引言回覆:
The machine is designed to use a pressurized portafilter, and produces LOTS of crema with the pressure valve in place. I removed the valve and tried a few shots, but they did not taste as good or have enough crema, and it was very difficult to make the shot last more than 15 seconds. I used the finest grind that I could muster and tamped very hard, but the shot was still underextracted. I suspect that the machine's designers didn't worry about the portafilter geometry, or depth of the coffee puck since they knew the valve would regulate the brew pressure and extraction time. It may also be true that the machine's pump flow rate is not high enough to produce enough pressure without the portafilter valve. I did some tests:

10.4 seconds per ounce at 7.5 bar (170 ml/min)

9.1 seconds per ounce at 5 bar (192 ml/min)

3.3 seconds per ounce at 0 bar (530 ml/min)

I am guessing that the pump is specifically sized so that the brew pressure will be about 7.5 bar and a double shot will take exactly 25 seconds.
