So, I'm crazy about coffee. Here are my three favorite methods for making it at home!
The moka pot is a stove-top or electric coffee maker that brews coffee by passing boiling water pressurised by steam through ground coffee. Named after the Yemeni city of Mocha, it was invented by Italian engineer Alfonso Bialetti in 1933 and quickly became one of the staples of Italian culture. Bialetti Industries continues to produce the same model under the name "Moka Express".
Spreading from Italy, the moka pot is today most commonly used in Europe and in Latin America. It has become an iconic design, displayed in modern industrial art and design museums including the Wolfsonian-FIU, Museum of Modern Art, the Cooper–Hewitt, National Design Museum, the Design Museum, and the London Science Museum. Moka pots come in different sizes, making from one to eighteen 50 ml (2 imp fl oz; 2 US fl oz) servings. The original design and many current models are made from aluminium with Bakelite handles.
A French press, also known as a cafetière, cafetière à piston, caffettiera a stantuffo, press pot, coffee press, or coffee plunger, is a coffee brewing device, although it can also be used for other tasks. Two French inventors (Mayer and Delforge) patented in 1852 a forerunner of the French press. A patent was filed by a Frenchman, Marcel-Pierre Paquet dit Jolbert, officially published on August 5, 1924. In 1923 Ugo Paolini, an Italian, lodged patent documents relating to a tomato juice separator and he developed the idea of making a coffee pot with a press action and a filter. He assigned his 1928 patent to Italian designer Attilio Calimani and Giulio Moneta who filed it in 1929.
Brewing with a paper filter produces clear, light-bodied coffee. While free of sediments, such coffee is lacking in some of coffee's oils and essences; they have been trapped in the paper filter. Metal filters do not remove these components.
It may be observed, especially when using a tall, narrow carafe, that the coffee at the bottom of the coffeepot is stronger than that at the top. This is because less flavor is available for extraction from the coffee grounds as the brewing process progresses. A mathematical argument has been made that delivering comparable strength in two cups of coffee is nearly achieved using a Thue-Morse sequence of pours. This analysis prompted a whimsical article in the popular press.
There are several manual drip-brewing devices on the market, offering a little more control over brewing parameters than automatic machines, and which incorporate stopper valves and other innovations that offer greater control over steeping time and the proportion of coffee to water. There also exist small, portable, single-serving drip brew makers that only hold the filter and rest on top of a mug or cup, making them a popular option for backcountry campers and hikers. Hot water is poured in and drips directly into the cup.
A less familiar form of drip brewing is the reversible or "flip" pot commonly known as Napoletana.
