The distant future, a one in which robots clean your house and make your breakfast, is getting closer every day with the Mahlkonig K30 Vario Grinder. Not only can this grinder give you a single quality shot of espresso in two seconds, it can do it with professional consistency that other less evolved grinders can only aspire to. This grinder will fulfill every coffee scientist's dream, with intuitive programming, easy adjustments, electronic shot counters...the list goes on.

Features and Functionality

  • High Capacity: The Mahlkonig K30 Vario has a huge bean hopper (3.3 pounds!!), and is one of the fastest grinders we have ever used, able to grind a single shot quantity of espresso beans in under two seconds.
  • Technologically Advanced: Programming this grinder takes another variable out of the picture when brewing espresso, making it even easier to achieve the consistently perfect shot once you get the K30 dialed in for your machine.
  • Intuitive:This grinder might be a robot from the future, but it still focuses on ease of use. With a press of the your portafilter against the power switch, this grinder will produce any quantity you need.
  • Precision, Precision, Precision: Don't sit there and worry about how consistent the grinds will be that come out of this machine, it can handle most settings with ease, which won't leave you guessing if your grind consistency is an issue.
  • Large Hopper: Definitely big enough that you won't need to be filling beans every day. However we do recommend keeping your whole beans stored air tight, or as close to air tight as possible, to ensure maximum freshness.
  • Professional - The K30 Vario is capable of any espresso grind setting you could ever dream of, with nothing short of consistent, professional grinds falling into your portafilter basket
  • From The Future - This grinder is as much of a personal computer as it is an espresso grinder, with programming, an illuminated display and digital timers all included features
  • Precise - This grinder takes a lot of the variables out of grinding espresso, both with quantity, texture and quality of grind
  • Too Much Machine? - This is a commercial quality grinder with superior grind quality and output. Before investing for home use make sure these features are worth the price tag.
  • Heavy - The K30 Vario is quite a bit heavier than even some small espresso machines, making it harder to easily move around if need be

I have a question about the MahlKonig K30 Vario grinder. The manual mentions a Prefuse 16A slow. Is this a machine that can be plugged into a 20 amp USA outlet or are main breaker box modifications required?
A shopper on Apr 9, 2016
Best Answer: 20 A breaker will carry a 16A load, but the fuse will blow first, though very unlikely to happen unless motor is completely stalled

What is the best setting for grinding espresso?
Joan S on Aug 4, 2013

One more question.
I have a expobar expresso machine which likes very fine coffee grounds. I also have a french press. Can this machine satisfy both them? and me. Ha Ha
thank you
A shopper on Nov 6, 2014
Best Answer: Unfortunately, it only grinds variations on a theme of espresso. Which is odd, since it's powerful enough to grind rocks. I bought it knowing it was only going to be used for espresso, but I too enjoy french press and since this thing operates so quietly, smoothly, and efficiently I find myself sneering at it while my Capresso's grand-mal seizure grinding routine wakes my neighbors at 5:30 a.m. Would designing in a lever to separate the burrs to a nice course grind be too much too ask, especially since I had to take out a home equity loan to buy it?

What is the difference between the k30 and k30 air?
A shopper on Jan 8, 2016
Best Answer: They're essentially identical except that the K30 Air has a fan to provide additional cooling. Maybe this could be important in a commercial or extremely high use situation. I've been using my "normal" K30 for a year in my home, for everything from a single cup of espresso in the morning to multiple espressos for dinner party guest and have never noticed ANY kind of heat build up. The grinder is a massive heat sink - I think it would take an enormous amount of grinding before ever heating up. How hot can it get when it only takes 3.2 seconds to grind the coffee for an espresso?

In the video, I noticed that the gauge was set close to zero (fine) and yet the coffee came out too fast. If I am interested in expresso coffee only, should I avoid the Mahkonig K30 that focuses on everything from french press, drip to expresso. Is there more choice of fine selections in a Mazzer MIni type A doserless?
A shopper on Aug 6, 2013
Best Answer: I use the Mahlkonig K30 Vario strictly for espresso, paired with the Izzo Alex Duetto 3. The grinder is very fast and eerily quiet at grinding coffee regardless of the setting for how fine or coarse. To give you an idea, grind setting at 0.5, programmed for 3.7 seconds on double, I get roughly 18.5 grams. Grinds are fluffy, uniform without much clumping even when ground much finer than needed to pull a shot with ideal flow rate / extraction parameters. I highly recommend the K30 and can definitely say that you will not be disappointed with its performance, build quality and ease of use.

Is it necessary to turn this machine either on or off before adjusting grind size?
A shopper on Feb 10, 2017
Best Answer: Yep!, We always recommend grinding through coffee if you are adjusting to a finer grind size.

That is a huge discount. Is the machine being discontinued, and if so would service/parts become difficult?
A shopper on Jan 18, 2015
Best Answer: No, the machine is not being discontinued. We're glad to see it at this nice low price too, as we have been happy with it's consistency. However, it can clog if you use an oilier bean, so be sure that you're not grinding too fine if you're using a darker roast, and be sure to do thorough and regular maintenance to clean the burrs! We do not anticipate service or parts becoming hard to come by, as the grinder hasn't been discontinued.

I have just ordered the MahlKonig K30 Vario grinder and will be arriving in a couple of days. I would like to know if I have to run a GRINDZ cleaner or 1 lb of coffee thru the machine to clean it from manufacture oils before I pull my first shot?? If I do run 1 lb of coffee thru it can I do this all at once or is there a max run time?

Great upgradeReview by PJS
I suffered with a Baratza Vario (I had two, one for regular, one for decaf) for about a year. I know this seems very expensive for a grinder but it was the best money I ever spent. An incredibly consistent and predictable grinder. No more splatter all over my Rocket Cellini when using the bottomless portafilter. The K30 just quietly and quickly grinds great coffee. No drama or frustration, which is very important in the morning. Fill the portafilter to about half, give it a little shake, fill it to the top, level and tamp, you are good to go. I think it looks pretty cool too. (Posted on 10/19/2016)
