The part re: colloids is a trade secret at this point, but definitely a real challenge.

As far as we could find, there is no common solution for industrial scale espresso. If someone has one, please post it here. This was a personal obsession of mine last spring - "How does this not exist?!?"

Kalle is the coffee expert, but as the 'non-coffee guy', I have no idea why this wouldn't exist - I would have thought someone out there would need it?

industrial scale espresso: what about those automatic espresso machines you can sometimes find in office buildings? they pull single, double, or triple espresso shots from a touch screen interface. Can do lattes etc. too, but assuming you wouldn't need that part.

They're called super automatics. Generally, they're really expensive, and they make coffee very slowly (.5ml/second if you're lucky). They also tend to be built by companies who don't readily provide documentation on how to fix / modify them.
