Reference excerpt

"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"). The properties were said to be:

100% porcelain, no contact with metal, enamel, or paper impacting the taste Permanent filter requiring no 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 been finished (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)

Worked examples

Example 1 — a first encounter with System Büttner coffee maker

Start with the simplest possible case. Write down what System Büttner coffee maker claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to System Büttner coffee maker before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about System Büttner coffee maker ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of System Büttner coffee maker

In research: System Büttner coffee maker appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses System Büttner coffee maker in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: System Büttner coffee maker is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coffee culture, Coffee in Germany, Coffee preparation, so understanding it makes those chapters shorter.
In everyday life: Look for System Büttner coffee maker outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
