What could cause the separation of a shot off a superautomatic?
One of our techs sent me this picture, and said he has a customer that has a couple of supers in his home, and every once in a while he gets a shots that has clear separation. The bottom is thick and black, the top, almost straight water. Not having a ton of experience on troubleshooting supers, I am at a loss. Anyone know?

"super"-channeling? LOL. My only guess is that at least one layer is NOT water-based. Coffee and water have such similar densities that they are completely miscible. The only thing that comes to mind is the tablets used to clean the brew-group. Maybe some are trapped in the chute and are occasionally being extracted in addition to the coffee. The other possibility is that his machine has a love for scientific experimentation, and has centerfuged his espresso while he was away.
