The U.S. division of La Marzocco, the Italian espresso machine manufacturer founded by the Bambi family, brings its "Pressure + Flow" tour to Los Angeles this month. On Feb. 13, La Marzocco will offer hands-on brewing lessons on its flagship Strada EP, which some called a game-changer and "the most advanced espresso machine on the planet" at the time of its unveiling.
Most espresso machines extract coffee at a set pressure of 8 to 9 bars (or atmospheres), but the Strada EP is capable of continuously variable extraction between 1 and 12 bars with computers and microcontrollers that adjust the speed of the pump motors rather than the barista having to do so by hand -- and then having to replicate it for each extraction. Pressure profiles can be recorded in the machine's memory system -- and it can even auto-correct for slight mistakes. Not to mention its gear pump system and membrane pentiometer ....
La Marzocco USA's Pressure + Flow four-city tour -- free and open to anyone who registers -- includes demonstrations and presentations on various coffee topics and hands-on experiences with the Strada EP.
During the "Pressure" session, hear about the development of the Strada EP and what La Marzocco has learned about brewing coffee on the machine.
