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.

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.

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.

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.

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.

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.

Obstaja nekaj argumentov proti offset-kalibraciji pri Lelit ročnih espresso aparatih, zlasti pri modelih, kot je Lelit Bianca. Ti se nanašajo predvsem na kompleksnost in omejitve offseta kot edine rešitve za temperaturne težave:

1. Temperaturna nihanja in nestabilnost. Offset upošteva stalno razliko med temperaturo kotla in temperaturo ekstrakcije. V praksi pa lahko pride do temperaturnih nihanj, npr. zaradi daljših premorov ali neprekinjenega pripravljanja kave. Zaradi tega dejanska temperatura ekstrakcije ni vedno natančno predvidljiva.
   
2. Odvisnost od okoljskih pogojev. Dejavniki, kot so temperatura prostora, vlažnost zraka in stanje aparata (npr. čas ogrevanja), močno vplivajo na temperaturo ekstrakcije. Fiksni offset teh spremenljivk ne more dinamično izravnati, kar lahko vodi do nenatančnih rezultatov.
   
3. Tople izgube pri daljših premorih. Po daljših premorih se skupina za pripravo ohladi in aparat potrebuje čas, da ponovno doseže želeno temperaturo. Pravilno nastavljen offset tega ne more nadomestiti, zato so potrebni dodatni ukrepi, kot je "cooling flush".
   
4. Nepravilna tovarniška kalibracija. Pri nekaterih modelih Lelit je bilo ugotovljeno, da je offset v tovarni pogosto nastavljen nenatančno (npr. 4–8 stopinj prenizko pri Lelit Bianca). To zahteva ročno naknadno kalibracijo s strani strokovnjakov, kar je za končne uporabnike lahko zapleteno.
   
5. Napačna uporaba. Veliko uporabnikov je zaradi nasprotujočih si informacij o nastavitvi offseta zmedenih, kar lahko privede do napačnih nastavitev. Pogosto se pričakuje, da bo offset sam rešil vse temperaturne težave, čeprav je le del bolj kompleksnega sistema.
   

Zaključek
Offset-kalibracija je uporabno orodje, vendar je ne gre obravnavati ločeno. Za optimalne rezultate pri pripravi kave je potrebna kombinacija natančnega PID-krmiljenja, rednega vzdrževanja in prilagojenih tehnik (npr. spiranih šotov).
