All Purpose grinding discs
Eureka burrs are specially designed to deliver outstanding results for both espresso and filter coffee. They are ideal for all types of coffee, especially light and medium roasts, as they bring out the clarity and brightness of the aromas.

Unlimited Stamina
Thanks to the innovative treatment technologies, the grinding discs offer greater durability than any other grinding disc treatment on the market.

Excellent grinding disc consistency
The thermal cryo-treatment cools the grinding discs down to -193°C. This technology makes the grinding discs particularly robust and provides two decisive advantages: a significantly longer service life and a consistently consistent grinding result without adjustment of the grinding level over time.

Ultra Low Retention & Wider Grinding Surface
The innovative system developed by Eureka enables the lowest retention ever. The wider grinding surface ensures a more consistent grinding result.

Black Diamond technology
The combination of cryogenic process and DLC coating (Diamond-Like Carbon) guarantees unique performance and durability. Studies by the University of Modena and Reggio Emilia (UNIMORE) show a durability improvement of +5% compared to Red Speed and +93% compared to stainless steel grinding discs.

No coffee loss
The grinding discs are ready for use immediately. Thanks to a special process developed by Eureka, the grinding discs do not need to be "run in", which prevents coffee loss.

Superior grinding consistency
The cryogenic treatment of the grinding discs at -193°C ensures greater wear resistance and maintains the grinding settings longer than any other grinding disc technology.

Diamond Inside grinding discs
Eureka's new patented process ensures a superior crystal structure of the grinding discs. Diamond Inside is a low-temperature thermal treatment process at -193°C that creates an increased crystal structure and thus guarantees superior wear resistance and durability.

This process helps to maintain the optimal geometry of the burrs longer than any other type of burr. The granulometry remains constant for an exceptionally high quantity of ground coffee: about 1300 kg with 65 mm burrs, with a total duration that can reach up to 1500/1600 kg.

Frequently Asked Questions

I bought a new coffee grinder from Naturbohne and there are coffee residues in it.

Please note: Some manufacturers test their coffee grinders before shipping, which means that small coffee residues or bean residues can occasionally be found in the grinder. This procedure is used to test functionality and is considered a quality feature. Of course, we only sell new products - unless expressly stated otherwise.

Static charge – coffee grounds spray out from the side

With some coffee grinders, the ground coffee can become statically charged and spray out of the portafilter at the side. This means that not all of the ground coffee gets into the portafilter, which can lead to uneven extraction. Our recommendation: Use a dosing funnel to ensure that all of the ground coffee is precisely fed into the portafilter - for optimal espresso enjoyment.

What is dead space in coffee grinders?

Conventional coffee grinders often leave a so-called dead space in which coffee residues accumulate. These residues can not only affect the freshness, but also lead to old and fresh coffee grounds being mixed, which negatively affects the taste. In contrast, single dose grinders have a well-thought-out design that eliminates the dead space. Each portion is ground individually and precisely so that no residues are left behind - for a consistently pure and full-bodied coffee experience.

Which portafilter fits my espresso machine?

When choosing the right portafilter for your portafilter machine, it is important to know that each manufacturer develops its own brewing group - the most well-known is the Faema E61. However, this does not mean that any portafilter will fit without any problems. An incompatible portafilter can leak, which will have a direct negative impact on the quality of your espresso. We therefore recommend using either the portafilter originally supplied or one that is explicitly stated to be compatible with your machine. This will ensure that the pressure is optimally built up and the espresso is perfectly extracted.

Can I visit you or pick up the goods personally?

Yes, of course, you are welcome to come by and look at our products by appointment. We would be happy to advise you personally. The best thing to do is to send us an email with a few suggested appointment times.

We are located 5 minutes from the motorway between Stuttgart and Lake Constance on the edge of the Black Forest.

Important note, first use coffee grinders

Another little tip for the perfect start with your new mill:

You will get the best grinding result after you have ground about 1-2 kg of beans. It is best to use a few cheap beans so that the grinder can work optimally. And if you are wondering what you can do with the bean flour - it is perfect plant fertilizer! 🌿

It contains nitrogen, potassium, sulfur and phosphorus and is a real nutrient bomb for your plants.

Můžete provést offset kalibraci na mém pákovém kávovaru?

Existuje několik argumentů, které hovoří proti kalibraci offsetu u kávovarů Lelit, zejména u modelů jako Lelit Bianca. Tyto argumenty se týkají především složitosti a omezení offsetu jako jediné řešení problémů s teplotou:

  1. Kolísání teploty a nestabilita. Offset zohledňuje konstantní rozdíl mezi teplotou kotle a teplotou vaření. V praxi však mohou nastat kolísání teploty, např. kvůli delším dobám stání nebo kontinuálnímu vaření. Tím pádem není skutečná teplota vaření vždy přesně předvídatelná.
  2. Závislost na podmínkách prostředí. Faktory jako teplota místnosti, vlhkost vzduchu a stav stroje (např. doba zahřívání) výrazně ovlivňují teplotu vaření. Pevný offset nemůže tyto proměnné dynamicky vyrovnat, což může vést k nepřesným výsledkům.
  3. Ztráta tepla při stání. Po delších přestávkách se vařící skupina ochladí a stroj potřebuje čas, aby se znovu dostal na požadovanou teplotu. Správně nastavený offset to nemůže kompenzovat, proto jsou nutná další opatření, jako je "Cooling Flush".
  4. Chybné kalibrace z výroby. U některých modelů Lelit bylo zjištěno, že offset je často z výroby nastaven nepřesně (např. o 4–8 stupňů nižší u Lelit Bianca). To vyžaduje manuální překalibraci odborným personálem, což může být pro koncové uživatele komplikované.
  5. Nedorozumění v aplikaci. Mnoho uživatelů je zmateno protichůdnými informacemi o nastavení offsetu, což může vést k nesprávným úpravám. Například se často očekává, že offset sám vyřeší všechny problémy s teplotou, i když je pouze součástí složitějšího systému.

Závěr
Kalibrace offsetu je užitečný nástroj, ale neměla by být považována za izolovanou. Kombinace přesného PID řízení, pravidelné údržby a přizpůsobených technik (např. vyplachovací záběry) je nezbytná pro dosažení optimálních výsledků vaření.
