Quick Summary

The Mahlkonig E65S GBW was created with the ultimate precision in mind. Its grind by weight system measures out the perfect doses for espresso down to .1 grams to help you be sure you’ll get the exact amount you need for any drink at any time.

Mahlkonig Peak


Mahlkonig PEAK Espresso Grinder


Ask any espresso grinder expert what some of the best Mahlkonig grinders are, and we can almost guarantee the Peak will be on their list. Its robust double ventilation system and reduced motor revolutions are adept at keeping cool even during days of nonstop grinding in a lively coffee shop.

Stepless Grind Adjustment

High-end grinders allow you to choose different fineness settings. This is because different blends require specific fineness levels to accentuate their flavor. 

There are two main ways of dialing in the grind: a stepped or stepless grind adjustment system. In a stepped system, users are restricted to settings built into the grinder by the manufacturer.

A stepless grind adjustment system removes those limitations by essentially providing you with a sliding scale of settings to select. The Mahlkonig E65S GBW and Peak both use a stepless system, which means you can find the ideal texture for just about any blend.

Spout Illumination

Have you ever tried to work in the dark? It’s not easy, and it makes precise operations like making beverages almost impossible.

Your baristas need to see what they’re doing when they make specialty drinks like lattes. That’s why the E65S GBW and the Peak each have spout illumination. 

By providing light around the spout, baristas are able to clearly see what they’re doing at all times, reducing the risk for human error. 

Cooling System

Do you frequently have lines of customers forming at your counter? Then you’ll need a grinder that can withstand the pressure without overheating. 

Either the Mahlkonig E65S GBW or the Peak can stand strong under pressure. Because of their integrated cooling systems, they don’t get too hot even when they’re used continuously. 

In a busy commercial setting when you’ve got back-to-back orders, you can breathe a sigh of relief knowing you can rely on these grinders to protect your beans from burning.

Hands-Free Grinding

If you had to just stand in front of your grinder, holding the portafilter up, every time you needed to use it, you’d be losing time. It might not seem like much, but that time truly does start to add up.

With the hands-free grinding design of the E65S GBW and Peak, this is no longer an issue. Their portafilter holders will keep a firm hold on the portafilter during use, which makes multitasking easy for your baristas. 

On-Demand Grinding

Some grinders, like Baratzas, come with containers that you can grind into. This allows you to make large batches you can use throughout a period of time. 

The drawback, however, is that there’s a potential for waste or the grounds growing stale. This is precisely why, instead of container grinding, these Mahlkonigs use an on-demand grinding system. 

By grinding espresso to order as you need, your customers can rest assured that they’re getting the freshest-tasting drinks time after time. Additionally, you’ll save on waste, because you’ll only be using exactly as much as you need when you need it.

Burr Type

Many commercial-level grinders, including the E65S GBW and Peak, use flat burrs. What does this mean for you?

It means uniformity in the resulting coffee particles. This uniformity results in nutty and decadent flavors that are perfect for sweeter types of coffee.

Adjustable Spout

The Mahlkonig E65S GBW and the Peak each have adjustable spouts. If you use portafilters of different sizes, you’ll love this feature.

Because you can easily adjust the spout, you can grind right into any portafilter, no matter the size. By grinding right into the portafilter, you can promote balanced extraction that leads to a more well-rounded flavor. 

Color Choices

We offer both the E65S GBW and Peak in black or white. This has no influence on the daily use of the grinder, but it does give you the ability to find a color that better fits in your establishment.

If you think that doesn’t matter, consider how your business looks from a customer’s perspective. Appearances really can be important, especially when it comes to making a first impression. For that reason, the ability to choose the color of your grinder could be important.


Hopper Size

Beyond the burrs, the hopper might just be one of the most important features of any grinder. The hopper, which holds the beans, dictates how long you can grind at once before you need to pause and add more coffee beans.

This is critical in businesses with a lot of espresso and coffee orders. The last thing you want to do when you’re in the middle of a rush is stop frequently to refill your grinder – you want your customers served as quickly as possible.

In this regard, the Mahlkonig Peak wins. Its hopper can hold 3.3 pounds of beans, whereas the E65S GBW’s can hold around 2.6 pounds.

Grinding Speed

Just as you might be concerned about having to stop for refills when you’re busy, you’ll also likely be concerned about how fast your grinder can go. When it comes to speed, the E65S GBW is the clear victor.

Put it side by side with the Peak, and you’ll see that it can grind twice as fast. In a single second, the E65S GBW will produce up to 7 grams of espresso, while the Peak will produce around 3.5 grams. 

In other words, you’ll be able to make shots of espresso in half the time it would take the Peak. Your customers will appreciate the reduced wait time.

Burr Size

Similar to hopper size, the size of the burrs in your grinder can also be crucial. Larger burrs often contribute to faster grinding and a greater ability for your grinder to stay cool. That’s because the burrs don’t need to rotate as much in order to grind more.

Out of these two grinders, the Peak actually has larger burrs. Its burrs are 80mm. The E65S GBW’s, on the other hand, are 65mm. 

It’s worth noting, however, that either one of these grinders is still fast enough for commercial settings. 

Mahlkonig E65S GBW Programmability

It takes time to learn to use new appliances, including grinders. There’s timing to consider, as well as learning how to switch out blends or refill the grinder whenever necessary.

This is part of the reason why they can be kind of overwhelming for new baristas, on top of everything else they have to learn. The good news is, the E65S GBW helps make it simpler for your baristas to learn the ropes because you can program up to six different recipes into it.

Grinding the perfect amount for singles, doubles, or other drinks will be as effortless for your baristas as simply picking the right recipe from the straightforward icon menu. Even your newest baristas will have no problems learning the ropes with the E65S GBW.

Mahlkonig Peak Reduced RPMs

If you’ve ever tasted coffee or espresso that was bitter and burnt, it’s quite possibly because the grinder overheated while grinding the beans. This is just a risk you have to face when you have a lot of RPMs in the motor. 

To shield your coffee beans from this risk, the Peak has reduced RPMs. Its idle speed of 900-1,100 will preserve the delicate flavors of your blends, transferring them to your customer’s cup.

So, Which Should You Buy? 

If you still can’t decide which Mahlkonig to buy, it’s time to stop and consider your own unique circumstances. These will shape the requirements you’ll have for your grinder.
