Hi, I'm just starting out with home made espresso and this is my first post, although read many. i am gradually getting better at making espresso however i notice that after i pull a shot (my terminology may not be accurate) and stop the pump, coffee will drip from the portafilter spout for some time. is this usual? I have a Gaggia color with a standard portafilter and am using the double shot basket.
Welcome to CG forums. I believe that the Color does not have a 3 way solenoid valve and therefore does not release pressure from the brew immediately, compare to the Gaggia Classic. This means that the pressure and a bit of liquid bleeds off through the puck and drips. You may also find that the portafilter remains very tight for a minute until that happens. If you manage to loosen it early you will be rewarded with a hot sprayed mess so do not try. It sounds like it is working normally.
+1 this is something that will just happen regardless if you don't have a 3 way valve. I used to have a little Delonghi and I was always in a rush when I made espresso. I used to kick on the steam for a minute after I pulled a shot to heat up the portafilter and dry out the puck. Granted I was using an aluminum portafilter. Yours is brass so it may take longer.
