I'm right now in the process of rewriting the espresso classes for the SCAA conference this year in Long Beach; we've got nearly 8 hours worth of content developed (boiled down from probably a week's worth), which only scratches the surface of what a retailer should know to produce espresso and some espresso-based beverages.
