System Büttner coffee maker
coffee maker combining steeping with drip-filtering
"System Büttner" coffee makers (German: Büttner-Kaffeemaschine) have been a type of manual and semi-automatic coffee makers combining coffee steeping (infusion, full immersion) with drip-filtering (percolation).
Overview
The idea to combine steeping with drip-filtering was utilized by the Berlin-based coffee roaster Carl Artur Büttner (also written as Carl Arthur Büttner) in his 1926 invention of a manual zero-bypass flat bottom coffee maker consisting of four parts, all made out of porcelain: a filter pot (Filtergefäß / Oberteil, "O") with lid (Deckel, "D"), saucer (Ablaufteller / Unterteil, "U") and coffee pot (Kaffeekanne, "K"). The filter pot featured a through-glazed porcelain filter with triangularly-arranged slits with some air space below. The captured hot air causing mild micro-turbulences on the underside of the coffee grounds were said to help avoid clogging. Steeping was achieved utilizing a valving mechanism stopping the flow through the filter by a specially designed rotatable saucer with a single hole, which had to be positioned between the filter pot and the coffee pot so that the hole was initially closed and was manually opened when the coffee had been steeping for three to five minutes. Once released, it then took between three and six minutes for the coffee to drip through the meanwhile settled coffee bed into the coffee pot, a method sometimes also called cake filtration.
Marketed since spring 1927 and up into, at least, the 1940s, these coffee makers were available as stand-alone devices for home use, but were also adopted by various other German coffee roasters (including Maschinenfabrik Bremen (Bremen, Germany), Georg Schrader & Co. aka Geschraco (Bremen, Germany), Ferd + Eichhorn (Braunschweig, Germany), Heimbs & Sohn Co. (Braunschweig, Germany) and Columbus (Germany)) as part of larger coffee machines produced by the porcelain manufacturer Bauscher (Weiden, Germany) for heavy-duty semi-continuous batch use in restaurants and canteens. The Büttner extraction method was boldly marketed claiming to be the world's best moka and coffee filter ("Der beste Mokka- und Kaffeefilter der Welt").
This brief starts where responsible research should: with the source description of “System Büttner coffee maker” as coffee maker combining steeping with drip-filtering. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as coffee maker combining steeping with drip-filtering. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 4, 2026. The linked authority identifier is Q124421781. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1926 and 1927.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
