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.

Czy można przeprowadzić kalibrację offsetową mojego ekspresu z portafiltrem?

Istnieją pewne argumenty przeciwko kalibracji offsetowej dla ekspresów z portafiltrem Lelit, szczególnie dla modeli takich jak Lelit Bianca. Odnoszą się one głównie do złożoności i ograniczeń offsetu jako jedynego rozwiązania problemów z temperaturą:

  1. Wahania temperatury i niestabilność. Offset uwzględnia stałą różnicę między temperaturą bojlera a temperaturą parzenia. W praktyce jednak mogą wystąpić wahania temperatury, np. z powodu dłuższego czasu leżakowania lub ciągłego parzenia. W rezultacie nie zawsze można precyzyjnie przewidzieć rzeczywistą temperaturę parzenia.
  2. Zależność od warunków otoczenia. Czynniki takie jak temperatura pomieszczenia, wilgotność i stan urządzenia (np. czas nagrzewania) mają znaczący wpływ na temperaturę parzenia. Stałe przesunięcie nie może dynamicznie kompensować tych zmiennych, co może prowadzić do niedokładnych wyników.
  3. Utrata ciepła podczas przestojów. Po dłuższych przerwach grupa parzenia stygnie, a urządzenie potrzebuje czasu, aby powrócić do żądanej temperatury. Prawidłowo ustawiony offset nie może tego skompensować, dlatego konieczne są dodatkowe środki, takie jak "płukanie chłodzące".
  4. Nieprawidłowe kalibracje fabryczne. W niektórych modelach Lelit stwierdzono, że fabryczny offset jest często ustawiony niedokładnie (np. 4-8 stopni za nisko w Lelit Bianca). Wymaga to ręcznej rekalibracji przez wyspecjalizowany personel, co może być skomplikowane dla użytkowników końcowych.
  5. Nieporozumienia w aplikacji. Wielu użytkowników jest zdezorientowanych sprzecznymi informacjami na temat ustawienia offsetu, co może prowadzić do nieprawidłowych regulacji. Na przykład, często oczekuje się, że samo przesunięcie rozwiąże wszystkie problemy związane z temperaturą, chociaż jest to tylko jedna część bardziej złożonego systemu.

Wniosek
Kalibracja offsetu jest użytecznym narzędziem, ale nie powinna być rozpatrywana w oderwaniu od innych czynników. Połączenie precyzyjnej kontroli PID, regularnej konserwacji i niestandardowych technik (np. płukania) jest niezbędne do osiągnięcia optymalnych wyników parzenia.
