As if they needed to further secure their reputation as the King of Grinders, Mahlkonig is back and at it again with their newest espresso grinder: introducing the Peak. Specially designed to provide exceptional shots all day long, with big flat burrs to help accentuate sweetness and provide better particle uniformity, the Peak is the newest innovation on the famous K30 platform and footprint. With the rise in popularity of the EK43 as a shop grinder, and notably as an espresso grinder, Mahlkonig sought to replicate the same performance benefits in a smaller platform. And so they have, with the Peak's cast steel burrs, which are big enough to handle a lower RPM and produce a consistent, fluffy grind shot after shot. Other new features include an advanced double cooling system, helping to keep your shots dialed in even when the heat is on and the line is long. A new interface also graces the Peak, featuring a multicolored OLED screen, programmable timed doses, internal temp readout, and adjustable portafilter and spout lighting. Dose times are accurate to 0.01 s, and the familiar stepless grind adjustment - now with more precise grind range markings - makes dialing in exceptionally easy.

If your shop demands exceptional quality for every shot, the Peak is the answer to your call. Those big burrs help to accentuate sweetness and increase extraction, making it ideal for working lighter single origin coffees. Its timed dosing functions are interruptable, meaning you can dispense part of your dose, sweep and level, then pick up where you left off to finish off the timer. The Mahlkonig Peak comes standard with a 3.3 lb hopper, and is compatible with the smaller 1 lb short hopper (select from the Add On menu above). This grinder comes standard as 115 V single-phase, alternate voltage options are available from Mahlkonig upon request.

A whole different game

If you're contemplating upgrading your grinder, my best advice is that yes, you should. I've installed the PEAK and I'm just stunned. It's fast. It's quiet. It's able to handle the grinding process with absolute confidence. Maybe it's a placebo, but sure thing, the coffee tastes better too.

PEAK Performance from Mahlkonig

I am coming to the Mahlkonig PEAK from a Mazzer Mini E and I have to say it’s like having an entirely new espresso machine. This machine has truly taught me the importance of the grinder in espresso. The cup quality of espresso ground with the PEAK is markedly improved with smoother mouth feel, better clarity, and more transparent flavors. Distributing and tamping the same way I’m seeing better shot color, more even extraction, and more even flow rate throughout the shot. I tend toward light to medium single-origins and blends for espresso and the flavors that the PEAK can pull forward in the cup are fantastic. Grind consistency with the PEAK is fantastic. This grinder is also extremely fast (almost twice the grind rate of the Mini E). It does retain some grinds but nothing crazy. The user interface is also very intuitive and easier to precisely adjust grind times than the potentiometers on the K30. All in all I highly recommend this grinder. If you’re on the fence between the K30 or the PEAK I highly recommend spending the extra and opting for the PEAK.

I can't say enough great things about this grinder. I love the design, the large hopper, the customizable dosing control which is incredibly accurate. I love seeing the internal temperature within the machine as it allows me to adjust the grind to compensate. I'm seeing better color, crema, and most importantly, more flavorful espresso in my opinion.
