Mahlkönig · Flat burrE80S
An 80mm flat-steel commercial espresso grinder built for high-volume cafes that need speed above almost everything else. It is not a home-counter grinder, it is a bar workhorse, and it has since been succeeded by the E80T Grind-by-Sync.
The short version
This is a grinder for a bar doing 250-400+ doses a day, not a kitchen counter, and you buy it for grind speed and thermal stability under sustained load, not for tinkering.
Accept the size, the noise floor, and the price, and it will out-grind almost anything smaller without flinching.
Why people buy it
- Genuinely the fastest premium grinder in its class, an 18g dose in roughly 3 seconds
- 80mm burrs plus active cooling keep grind temperature and particle consistency stable through a rush
Why they don’t
- Large, heavy commercial footprint that makes no sense outside a cafe or a very serious home setup
The full tally
- Genuinely the fastest premium grinder in its class, an 18g dose in roughly 3 seconds
- 80mm burrs plus active cooling keep grind temperature and particle consistency stable through a rush
- Disc Distance Detection gives a real, repeatable numeric fineness reference instead of guesswork on a dial
- Illuminated, adjustable spout and simple interface reduce training time behind a busy bar
- Large, heavy commercial footprint that makes no sense outside a cafe or a very serious home setup
- Discontinued and replaced by the E80T Grind-by-Sync, so parts and support are shifting to the newer line
- Steel burrs run louder and transfer more heat than ceramic alternatives, and pricing sits well into commercial territory
What the community knows
Years of owner threads, distilled — a niche favourite.
German flat-burr engineering respected for consistency and longevity, but the E80S sits quietly outside English-language forum dominance — serious espresso tool hampered by smaller retailer footprint, regional availability, and lower YouTube/Reddit visibility versus Niche Zero…

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Cafes wanting cloud connectivity and Mahlkönig's newest workflow tech move up to the E80T/E80W Grind-by-Sync line, which the manufacturer positions as the direct successor. Shops that find the E80S oversized for their volume typically step back down to the 65mm E65S instead.

Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. A balanced burr set: rotate origins freely — it will keep up.

Common questions
Is the Mahlkönig E80S still available new?
No. Mahlkönig lists the E80S GbW as no longer available and retailers note the line has been discontinued and replaced by the E80T Grind-by-Sync, though some dealers still sell remaining stock or open-box units.
How fast does the E80S grind an espresso dose?
Reviewers consistently report an 18g dose in around 3 to 3.5 seconds, versus roughly 4 to 4.5 seconds on Mahlkönig's smaller 65mm E65S.
What is Disc Distance Detection (DDD)?
It is Mahlkönig's sensor system that measures the actual physical distance between the burrs and displays it, giving a precise, repeatable fineness reference rather than an arbitrary dial position.
Worth comparing
Mahlkönig
EK43S
The shop-counter version of coffee's most influential bulk grinder: same 98mm flat burrs and 1300W motor as the full EK43, just shorter so it fits under a cabinet. Built for cafes grinding retail bags and pour-over by the pound, and adopted by plenty of home fanatics who don't mind the footprint.
CA$3,390–5,350 · US$3,899–5,350
Ditting
804 Lab Sweet
A Swiss single-dose lab/shop grinder built around 80mm cast-steel burrs tuned for roundness over sharpness — the burr set that put the word sweet into grinder marketing. Discontinued and replaced by the 807 Lab Sweet, but still floating around used and in cupping labs.
