coffee steeping (infusion, full immersion) with drip-filtering (percolation
).

Overview

The idea to combine steeping with drip-filtering was utilized by

cake filtration
.

Marketed since spring 1927

moka and coffee filter ("Der beste Mokka- und Kaffeefilter der Welt").[2]

Properties were said to be:[2]

  • 100% porcelain, no contact with metal, enamel, or paper impacting the taste
  • paper filter
    or bags, thereby reducing costs
  • Claim to have no tendency of clogging the filter sieve holes (compared to Karlsbad-style coffee makers)
  • Full aroma, claimed to have up to 30% increased extraction efficiency (also called "Kaffeesparmaschine"), thereby reducing costs
  • Reduced amount of oily components and caffeine in finished coffee (will be floating on top of the water column in filter pot and claimed to be filtered out by settled coffee bed, a method sometimes called cake filtration)
  • Easy to clean by just washing out with water
  • Possibility to draw coffee from the coffee pot even before the coffee preparation process has stopped (just by temporarily opening the valve to draw a cup of coffee and then closing it again)
  • May need preheating of the porcelain due to longer than normal extraction time
  • Needs coarser than normal
    coffee grounds (semolina
    -grade)
