Step 4 of 5
Continue pouring in manageable portions through the intended water distributor. Watch the fill level and flow.
Watch the fill level so nothing overflows.

Check the filter for damage and grind slightly coarser next time.
Check that the entire bed gets wet and no water bypasses it.
Why it works
With the Karlsbad or Bayreuth porcelain method, a brewing attachment sits on top of the pot. Its fixed filter base retains the grounds; the classic design does not use paper. Fine particles can still enter the drink. The mouthfeel may therefore be fuller and less clean than with a paper filter. Assembly and capacity vary by model.
Before use, check the instructions supplied with your pot. They determine assembly, fill quantity and care. The following quantities are a general starting point and must suit your pot’s size.
Check the porcelain for damage, particularly around the filter base. Loose parts, cracks or blocked openings are no reason to apply extra pressure. Assemble the dry parts once without hot water so you know how they fit. Place the pot on a stable surface and leave enough workspace to lift off the upper section later.
Choose a small quantity that suits your pot. As a calculated starting point, you can use 30 grams of coffee and 500 grams of water, provided your pot is designed for this. This is not a prescribed manufacturer value. Grind coarsely enough for the fixed filter to retain most of the grounds.
If a lot of grounds end up in the pot, start with a slightly coarser setting and check that the filter is intact. A grinder always produces some smaller particles too. Even a coarse average grind can therefore leave some sediment. A completely clear paper-filter result is not the only valid idea of good coffee.
If the coffee seems weak, do not immediately increase the dose. First check whether much water is bypassing the coffee bed or whether the bed is getting evenly wet at all. Pour steadily in a way that suits the water distributor. Uncontrolled flooding makes repetition harder and can cause overflow.
Keep the coffee quantity the same and change only the grind, by one small step. Record taste and sediment separately. You may prefer a slightly stronger cup with a pleasant mouthfeel even if it looks less clear. Do not judge solely by the bottom of the pot.
Carefully remove grounds from the openings without damaging them with hard tools. Use only cleaning agents and methods suitable for the product. Let all parts dry completely. Paperless means fewer consumables, but no less attention to care.
