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.

Vai varat veikt offset kalibrāciju manai portafiltera espresso mašīnai?

Ir vairāki argumenti, kas runā pret offset kalibrēšanu Lelit sviras tipa espresso aparātos, īpaši tādos modeļos kā Lelit Bianca. Tie galvenokārt attiecas uz offset kā vienīgā risinājuma sarežģītību un ierobežojumiem temperatūras problēmu gadījumā:

  1. Temperatūras svārstības un nestabilitāte. Offset ņem vērā pastāvīgu starpību starp katla un brūvēšanas temperatūru. Taču praksē var rasties temperatūras svārstības, piemēram, ilgstošas gaidīšanas vai nepārtrauktas brūvēšanas laikā. Tāpēc faktiskā brūvēšanas temperatūra ne vienmēr ir precīzi paredzama.
  2. Atkarība no apkārtējās vides apstākļiem. Tādi faktori kā telpas temperatūra, gaisa mitrums un iekārtas stāvoklis (piemēram, uzsildīšanas laiks) būtiski ietekmē brūvēšanas temperatūru. Fiksēts offset nevar dinamiski kompensēt šīs mainīgās vērtības, kas var radīt neprecīzus rezultātus.
  3. Siltuma zudumi paužu laikā. Pēc ilgākām pauzēm brūvēšanas grupa atdziest, un iekārtai nepieciešams laiks, lai atkal sasniegtu vēlamo temperatūru. Pareizi iestatīts offset to nevar kompensēt, tāpēc nepieciešami papildu pasākumi, piemēram, “Cooling Flush”.
  4. Nepareiza rūpnīcas kalibrācija. Dažiem Lelit modeļiem ir konstatēts, ka offset rūpnīcā bieži tiek iestatīts neprecīzi (piemēram, Lelit Bianca modelim tas ir par 4–8 grādiem zemāks). Tas prasa manuālu atkārtotu kalibrēšanu no speciālista puses, kas gala lietotājam var būt sarežģīti.
  5. Lietotāju neizpratne lietošanā. Daudzi lietotāji ir apjukuši pretrunīgas informācijas dēļ par offset iestatīšanu, kas var novest pie nepareizas pielāgošanas. Nereti tiek sagaidīts, ka tikai ar offset pietiks visu temperatūras problēmu risināšanai, lai gan tas ir tikai daļa no sarežģītākas sistēmas.

Kopsavilkums
Offset kalibrēšana ir noderīgs rīks, taču to nevajadzētu skatīt izolēti. Lai sasniegtu optimālus brūvēšanas rezultātus, nepieciešama precīza PID vadība, regulāra apkope un pielāgotas tehnikas (piemēram, skalošanas šāvieni).
