee grinder, after removing the central rod, we disassemble the rest by removing two small screws. We can then remove the second part of the grinding wheel as well as one of the two ball bearings. As a result, it is very easy to clean the inside of the grinder and then reassemble it, without losing adjustment.
As you can see in the photos, it is much easier to clean the interior of the Apollo grinder because it is removable.
Time spent grinding
This is a recurring question for anyone looking to buy a manual coffee grinder: “How long will I spend grinding coffee?” – “I want it to be fast.”
This is a recurring question for anyone looking to buy a manual coffee grinder: “How long will I spend grinding coffee?” – “I want it to be fast.”
To grind 13 grams of coffee with the Apollo coffee grinder, I do about 40 crank turns. That is to say that I put 15 to 20 seconds to grind the coffee (18 seconds on average after being timed 3 times). Note that the setting is a fine molding compatible with an espresso machine.
In the demonstration video of the Apollo coffee grinder, the operator takes about 25 seconds to grind 15 grams of coffee. As I do not keep the mill on the table when I grind by rotating both the coffee grinder body and the crank, I’m a little faster.
The retention of coffee
The retention of coffee is extremely low on manual coffee grinders (compared to electric coffee grinders that can sometimes hold several grams of coffee). Generally I put one or two drops of water in the coffee before grinding it to neutralize the static electricity responsible for the retention.
I observed that coffee tends to stick a little more in the container of Kinu M47. This forces me to kick on the side of the containers to loosen the rest of the coffee. I have the Apollo for less time but I sincerely feel that it is less the case.

Quality of the grind
In my opinion, the Apollo and the Kinu M47 are quite equivalent in terms of the quality of the grind. They both make excellent espresso (and even use a bottomless filter holder).
The Apollo is a very good coffee grinder. It is beautiful, very functional, with a very good grip, the ability to disassemble fully, easily, finding its settings. It grinds coffee quickly. The defects that I have seen with the Kinu M47, are largely corrected with the Apollo.
In addition it costs less: 222 € against vs 329 € for the Kinu M47. There is therefore a difference of just over 100 € between the two products which is not negligible.
Controlling and understanding the water pressure in your coffee machine is important in order to successfully extract it. This parameter is completely controlled on automatic machines while it is less on a manual machine such as the Pavoni. Some knowledge can help to better understand and better control the water pressure when using the Pavoni machines. In my article, I will especially talk about the pressure exerted on the piston when you press the lever.Continue reading Measure and understand the pressure on a Pavoni
Making a good espresso coffee is a real science. And the latter is a real pleasure. Every coffee we make is slightly different and we try to understand the small detail that influenced his coffee, why we found it better. We test different settings of mills, different quantities of coffee, a more or less long prebrewing…
