My new La Marzocco GB5 2grp Paddle came in yesterday. As with any new equipment delivery, I just couldn't wait to rip off the plastic wrap and pull the top of the box off so I would drool over the beauty of a new GB5! When I got to the portafilters, I pulled them out of the bubble wrap and noticed that they were different than the last ones we got with our GB5 3grp semi-auto just a few months back! The two main differences were that the spouts, which are newly designed themselves, now pop on and off with ease. They are held snug onto the portafilter by a rubber o-ring, with a notch cut out to align when popping on. This new design makes for easy and quick access for cleaning and scrubbing, which is pretty nice!
The portafilter also has a little "ledge" molded into the bottom of the front side of the body. The only thing I can guess is the it was added to keep the portafilter level or to keep it from slipping off the edge of the counter for those that set the portafilter on the edge while tamping. Has anyone else seen these new portafilters? Am I correct in my assumptions as to what the new features are intended for?
