Quick Summary 

Mahlkonig K30 Vario Air

 Mahlkonig K30 Vario Air

The Mahlkonig K30 Vario Air was an espresso grinder clearly designed to withstand a high level of demand. Its large burrs and robust motor are capable of grinding up to 4.8 grams of coffee per second, meaning it can produce shots of espresso in approximately two seconds. Best of all, its high-quality fan cooling system allows it go all day long without breaking a sweat.

Key Features 

Flat Burrs 

Within every high-end espresso grinder, you’ll find burrs. Burrs are the sharpened grinding discs that crush your coffee beans as the beans pass through them.

There are two main types of burrs: conical and flat. The Mahlkonig K30 Vario Air has flat burrs. That means it has a pair of flat serrated discs that stack up on top of one another.

Flat burrs have their own benefits that are different from conical burrs. The greatest benefit they offer is an unparalleled consistency, producing coffee particles that are all the same size. Many espresso experts say that coffee produced by flat burr grinders has a decadent and sweet flavor.

Burr shape isn’t the only important quality to mention here, though. The Mahlkonig’s burrs are quite generously sized at 65mm in diameter, giving the grinder a nice speed boost.

Illuminated Display 

Preparing espresso is a task that requires a surprising degree of precision. There are multiple steps that go into every single espresso-based drink, such as grinding beans, brewing, and frothing the milk.

Each of those steps can be subdivided into other steps, and that includes grinding the coffee. Baristas need to be able to carefully monitor what they’re doing at all times to ensure that every drink is up to a quality standard.

The Mahlkonig K30 Vario Air is designed to guarantee baristas can always clearly see what they’re doing with its illuminated display. Its illumination makes it easy to program doses or access settings because it’s crystal-clear.

Fan Cooling 

Do you often have lines of customers at your counter? If so, you’ll need a grinder that can keep up with such demand, and not all grinders are equipped for it.

Fortunately, the Mahlkonig in this review is designed to meet high levels of demand. It has an integrated fan cooling system that controls its internal temperature, protecting it from overheating.

Not only does this protect your grinder from potential damage, but it shields your coffee beans from dangerously high temperatures. No more burnt-tasting cups of coffee here.

Large Capacity Hopper 

The more beans your grinder holds, the longer it can grind for before you need to stop for a refill.

Another quality you’ll need to be concerned about if you have a high volume of espresso orders to fulfill is your grinder’s hopper capacity. The more beans your grinder holds, the longer it can grind for before you need to stop for a refill.

This is one aspect where the Mahlkonig K30 truly shines. Its hopper holds up to 3.3 pounds of beans, which makes it perfect for helping your baristas power through rush hours.

Whether it’s the morning rush for coffee or the post-work bubble, your baristas will be able to work uninterrupted for the longest possible time. Refills will be few and far between.

Shot Counter 

Any experienced business owner knows that you need to have a good grasp on your average expenses. You’d never understand how much supplies you need or how much you’re making in profits if you don’t know how much you’re going through.

That’s why the Mahlkonig’s electronic shot counter is so useful. At any time, you can determine exactly how many shots of espresso have been prepared by checking the grinder’s record. You’ll have a perfectly clear snapshot of your espresso expenses and can adjust your supply or prices accordingly.

Hands-Free Grinding 

Restaurants, cafes, hotels, and other businesses that offer espresso to customers are packed full of daily duties employees need to complete. At any time, there are likely dozens of other jobs your employees could be doing other than simply grinding espresso.

Multitasking is something the Mahlkonig K30 is prepared to help you accomplish. It has a portafilter holder built onto the front of the machine, so your baristas don’t have to hold the portafilter basket in place the entire time while grinding.

Doserless Grinding 

Doserless grinding is oftentimes also called on-demand grinding. The concept is simple: rather than grinding a stock of coffee in advance, you grind single servings as you need them.

This is a concept the Malkonig K30 adheres to. As a result, every single shot of espresso or filter of coffee you prepare is as fresh and aromatic as possible.

Your customers will notice the difference in flavor when their espresso is prepared completely to-order every time.

Programmable Dosing 

If your business has a high volume of espresso orders or high rate of turnover, then you won’t want an espresso grinder that takes forever and a day to train employees on. You’ll want something that’s quick, convenient, and easy to learn.

That’s where the Mahlkonig’s programmable dosing functionality comes into play. Instead of forcing your employees to learn the times for each dose and then carefully time the grinder themselves, you can program the durations for single and double shots in advance.

After the single and double shot doses have been programmed, getting the precise amount you need is as simple as pressing the right button. Aside from being user-friendly, this function also allows baristas to multitask, since they won’t have to meticulously time each shot themselves.

Stepless Grind Adjustment 

We would be remiss if we didn’t mention the Mahlkonig K30’s impressive stepless grind adjustment system. Basically, it means that the fineness options you have to choose from are endless.

To understand why, it’s best to compare a stepless system to a stepped one. A stepped grind adjustment system will give you a dial that clicks into place at specific fineness settings created by the manufacturer. It’s the easier setup, but it’s significantly less flexible, as you’re stuck using only the pre-made fineness settings.

The Mahlkonig K30 will have much more flexibility. You can turn its grind adjustment collar to literally any point on the fineness spectrum.

Comparable Alternatives 

Mahlkonig Peak

 Mahlkonig Peak

If you go online and search for the best Mahlkonig grinders, we can almost guarantee most lists will include the Peak. The Peak is one of Mahlkonig’s most beloved models, built with speed, power, and flexibility in mind.

So, what makes this grinder great? For starters, consider its impressively sized 80mm cast steel grinding burrs. Such large burrs allow it to quickly and effortlessly grind doses of espresso.

Then factor in the Peak’s amazingly precise stepless grind adjustment system. This system gives you absolute control over the texture of the grind, making the adjustment possibilities endless.

Here are some other benefits offered to you by the Mahlkonig Peak:

  • An adjustable spout so you can grind into the middle of any portafilter.
  • Spout illumination that clearly lights up your workspace.
  • Double ventilation to keep your coffee beans cool during grinding.
  • A live temperature readout that helps baristas keep tabs on the grinding conditions.

Ceado E37T

 Ceado E37T

Ceado is another reputable espresso grinder manufacturer with tons of options you can rely on. Their E37 series grinders are excellent, suitable for a wide range of settings. We especially like the E37T, which makes many improvements to the series.

One improvement is the increase in size to the grinding burrs. With burrs that are now 83mm in diameter, you can trust that the grinder will make short work of your coffee beans.

We can’t help but mention the steady lock design, too. After you choose your ideal fineness level, the grinder locks it into place, preventing your settings from gradually shifting over time.

These are some other noteworthy features of the E37T:

  • Three programmable buttons that allow you to save three different doses in advance.
  • An integrated shot counter, so you can keep track of your expenses.
  • A beautiful touchscreen display for user-friendly operation.
  • An extremely powerful 740-watt motor to help the grinder crush beans quickly.

Fiorenzato Evo

 Fiorenzato Evo

The Fiorenzato Evo may not look anything like the Mahlkonig K30, but open up these grinders and you’ll discover they’ve got a few striking similarities.

For one thing, the Evo has generously seized 64mm flat burrs. Just like with the K30, you can demand total consistency from the Evo, thanks to its sturdy burrs.

It also has a large capacity hopper that can hold up to 3.5 pounds of coffee beans. This is one grinder that won’t need frequent breaks, empowering your baristas to grind for as long as they need to.

Here are a few additional benefits provided by the Fiorenzato Evo:

  • Four different color options to make it easier for you to find a version that matches your settings.
  • A precise stepless grind adjustment system.
  • On-demand grinding design that promotes freshness in all your drinks.
  • Attractive design that will look great on any counter.

For that reason, we feel the best applications for this Mahlkonig are in small to large businesses, such as coffee shops, restaurants, and hotels.

Great Grinder!

Wonderful upgrade from my old burr grinder. The options are a little overwhelming, but that is a good thing!

Perfect every time

It is actually kind of eerie after 10 years of using a Silvia to get absolutely consistent coffee that gets all the little nuances of flavor. An amazing machine.

Fantastic Machine

This is a huge step up from my beloved Rancilio Sylvia, which was 20 years old. Excellent Machine- with a very gently learning curve. Highly recommended!

Newbie!

I’m a completely self taught barista who got a wild hair to open a small coffee shop in a location that didn’t have one and this machine did not disappoint!! Minus the manual not being friendly to the inexperienced..- with a little research I was elbow deep in milk!!! I pulled about 80 shots my first day and around that much my second! Fantastic machine, if you can eeek out the money!!!

I love my 270Wi!

Tony was a tremendous help and expertly answered all of my questions. I really appreciate the time that he took with me to compare various models and am very happy with my decision!
The grinder is a solid piece of equipment and is very high quality. It's nice to grind to the gram rather than do a timed grind and then have to weigh.
Since filled hoppers are easily swapped, I ordered a couple of extras and now can have a few varieties on hand.
I really like the contemporary styling. I also notice that when viewing the Baratza from the front, as it currently sits on my counter, that the focus is on the "business end" of the machine, and the dramatic styling becomes more subdued, enhancing the Baratza's look. Thank you, Majesty Coffee!
