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.

Kan ni utföra en offsetkalibrering på min portafiltermaskin?

Det finns vissa argument mot offsetkalibrering för Lelit-portafiltermaskiner, särskilt för modeller som Lelit Bianca. Det handlar främst om komplexiteten och begränsningarna med offset som enda lösning på temperaturproblem:

  1. Temperaturfluktuationer och instabilitet. Offseten tar hänsyn till en konstant skillnad mellan panntemperaturen och bryggtemperaturen. I praktiken kan dock temperaturfluktuationer förekomma, t.ex. på grund av längre ståtider eller kontinuerlig bryggning. Därför kan den faktiska bryggningstemperaturen inte alltid förutsägas exakt.
  2. Beroende av omgivande förhållanden. Faktorer som rumstemperatur, luftfuktighet och maskinens skick (t.ex. uppvärmningstid) har ett betydande inflytande på bryggningstemperaturen. En fast offset kan inte kompensera dynamiskt för dessa variabler, vilket kan leda till felaktiga resultat.
  3. Värmeförlust under stilleståndstider. Efter längre pauser kyls brygggruppen ned och maskinen behöver tid för att återgå till önskad temperatur. En korrekt inställd offset kan inte kompensera för detta, varför ytterligare åtgärder som t.ex. en "kylspolning" är nödvändiga.
  4. Felaktiga fabrikskalibreringar. På vissa Lelit-modeller har det visat sig att fabriksoffset ofta är felaktigt inställd (t.ex. 4-8 grader för lågt på Lelit Bianca). Detta kräver manuell omkalibrering av specialiserad personal, vilket kan vara komplicerat för slutanvändarna.
  5. Missförstånd i tillämpningen. Många användare blir förvirrade av motsägelsefull information om offsetinställningen, vilket kan leda till felaktiga justeringar. Ofta tror man t.ex. att offseten ensam kan lösa alla temperaturproblem, trots att den bara är en del av ett mer komplext system.

Slutsats
Offsetkalibrering är ett användbart verktyg, men det bör inte betraktas som en isolerad åtgärd. För att uppnå optimala bryggresultat krävs en kombination av exakt PID-styrning, regelbundet underhåll och skräddarsydda tekniker (t.ex. sköljshots).
