Mahlkonig, the official espresso grinder for the World Barista Championship, is famous for designing exceptional grinders that are envied by baristas around the world; the K30 Vario is no exception. The K30 is recognized for its superior features such as grinding on demand, programmable dosing, easy infinite grind adjustment and speed (able to produce a single shot in under 2 seconds). This grinder’s speed and high-capacity ability makes it a popular commercial machine, but prosumers who are devoted to only the most consistent grind will find this to be an extraordinary upgrade.


Dialing in the dose could not be easier than with the K30’s LCD screen with push-button controls. The user can simply depress the single and double shot buttons simultaneously to access the menu. By turning the center knobs, the user can customize the dose time from 0.1 to 10 seconds adjustable to tenths of a second. This unit also has a resettable shot counter that can be used to keep track of the shots delivered on a daily basis as well as a continuous shot counter which can be used to monitor for maintenance needs over the life of the machine.


The K30 produces fresh, precise, consistently-textured grinds through its grinding on demand system with electronic dosing. This grinder is a speed demon and can deliver a single dose at an impressive time of less than 2 seconds! The grind on demand feature also ensures minimal wasting of beans unlike comparable doser models. To active the release of the pre-programmed dose, the user must insert the portafilter into the adjustable holder and hold continuously to drop the dose directly into the basket. An extremely useful feature on this unit is the ability to interrupt and restart the release of the grounds, meaning if the user intentionally or unintentionally lets up pressure on the portafilter, the grinder will stop and automatically save the left-over time. If the user wishes to resume, he/she has only to reinsert the portafilter to complete. To cancel the rest of the dose, the user simply has to depress the single dose button to reset the time.


This machine was designed to make it remarkably easy to infinitely adjust the consistency of the grinds. To adjust grind size, loosen the locking knob located on the top of the grinder unit in front of the bean hopper, from there you can glide the adjustment lever (located beneath the hopper) back and forth to the desired number. Simply tighten the locking knob to secure the location of the lever.


This grinder is equipped with 65 mm flat, steel grinding burrs. An added bonus on the K30 is its exceptionally quiet operation.


The K30 comes equipped with a high capacity 3.3 lb. hopper, the unit is adaptable to other sizes of hoppers at the user’s preference. The hopper contains a sliding “trap door” to allow the user to remove the bean hopper while its full.


Mahlkonig has designed this unit to be extremely easy to disassemble for cleaning and maintenance. Removing the bean hopper, loosening the locking knob, and unscrewing a single screw located on the side of the machine is all it takes to access the inside of the machine. For quick clean-up on a day-to-day basis, there is a removable tray located under the portafilter holder to catch grounds.

    Posted by yves H. on 10th Nov 2015

    I have been using a k3 touch for 6 years and before that a gaggia bur grinder.... Joe was amazing, not only did he deliver a great price but was very knowledgeable in the grinders i was considering. I settled for the k30 and boy is this an amazing grinder ! If i could change one thing it would be to go back in time,and buy a k30 10years ago :) ! It is definitely worth the extra $$$ . 5 days after i placed my order (@10PM) with espressooutlet this baby was on my counter in perfect condition freshly built and tested in Germany ( only 4 shots were pulled for testing) Thank you espressooutlet team ! Thank you Joe Thank you MAHLKONIG !
