Eureka Oro Single Dose Pro – Single Dose Espresso Grinder with 65mm Burrs
You weigh your beans, pour them in, grind – and what comes out at the bottom is practically everything that went in at the top. Fresh for that one shot, with no leftovers from yesterday.
The Oro Single Dose Pro is Eureka's well-designed single-dose grinder: short paths, very low retention, and a burr set that handles espresso as well as filter. Coffee Coaching Club carries the Eureka range; Eureka has been manufacturing in Florence, Italy, since 1920. Available in Black, Chrome, and White.
Single Dose – Fresh for Every Shot
With single dosing, you weigh out exactly the amount you need and grind it directly. To ensure as little as possible remains in the grinder, Eureka has combined several features: a 15-degree inclined grinding chamber for a short, clear path, an upper blind burr without screw holes, and the Blow-Up system, which uses a puff of air to clear out any last remnants. The ELR system (Extremely Low Retention) is designed for virtually residue-free grinding – ideal if you switch between beans without carrying over yesterday's flavor.
65mm Burrs, Diamond Inside
The 65mm flat burrs are diamond-coated (Diamond Inside) and deliver a consistent grind – around 2 grams per second for espresso, up to about 3.8 grams per second for filter. The direct drive with 320 watts rotates at 1650 revolutions per minute and maintains its speed even under load. Sound insulation on the hopper, chute, and motor keeps grinding noise low, while the ACE system (Anti-Clump & Electrostaticity) reduces clumps and static charge.
Operation and Workflow
The grind size is steplessly and micrometrically adjusted via the large King-Size Dial – with a rotation counter, so you can find every setting again and safely switch between espresso and filter. An Anti-Chaff funnel guides the ground coffee cleanly downwards, the shatterproof 45-gram hopper with Blow-Up and Anti-Popcorn feature keeps the beans in place. The metal dosing cup (80 grams) with a spout delivers the powder directly into the portafilter.

Who it's for
For anyone who grinds fresh for every shot and often switches beans – without remnants affecting the next coffee. Thanks to the Diamond Inside burrs and the rotation counter, it's all-purpose: fine espresso as well as coarser filter coffee. If you prefer a hopper grinder with fixed dosing, you can find alternatives in the Eureka grinder collection.

What goes with it
The Oro Single Dose Pro pairs well with any portafilter machine from our espresso machines. For tamping, a tamper – affordable and precise from the Normcore range, high-quality from the Weber Workshops collection. To weigh single doses, a scale from the Acaia collection. For filter coffee, a hand filter from the Hario collection. Plus fresh beans like Cozy Chocolate, Nutty Delight, or Very Nutty.
Frequently Asked Questions
What does Single Dose mean?
For each serving, you weigh out the exact amount of beans you need and grind them directly – without a supply in the hopper. This keeps the coffee fresh and allows you to switch beans at any time.
How much remains in the grinder?
Very little. The inclined grinding chamber, the upper blind burr, and the Blow-Up system are designed together for virtually residue-free grinding. A puff of air removes any last remnants.
Is it also suitable for filter coffee?
Yes. Thanks to the Diamond Inside burrs and the stepless grind adjustment with a rotation counter, you can set it for fine espresso as well as coarser filter coffee and reliably recall both settings.
Can I see it before buying?
Gladly. You can experience the grinder live in Bern and Zurich Oerlikon. If you'd like to test grinders directly side by side, there's our Espresso Machine and Grinder Comparison for that.
Roastery Tip
Single dosing plays to its strengths when changing beans – a chocolatey espresso in the morning, a fruity filter coffee in the afternoon, without anything mixing. For espresso, use Cozy Chocolate or Nutty Delight, 1:2 as a starting point. If you like maximum body without acidity, try Very Nutty; for a fruity filter experience, Wild Peach. This is our recommendation, one of many.
