Mahlgut coffee grinder MOLA-e
The idea behind the Mahlgut coffee grinder MOLA-e is simple: The best high-quality materials, reduced design paired with precise functionality and easily operable. A robust stability with minimal dead space rounds out the concept of the crafted single-dose coffee grinder MOLA-e. Exemplary industrial design from the Ruhr Valley and Made in Germany quality.
MOLA-e is 32 cm altogether in height. The nearly 28 cm wide ground plate, like the cover, is made from German oak, and is solid as a rock. Even light beans cannot shake the otherwise entirely stainless steel fabricated coffee grinder with its 11 kg.
The adjustment of the grinder setting is very easy: release lever, rotate cylinder and set the grinder coarser or finer. Nothing more is necessary. The new grinder setting will take effect immediately with the next portion. The perfect grind setting is quickly found and easily repeatable every time due to the easy-to-read scale and the thin rotation mechanism.
Going without a hopper is typical for a single-dose coffee grinder like the MOLA-e. An opening for easy pour in of portioned coffee beans is sufficient. This is designed this way so that an additional seal is not necessary. Furthermore, the dual mounted shaft for the grinder behind the opening, along with the sealed ball bearings, are protected by a control. Should a finger get in there, nothing happens and no one is injured. Of course, that is also why no beans and coffee grounds come in contact with the shaft or the ball bearings.
When the grind setting is configured and the correct portion of coffee beans poured in, then the grinding process can be started. Just push the button and wait a moment until all the beans are neatly and quietly ground up. MOLA-e rotates at a gentle 100 rotations per minute, just as fast as a comparable hand grinder. As a result, there is absolutely no overheating with the mill charge. Despite the low rotation speed, the Japanese-made motor can withstand a temporary load of up to 20 N.m therefore, light roasts are also no problem. The transmission of the motor to the shaft occurs over low maintenance and quiet metal gear wheels which convey the power optimally. As soon as the stainless steel button is pushed again, the grinder stops immediately.
The MOLA-e, with its full discharge funnel, ensures that the clump-free coffee grounds are not strewn in all directions, but land where they are supposed to: either in the filter holder or in the optional Blind Tumblr.
Of course the filter holder can be adjusted in height without a problem. Even the filter holder grip pads are height adjustable. Attention: New Portafilterholder. See video at the bottom of the page.
MOLA-e draws its power either over the supplied power supply unit or over an optional Lithium-Polymer battery which disappears completely in the left pedestal and is not visible. With this, the coffee grounds can be flexibly positioned without there having to be a plug in the area. With a fully charged Lipo battery, a good 5-6 kg of coffee can be ground over a time frame of a couple of months.
The heart of the MOLA-e is a reliable, 68 mm conical burr set made of steel that we receive directly from Italy. After loosening just three screws, the entire grinding mechanism can be removed for cleaning. The firm, PlascoTEC, through an optional DLC coating, will make the grinder, among other things, considerable harder and wear-resistant with a lower coefficient of friction.

Q: What about Light Roast Beans? Is that a problem for MOLA-e?
A: Of course not, take a look at the following Video:
Q:How to clean MOLA-e?
A: The best way is to loosen 3 screws and to clean MOLA-e with a cloth or a brush. Please take a look at the following Photos.
After cleaning, simply reassemble in the reverse order, recommending that you screw in the grinder adjuster until it stops.
Q: In addition to the power supply unit, the MOLA-e can also be operated with a battery. What options are there and how do you connect them?
A: That’s correct. Here is some more detailed information about the power supply.
If you do not want to use a power supply, for example because there is only limited space available on the coffee counter, you can use an equivalent alternative: a LiPo battery. A LiPo battery with 4s 5000mAh 14.8V and an XT90 plug would be ideal. These batteries are extremely powerful. They fit effortlessly into the left column of the MOLA-e, as long as they are not in a hard case.
A charged LiPo battery can grind several kilograms of coffee before needing to be recharged. In a regular, private household, charging would therefore only be necessary every few weeks or months. However, LiPo batteries also have disadvantages. Proper handling is required to ensure the battery’s longevity. If the batteries are deeply discharged, for example, this can lead to a defect. By the additional use of a so-called LiPo-guard, this problem can be avoided. It should also be borne in mind that the batteries have no built-in circuit breakers.
If the buzzer sounds (warning: the noise is very loud at about 95 dB) or the diode flashes, the battery should be charged to prevent damage. Use of LiPo batteries is by no means comparable to the use of commercially available batteries and should not be underestimated. If you are unsure, you should use the included power supply or choose the third possible variant: 26650 batteries.
These batteries are used for e-cigarettes, for example. They are also very powerful and inexpensive. They are offered with protective circuitry. However, this is not necessary with our method. This is because the connection of four individual 26650 batteries in series requires the use of a separate protective circuit. A Battery Caddy is required for this. The batteries have sufficient space and are not restricted in their function. We designed the Battery Caddy ourselves and make it available here free of charge as a file for 3D printing along with assembly instructions: MOLA-e 26650 Battery-Caddy
As soon as the batteries have reached a certain discharge state, the protective circuit switches off automatically and the mill stops rotating. In this case, the batteries are exchanged for fully charged batteries or charged in the caddy with the help of a special and very affordable power supply unit. The power supply is also necessary to activate the protective circuit.
There are also very good separate chargers for 26650 batteries to charge them outside of the MOLA-e.
If you do not have the option of printing a Battery Caddy yourself or do not dare to solder it, please do not hesitate to contact us. The 26650 rechargeable batteries last just as long per charge as the LiPo batteries and are a great alternative to the mains adapter.
Q: Is there a wiper available for the funnel on the MOLA-e to sweep out the coffee grounds?
A: Because there was such high demand, we also designed a wiper. This is included and can be easily removed again if you don’t want to use it. We have also released the 3D print file on the web. So anyone who needs a spare part, you can print it out themselves: MOLA-e Wiper
