Working a new machine

I've been doing a little consulting work recently and one of the side benefits is the place has a very nice semi-pro espresso machine and proper grinder, so I've been able to practice my espresso kung-fu on something new. It literally took me a year to learn how to use my Expobar well so I'm quite proud that with a fresh bag of Intelligentsia Black Cat I was able to produce acceptable shots almost immediately and great shots within a couple of days.

The machine is a double boiler Vibiemme and since it's in an office environment it gets much more use then my Brewtus and was filthy. Has no one hear of the portafilter-wiggle? I spent a little time each morning cleaning the machine and the Mazzer grinder to rid them both of the burnt Starbucks crap they've been eating for years. Now on a steady diet of Black Cat the pair are clean and happy and producing very good espresso. Now if I can just get people to replace the portafilter after they use it instead of leaving it on the tray.
