Rocket Porta Via

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.

Der er nogle argumenter imod en offset-kalibrering på Lelit-espressomaskiner, især på modeller som Lelit Bianca. Disse vedrører primært kompleksiteten og begrænsningerne ved offset som den eneste løsning på temperaturproblemer:

1. Temperatursvingninger og ustabilitet. Offsettet tager højde for en konstant forskel mellem kedeltemperatur og brygtemperatur. I praksis kan der dog forekomme temperatursvingninger, f.eks. på grund af længere stilstandsperioder eller kontinuerlig brygning. Dette gør, at den faktiske brygtemperatur ikke altid er præcist forudsigelig.
   
2. Afhængighed af omgivelsesforhold. Faktorer som rumtemperatur, luftfugtighed og maskinens tilstand (f.eks. opvarmningstid) påvirker brygtemperaturen væsentligt. En fast offset kan ikke dynamisk udligne disse variabler, hvilket kan føre til unøjagtige resultater.
   
3. Varmeudslip ved stilstandsperioder. Efter længere pauser køler bryggruppen ned, og maskinen har brug for tid til at komme tilbage til den ønskede temperatur. En korrekt indstillet offset kan ikke kompensere for dette, hvorfor yderligere tiltag som en "Cooling Flush" er nødvendige.
   
4. Fejlkalibreringer fra fabrikken. Ved nogle Lelit-modeller er det konstateret, at offsettet ofte er unøjagtigt indstillet fra fabrikken (f.eks. 4-8 grader for lavt ved Lelit Bianca). Dette kræver en manuel efterkalibrering af fagfolk, hvilket kan være kompliceret for slutbrugere.
   
5. Misforståelser i anvendelsen. Mange brugere er forvirrede af modstridende oplysninger om offset-indstilling, hvilket kan føre til fejlagtige justeringer. For eksempel forventes det ofte, at offsettet alene løser alle temperaturproblemer, selvom det kun er en del af et mere komplekst system.
   

Konklusion
Offset-kalibrering er et nyttigt værktøj, men det bør ikke betragtes isoleret. En kombination af præcis PID-styring, regelmæssig vedligeholdelse og tilpassede teknikker (f.eks. skylle-skud) er nødvendig for at opnå optimale bryggeresultater.
