Moka brewing is the term used for Italy's most popular domestic method of brewing coffee.
This method produces coffee very similar to the early "espresso" that became popular in Italy during the first half of the 20th century. Hot water is forced through coffee grinds by the steam pressure, producing a strong, concentrated cup of coffee.
Present day espresso forces the coffee through the grinds at much higher pressures using pumping devices. This higher pressure creates a cup of coffee significantly different than Moka coffee. More flavors and oils are extracted. This can be seen in the emulsion ("crema") that caps the drink. This "true espresso" brewing came into being only towards the middle of the 20th century and has been popularized in coffee bars and for home use during the last years of the 20th century.
Moka Brewing might be better labeled as steam-pressure brewing but the Moka Pot is the most prevalent application used. This method uses a brewer that consists of:
A boiler unit
A coffee filter and funnel that dips into the boiler unit
A receiving receptacle for the brew
Gaskets and safety valves to insure a tightly closed unit to allow for pressure build up and a necessary security release if pressure gets too high.
The Bialetti company of Omegna, Italy has done the most to popularize this method of brewing and has developed a new model that claims to extract some oils and flavors similar to coffee brewed in the true espresso fashion.
Moka itself is a fairly large piece of code: Parsing and rendering Java code is not trivial, although in that respect Java is one of the simplest existing languages.
Moka is a contraction of "Mozart's Kafee" and is a Java front-end for a development environment called "Mozart." Mozart is a set of APIs, file formats, and utilities that help development tools cooperate and exchange information about the application under development.
Moka was the first front-end developed for Mozart, for a couple of reasons: Java is a simple language to parse, compared, for instance, to C++; and Java has a large audience, making Moka quite useful to many developers.
