Hi All! Our cafe just opened, and we decided to go with an Astoria Gloria Lever-driven espresso machine. While she's very sleek and very sexy, we have many questions about just how much control we have over several aspects of extraction. So far, it seems that all we can do is adjust the water temperature, which is now correct. For one, can you change the amount of water that is dispensed? Surely you must have the option of long and short shots. I mean, the machine came with a single shot portafilter insert, as well as two doubles. As it is, our shots fall just short of the white line on the shot glass, which I believe is for a 1 1/2 oz. shot. Maybe a longer pre-infusion? Also, I'm having a very hard time finding the sweet spot with the steaming wand pressure. It's either not enough, or it's spinning the milk out of control, making a pitcher full of sudsy-looking mess, and making me look like a clumsy fool in front of our customers!! I'm sure this will come with practice, but any advice would be helpful. Also, any links to discussions, etc., on Lever-driven machines are greatly and humbly appreciated! Cheers!
