Grind size and dose in one appliance
The Melitta Calibra combines a steel conical grinding mechanism, 39 grind settings and an integrated digital scale. Its main attraction is weight-based coffee dosing rather than relying only on grinding time or an approximate cup setting.
This overview is adapted from our existing equipment review, not a hands-on testing report. Specifications and manufacturer recommendations below reflect that source, not independently measured performance. Confirm the current model and package before buying.

Why consider the Calibra?
Grind size and coffee dose both affect a brewing recipe. The Calibra lets you select a grind setting and dose by weight from the grinder itself, which can simplify a repeatable home-brewing routine.
It sits between simpler adjustable grinders and specialist equipment. Assess its current price and the adjustments your brewing method requires rather than assuming more settings automatically mean better coffee.
Key specifications
- Steel conical grinding mechanism.
- 39 selectable grind settings.
- 375g removable bean hopper.
- Integrated digital scale for weight-based dosing.
- Weight, number-of-cups and manual grinding programmes.
- Display and push-button controls, with a safety lock.
- Direct grinding into the supplied container or a suitable filter holder or portafilter.
- Removable hopper, grounds container and grinder ring; cleaning brush listed in the source package.
- Approximate source dimensions: 37.4cm high × 12cm wide × 22.7cm deep.
Check these details against the current retailer listing. We have not independently measured dimensions, dosing accuracy or grind distribution.
39 grind settings
The range runs from fine to coarse. The original review records Melitta's recommended starting ranges as 1–5 for espresso, 6–26 for filter and 27–39 for cafetière.
Use those as starting points, not universal recipes. Coffee, roast, brewing method and your results all affect the setting you choose.
For traditional espresso, the question is whether the steps allow sufficiently small changes for your equipment. A broad grinding range does not automatically provide the fine adjustment of a dedicated espresso-focused grinder.
Integrated digital scale
Weight-based dosing lets you choose a coffee quantity in grams rather than estimating it from running time. That is useful when following a recipe and recording adjustments.
A built-in scale does not establish perfect accuracy under every condition. We have not tested dispensing error, retention or consistency for this article. Follow the instructions for positioning, taring and using the appropriate receiving container.
Three grinding programmes
- Weight: grind towards a selected coffee weight.
- Number of cups: select a serving-based quantity.
- Manual: control quantity through grinding time.
The choice makes the grinder approachable for a beginner while providing a more measured workflow as you develop recipes. Cup selection should not be treated as interchangeable with a specific weight.
The 375g hopper
The removable hopper has capacity for considerably more beans than a single brew requires. There is no need to keep it permanently full.
If you regularly change coffees, adding smaller quantities may suit your routine better than leaving a large supply in the hopper.
Grinding into different containers
The source review describes a high grounds outlet and tare function supporting the supplied container, suitable filter holders and portafilters.
Check the fit and setup instructions for your equipment. Support for portafilter use should not be read as a guarantee that every portafilter size or shape will work equally well.
Cleaning and maintenance
The hopper, grounds container and grinder ring can be removed for cleaning, and the source package includes a brush.
The original review records Melitta's removable components as not dishwasher-proof. Follow the model-specific cleaning instructions, keep the grinding mechanism dry and do not assume removable means dishwasher-safe.
Who is it best for?
Consider the Calibra if you want an adjustable electric conical grinder for filter, pour-over, AeroPress or cafetière, and value dosing by weight. It may also suit a household switching between brewing methods and wanting a more repeatable recipe routine.
The integrated scale is the feature to judge against your needs. If you already have a weighing workflow you like, decide whether the convenience justifies the price difference over simpler alternatives.
Who should look elsewhere?
Someone wanting only a basic route away from pre-ground coffee may not need the Calibra's dosing features. At the other end, buyers focused on demanding traditional espresso should assess whether a specialist grinder offers more suitable fine adjustment.
Choose for the actual workflow rather than assuming one grinder will suit every brewing method equally well.
Calibra versus Molino
The Melitta Molino is the simpler proposition: a disc mechanism, 17 settings and straightforward cup-based quantity control.
The Calibra adds a steel conical mechanism, 39 settings, a larger hopper and an integrated scale. If your aim is simply to start exploring grind size, the Molino may cover that requirement. If dose measurement and a broader range matter, the Calibra offers additional features worth comparing.
Do you still need a brewing scale?
For recipe-based brewing, a separate scale remains useful. The Calibra measures coffee during grinding; it does not measure water being poured into your brewer or the beverage produced by an espresso machine.
A brewing scale, particularly one with a timer, serves a different part of the process. The integrated grinder scale reduces one source of guesswork without replacing every weighing task.
Our take
The Calibra offers a useful combination for a measured home-brewing routine: grind adjustment and weight-based coffee dosing in one appliance.
Its strongest appeal is to buyers using several brewing methods or following recipes by weight. Espresso-focused buyers should still assess fine adjustment carefully, while beginners should decide whether they need the additional features over a simpler grinder.
