The portafilter slides into the fork, a short beep, you tap the display once – and as you reach for your cup, the espresso grounds fall gram by gram into the basket. No stopwatch, no re-weighing, no catching drips from the dispensing chute. The grinder knows when to stop.\u003c\/p\u003e\n\n\n\u003ch3\u003eGrinding by Weight – The Small Revolution in Grinder Design\u003c\/h3\u003e\n\n\n\u003cp\u003eMost grinders grind by time. Five seconds, six seconds, maybe seven at some point – depending on bean moisture, hopper fill level, and daily form. The Eureka Mignon Libra grinds by weight. A precision scale is integrated into the portafilter holder, automatically taring your empty portafilter and measuring in real-time how much espresso grounds are falling into it. When you reach the programmed target weight, the grinder stops. You can save two programs – typically a single and a double shot – plus a continuous mode for everything in between. Eureka's patented Instant Grind Weighing Technology is what the manufacturer calls it. In everyday life, it means: forget about weighing.\u003c\/p\u003e\n\n\n\u003ch3\u003e55 Millimeter Flat Burrs, Hardened Steel, 1350 RPM\u003c\/h3\u003e\n\n\n\u003cp\u003eInside, 55-millimeter flat burrs made of hardened steel are at work, driven by a direct drive with 1350 revolutions per minute and 310 watts. The low speed is no coincidence: it keeps the burrs cooler, preserves delicate aroma compounds, and delivers a more uniform grind than faster designs. Eureka's patented Silent Technology dampens motor noise, ensuring the grinder doesn't wake anyone in the house in the morning. The ACE System reduces static and clumps – the espresso grounds fall loosely and evenly into the portafilter instead of sticking in the chute.\u003c\/p\u003e\n\n\n\u003ch3\u003eStepless Grind Adjustment\u003c\/h3\u003e\n\n\n\u003cp\u003eYou adjust the grind size using the stepless knob system below the motor – Eureka's patented Stepless Micrometric Regulation. No clicks, no steps, you adjust exactly as finely as you need, and multiple rotations give you a wide range from espresso to almost filter. The new Versatile Fork is height-adjustable without tools, so every portafilter – whether 53mm, 54mm, or 58mm – fits perfectly. The included magnetic Dosing Funnel makes filling larger doses from eight grams clean and uncomplicated.\u003c\/p\u003e\n\n\n\u003ch3\u003eWhat Grind-by-Weight Really Changes in Everyday Life\u003c\/h3\u003e\n\n\n\u003cp\u003eWhat a grinder of this class solves for most people: you no longer tare manually. You no longer curse when there's a gram too little or too much in the basket. You repeat your recipe day after day with a consistency that time-based grinders cannot achieve in principle. Espresso is complex, but not rocket science. You get a constant in a world full of variables – bean, humidity, daily form – and your shot remains reproducible from morning to morning. This isn't espresso policing; it's simply peace in your workflow. Our opinion is one of many, but we have seen the Libra with home baristas in our showrooms in Bern and Zurich for years – and it reliably solves the weighing problem for the vast majority.\u003c\/p\u003e\n\n\n\u003ch3\u003eAll Features at a Glance\u003c\/h3\u003e\n\n\n\u003cp\u003eWhat's under the hood: 55-millimeter flat burrs made of hardened steel, direct drive with 1350 revolutions per minute and 310 watts, Eureka's patented Instant Grind Weighing Technology with a precision scale in the portafilter holder, stepless grind adjustment with multiple rotations, touchscreen display for two programmable doses plus continuous mode, height-adjustable Versatile Fork without tools, anti-vibration system for stable positioning even when bumping the portafilter, the ACE system against static and clumps, Silent Technology for noise reduction, 300-gram bean hopper as standard (optional 510 grams), and a magnetic Dosing Funnel for clean filling of larger doses.

If you are currently working with a grinder without a scale and get tangled between a tare scale and a wiping cloth when weighing, the Libra will save you noticeable time.

The Libra automatically recognizes the inserted portafilter, tares itself, and stops when the target dose is reached. In practice, we experience the accuracy as significantly more precise than any time-based dosing – because bean moisture, grind drift, and hopper fill level no longer affect the final weight.\u003c\/p\u003e\n\n\n\u003ch4\u003e\u003cstrong\u003eIs the Libra a single-dose grinder?\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eNo. The Libra has a 300-gram bean hopper (optional 510 grams) and is designed as an on-demand grinder with a hopper. Those looking for single-dose in the sense of \"filling one dose of beans per shot at the top\" are better served with the \u003ca href=\"\/en\/collections\/option-o\"\u003eOption-O Lagom series\u003c\/a\u003e or other single-dose models.

This means the Libra fits all typical home espresso machines, from smaller Lelit and Profitec models to La Marzocco Linea Mini and Mini R.

In a quiet kitchen at seven in the morning, the noise remains at a pleasant level. The manufacturer does not officially publish a specific dB value, so we consciously refrain from using numbers that we have not measured ourselves.\u003c\/p\u003e\n\n\n\u003ch4\u003e\u003cstrong\u003eCan I see the Libra live before buying?\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eYes.

However, an external scale under the cup for weighing the final espresso weight in a 1:2 or 1:2.5 ratio still makes sense, as it controls the extraction itself. If you already do pour-over or Aeropress, you'll have a scale within reach anyway.
