Almost identical to Albert Cohn's first patented design (see drawing on the right) dated 1910, his early Cona was still a crude chemist’s laboratory contraption, known as an "extraction column". Despite this, the authentic Conas continued to be manufactured by the company Cona Ltd. (since 2017 moved to the Netherlands), the only one that since that time continues to maintain the same original Napier design. In fact, it was this manufacturer who would rename these machines to put his name as you know them today. Parts of a Cona Coffee Maker The general rule when using a percolator is 1 tablespoon of coarse-ground coffee for every cup of water. This simple 1:1 ratio should consistently brew a rich and delicious cup of joe. That being said, percolator owners should feel free to experiment with their own coffee-to-water measurements to find the flavor that best suits their taste.

A Moka Pot is a brewing device designed to make rich, espresso-like coffee. It usually heats up on the stovetop, although there are electric models too. It has a similar appearance to a coffee percolator but works quite differently and produces a different coffee experience. The biggest difference between the two is pressure, according to Logan Allender of Atlas Coffee Club: To simplify our production and world-wide sales, we continued manufacturing the Size D = 1.13 Litre only, which throughout the decades has been the most popular choice by far. Idealy it serves 6 to 8 cups of coffee, but is also well suited to brew only 4 cups. All components of the new D-Genius fit as replacement part for any Cona Size D made from 1962 upto the present day. The Cona Rex was his first Cona re- design. It was taken into production in 1953. The shape features many characteristics of the early 1950s. To make our case, just compare it with the Porsche convertible 1950’s actor James Dean crashed in, or with the Jaguar Mark II many of us associate with the BBC TV- series ‘Inspector Morse’ or ‘Endeavour’. These then fashionable drop shapes were obtained by sheet metal processing techniques such as ‘rolling’ and ‘forcing’. Shapes that first evolved in supersonic fighter planes. The wider public came to embrace its aerodynamic shape and ditto styling, whilst in the military the propellor- driven Spitfire fighter was being replaced. From the scrapped thin aluminum plating of war planes such as the Spitfire, the first prototype versions of the Cona Rex were made. With other lesser brands a plastic fluted dish, often needing a (disposable) cloth or filter paper, acts as the separator. This dish is held in position by a steel spring hooked on the bottom of the spout. An unnecessary compromise.The popular British poster designer Abram Games shortly after the second world war came to meet a director of the Cona Coffee Machine Company. He argued, that the design of his basic Cona device could be improved, notwithstanding the delicious coffee that he made with it every day.

The Cona coffee maker consists of 2 independent spherical vessels and they join each other. At the top there is a tube attached to the bottom through which the liquid can rise, similar to Italian coffee machines. Too includes a filter at the base of the upper container. You should use preferably mineral water of weak mineralization so as not to add a bad flavor to the coffee. Or you can buy a water distiller or filter it by other methods. Abram Games had asked himself important questions in search of a better design, and found creative answers, which have become quality features of every Cona produced since then.

The new 2019 'CONA Size D-Genius All-glass' is - in our opinion - the best siphon brewer ever made. It is the original benchmark. Now proudly made in the Netherlands, our icon of british industrial design by Abram Games remains 'a marvel of engineered inventions' and 'quality made in Europe'. Make a coffee in a Cona coffee maker or vacuum siphoning is a somewhat longer process, but it is not complicated at all if you follow these simple steps and tips: Prepare coffee in a Cona coffee maker step by step As the technique is not so perfected to create the glass, on occasion they ended up exploding if care was not taken to remove them from the fire in time. When you wash the coffee pot, always do it without using soap. Just rinse with water so as not to affect the aroma, as is done with Italian coffee machines by expert baristas. Of course, wash it after each use so that it does not accumulate residues. The vacuum coffee maker was created by Loeff of Berlin, in 1830. Ten years later, Robert Napier designed a model derived from the first to make coffee using vacuum and would name it The Napier Vacuum Machine.

Accomplished and talented with pencil and paint, the artist Games had a very pragmatic approach to what deserved to carry his signature. He tested the quality of his work, long before he finished it, by seeking the honest opinion of friends and family on a work- in- progress. A lukewarm response, meant it was likely to end in the trash can. Only after he signed it, it would become part of his body of work. We timed this using the original Cona all- glass filter drainer, whilst brewing 6 cups. For 8 add one minute. For 4 deduct one. The Cona coffee maker, like any other coffee maker, has its advantages and disadvantages when compared to other types of coffee makers. The following are worth noting: Thanks to the (narrow) opening of the lower container joined to the two openings (a narrow one connected to the tube and a wider one in the upper area to be able to stir the coffee when it rises), you can prepare a coffee by heating this artifact. The normal glass used for pre- war glass coffeemakers was fragile. Shortly after the war ‘flame- proof ‘(also called 'Pyrex') glass was developed, and came onto the market in the early 1950’s. It offered an extraordinary resistance to temperature fluctuations.In addition, they were very expensive at the time, so few could afford to have one. The pyrex glass in which it was manufactured to withstand the high temperatures of the flame raised its price at that time when this material could not be produced as cheaply as it is now. El napier design became very popular at the time, laying the groundwork for its successors. In this way, at that time, a coffee free of impurities was obtained that could not be obtained by other methods.
