![]() ![]() Commercial lever machines almost universally were spring-cockers. This was something entirely unique to consumer espresso machines: the direct lever shot puller. And because your hand controlled the pressure, you could drive the pressure up or down during the shot pull. They did not include an internal spring: your hand was the spring. These companies introduced consumer espresso machines that used a direct lever system for pushing water at high pressure through a bed of coffee. That – in simplest terms – is pressure profiling an espresso shot, albeit in a very steady, straight downward sloping line.īelieve it or not, it is consumers – not commercial cafes and baristas – that really got to play with real pressure profiling as far back as the 1950s and 60s, thanks to several consumer machines put out by Gaggia, Faema and La Pavoni. The lever cocked an internal spring set up to deliver 7BAR of pressure to the brewing water at peak, but that pressure would decline over the shot pull as the spring unloaded. We’ve actually had pressure profiling available for espresso shots since modern day espresso was invented by Gaggia with their Crema lever espresso machine in 1947. What’s interesting is the pressure profiling part. The absolute bleeding edge of espresso exploration these days is found in three things: temperature stability, temperature profiling, and pressure profiling.

I have noticed the fast heating silicone cover accessory does help with my second shot in a row as the brew time of the first shot isn’t long enough for the kettle steam to heat the brew chamber on its own. I also have the pressure gauge and don’t notice much of a difference in the two portafilters, perhaps I apply less force to achieve the same pressure with the unscrewed restricted portafilter due to the added mesh screen. No portafilter cleaning until all the coffee is brewed. I use them interchangeably to make my shots for my wife and I on weekends. I have two brew chambers and pistons plus two restricted and two bottomless portafilters. I have a Neo and I bought the second shot plus and a pair of bottomless portafilters. There’s a mesh screen on the red restricted portafilter, but that seems to be the only difference. One interesting thing with the Flair is that the restricted flow portafilter from the Neo appears to be essentially the same as the bottomless once you unscrew the restricted flow part. ![]()
