The Complete Guide to Macap Coffee Grinders
Macap has been building coffee equipment in Italy since 1930 and now supplies more than 70 countries — a track record that shows up in the details rather than the marketing. CommercialEspressoMachines.com carries five Macap models, from the compact MI20 Luxe (from $1,149) up to the grind-by-weight Supra 83 G Series (from $2,149). This guide breaks down burr size, motor output, and dosing technology across the full lineup, so you can size a grinder to your actual daily volume instead of guessing.
Choosing by Daily Volume
The fastest way to narrow down a Macap grinder is to work backwards from drinks per day rather than starting with burr size. Under roughly 75 drinks a day, 58–64mm burrs are enough — that's MI20 Luxe territory. Between 75 and 150 drinks a day, you want 64–75mm, which puts the Supra 68 and its roughly 6 kg/hour output in range. Past 150 drinks a day you're into 75–83mm, where the Supra 83 sits, capable of up to 10 kg/hour and an 18g dose in about 2.7 seconds. As a rough benchmark, a cafe pulling 300 espresso drinks a day grinds around 5 kg of coffee. Undersizing is the expensive mistake here — a grinder run at its ceiling heats up, drifts off calibration, and wears out early.
MI20 Luxe: Home and Light-Commercial Grinding
The MI20 Luxe (from $1,149) runs 58mm flat steel burrs on a 300W motor, outputting 2.0–2.6 g/s, in a compact 7.6" × 12.1" × 17.3" body that fits under standard kitchen cabinets. The "Luxe" designation refers to the Nice Grind Control Dial — a stepless micro-step adjustment system that moves grind size in very fine increments rather than fixed clicks, which matters if you dial in regularly or rotate between different coffees. It's a natural pairing for anything in our Home Espresso Machines collection. The Supra line below is built for genuine commercial duty with a larger 1.5 kg hopper — more grinder than a home bar typically needs, though plenty of enthusiasts run one anyway.
Supra 68 vs. Supra 83: Scaling Up for Commercial Volume
The difference between the Supra 68 (from $1,649) and Supra 83 (from $1,899) comes down to burr diameter and motor, nothing else. The Supra 68 runs 68mm flat burrs on a 550W motor for 3.8–4.5 g/s. The Supra 83 steps up to 83mm burrs and a 750W motor for 5.5–6 g/s. Bigger burrs cut faster and put less heat into each dose, which is what protects grind consistency through a long rush. Touchscreen dosing, the 1.5 kg hopper, and the overall footprint are identical between the two models, so the decision genuinely comes down to throughput rather than features.
G Series: Is Grind-by-Weight Worth the Upgrade?
Both Supra models are also available as Supra 68 G Series (from $1,899) and Supra 83 G Series (from $2,149) — roughly a $250 premium over the standard time-based models. Time-based dosing drifts: as beans age, humidity shifts, and burrs season, an 18g dose can quietly become 17.4g without anyone noticing until the shots start tasting sour. The G Series doses by weight instead, using an integrated scale with Instant Tare (zeroing before every dose) and Smart Dose Recognition, which reads the portafilter by its empty weight and applies the correct recipe automatically. For a bar with multiple baristas or more than one coffee in rotation, this removes a recurring calibration chore — for a single-barista setup with one house blend, the standard time-based Supra may be all you need.
Macap vs. Fiorenzato, Eureka, and Mahlkonig
These brands overlap, but each leads somewhere different. Our Fiorenzato collection is the closest match on burr sizing and tiering, spanning the F64 EVO up through grind-by-weight Sense models. Our Eureka collection built its reputation on the Atom line and Diamond Inside burr coating, and tends to run quieter. Our Mahlkonig collection sits a clear tier up in price, anchored by the 98mm-burr EK43S. Macap's case is commercial-grade dosing technology and genuine Italian build quality at mid-market pricing — past entry-level territory, below Mahlkonig's flagship pricing. Compare all of them directly in our full Coffee Grinders collection.
Burr Life and Maintenance
Macap quotes a working burr life of roughly 400 kg of coffee, with commercial steel burrs generally landing somewhere between 300 and 800 kg depending on the beans and grind setting used. A busy cafe might reach that inside two years; a home MI20 Luxe could run a decade. Go by symptoms rather than the calendar — clumping, drifting grind settings, or espresso that tastes flat no matter how you adjust are the real signals. Routine care is light: brush the chute weekly, clean the burr chamber monthly, do a deeper clean quarterly, and never let water near the burrs. The Supra's tool-free Fast Opening System gets you into the chamber in seconds when it's time to clean.
Power and Warranty
US-market Macap grinders run on standard 110–120V power with ETL/CE safety listing, so no transformer or dedicated circuit is required. Macap's own documentation cites a 24-month warranty from invoice date, excluding wear parts like burrs — specific terms can vary by model and seller, so it's worth confirming details before ordering if warranty coverage factors into your decision. Our team can walk through the specifics for the model you're considering.
Completing Your Setup
A Macap grinder pairs with any machine in our Espresso Machines or Home Espresso Machines collections, since grinder and machine are independent purchases. Round out the setup with an automatic PUQ coffee tamper to keep tamping pressure as consistent as your dose.
