The grinder that defines your ceiling, dialled in right
German engineering, championship lineage, and the EK43 Matt Perger made world-famous
Mahlkoenig is a German grinder maker known as "The King of Grinders." Its EK43 popularised flat-burr espresso grinding; the E80 and X-series cover café and home use.
Every barista will tell you the same thing: the grinder matters more than the machine. Mahlkoenig grinders have earned the title "The King of Grinders," and we've stocked the range since the EK43 became the grinder serious cafés built around. From the EK43 to the E80 Supreme, the home X54 and the single-dose X64 SD, each one earns its place on burr quality alone. Here's how to choose the right one.
What Mahlkoenig actually gets right
Mahlkoenig builds its burrs in-house, and that is the part that matters. The burrs are the heart of the grinder, and Mahlkoenig treats them that way rather than buying them in. The EK43 runs 98mm flat steel burrs; the E80 series runs supersized 80mm special steel discs with Disc Distance Detection and a high-definition display for grind adjustment you can read at a glance.
Scott Rao makes the technical case plainly: commercial espresso grinders are designed for bimodal particle distribution, where coarser particles allow flow and finer particles give the surface area for fast extraction. Sharp burrs and larger functional burr surfaces also disperse heat better, and overheated grounds lose aromatics and clump. The large flat discs across the Mahlkoenig grinders range are built for exactly this.
Where people go wrong is matching the wrong grinder to the wrong workflow. The EK43 and EK OMNIA are all-rounders that handle espresso, filter, and Turkish with a blade swap. The E80S Supreme is a high-volume café espresso grinder. The X-series is home-scaled. We've tested these across café and home benches, and the burr set decides the result far more than the badge does.
Which Mahlkoenig grinder is right for you?
Start with where the grinder will live and how much coffee passes through it daily. That single question rules out most of the range and makes the rest obvious.
Home espresso and all-round
The Mahlkoenig X54 AllRound Home Grinder is the entry point. Its 54mm burrs handle espresso through to filter, and it suits a single-machine kitchen where one grinder does everything. Step up to the E64 WS, with 64mm flat burrs and a wood-trim hopper, when you want espresso-focused consistency and a quieter bench.
For single dosing at home, the Mahlkoenig X64 SD is the pick. Mahlkoenig rates it for zero retention, a fresh dose every time, 64mm steel burrs, stepless micron-level adjustment, and an included bellow for purging. It ships with swappable toppings: a hopper extension for capacity, the bellow for clean purging, and an anti-popcorning lid. Net weight is 4.8kg in a compact 14.3 x 24.9 x 25.3cm footprint, so it earns a place on small benches.
Café and high volume
The E80S Espresso Grinder is built for a busy bar: 80mm special steel burrs, a high-performance motor, near-silent grinding, temperature control, and an 88.3mm high-definition display. The E80W GBS (Grind-by-Sync) and E80S GBW (Grind-by-Weight) variants add dosing automation for sites chasing shot-to-shot accuracy across hundreds of coffees a day.
The EK43 question
The EK43 and EK43S sit in their own category. They run 98mm flat burrs and remain the reference grinder for filter and a generation of cafés that adopted them for espresso. The EK OMNIA is the modern all-round successor, with universal 98mm cast steel burrs and dedicated espresso, Turkish, linseed, and poppy cuts via a burr swap. If you want one grinder that does everything to a high standard, this is it.
What to pair it with
Whatever you choose, keep it clean. Stale grounds in the chamber undo good burrs, so a grinder cleaner and a soft brush belong in the order. Replacement burrs are a maintenance item, not a failure, and we stock them. Browse the full Mahlkoenig coffee grinder range or compare against the wider espresso grinder category before you commit.
In 2012, Australia's Matt Perger won the World Brewers Cup in Vienna with a Hario V60, borrowing a Mahlkoenig EK43 mid-competition. He took it home, used it as an espresso grinder, and over the following years made the EK43 famous across the global specialty coffee industry. Matt is a personal friend of Pedro's, and partly off the back of the relationship he forged with Mahlkoenig, Coffee Parts is now one of Australia's largest EK43 retailers.
A grinder is one part of the chain. To get the most from a Mahlkoenig, pair it with a scale for dose accuracy, distribution tools for an even bed, and a cleaning routine that keeps the burrs honest. We'd suggest a set of coffee scales for repeatable shots, distribution tools for café-grade prep, and a regular degas of stale grounds from the chamber. If the Mahlkoenig is feeding an espresso machine, matched water filtration protects both. Get these dialled in together and the grinder does its best work.
I'll be honest about the EK43: it became a legend partly because of a friend of mine. Matt Perger borrowed one mid-competition in Vienna, won the world title, and brought it home to St Ali. He taught the world to grind on it. We passed on his first parts order back when he was a kid building a machine, and we've laughed about that since. We've been one of Australia's biggest EK43 retailers ever since, and we don't recommend a Mahlkoenig we wouldn't run ourselves.
Frequently Asked Questions
Is the Mahlkoenig EK43 worth it for espresso? +
The EK43 is the grinder that popularised flat-burr espresso grinding worldwide after Matt Perger took one home from the 2012 World Brewers Cup. Its 98mm flat steel burrs deliver the consistent particle distribution espresso rewards, and it doubles as a filter grinder. It's a high-volume reference grinder rather than a compact home unit, so match it to your bench and throughput.
What's the difference between the Mahlkoenig EK43 and EK43S? +
Both run 98mm flat burrs. The EK43S is the shorter-bodied version, designed with espresso workflow in mind, while the standard EK43 is the taller original favoured for filter and high-volume grinding. We stock both, including Turkish-blade variants, and can help you match one to your setup.
Which Mahlkoenig grinder is best for home use? +
The X54 AllRound is the entry home grinder, handling espresso through filter with 54mm burrs. For espresso focus, the E64 WS steps up to 64mm burrs. For single dosing with zero retention, the X64 SD is the pick: 64mm steel burrs, stepless micron adjustment, and a compact 14.3 x 24.9 x 25.3cm footprint.
Does the Mahlkoenig X64 SD have low retention? +
Yes. Mahlkoenig builds the X64 SD as a zero-retention single-dose grinder, so no grounds are left behind and you get a fresh dose every time. It includes a bellow for purging, plus swappable hopper-extension and anti-popcorning toppings. Minimum espresso output is rated around 3 g/s.
Can I buy replacement burrs for my Mahlkoenig? +
Yes. We stock replacement and upgrade burrs, including 80mm Alinox-coated discs for the E80S, 98mm sets for the EK43 and EK43S, and SSP Red Speed 98mm burrs. Burrs are a maintenance item, and we keep them so a refresh or service is straightforward.
Is Coffee Parts an authorised Mahlkoenig retailer in Australia? +
Yes. We're an authorised Mahlkoenig retailer and have stocked the range for years, with Australian stock and parts support. Every grinder is checked before dispatch, and our Sydney service team works on these daily.
What does the Mahlkoenig EK OMNIA grind besides coffee? +
The EK OMNIA is an all-round grinder using universal 98mm cast steel burrs with dedicated cut profiles. Beyond espresso-fine coffee, Mahlkoenig offers Turkish-fine, linseed, and poppy cuts via a burr swap, making it a versatile single grinder for varied grinding tasks.
