I need to learn [ASAP] how to use an espresso machine for some very basic drinks, learning how to properly froth milk, etc. I won't be working in store so I don't need to learn anything store related, and I won't need to learn anything about roasting beans. I researched and found Counter Culture's class which sounds perfect but it isn't until May! And all other classes I found look extremely in depth. Does anyone have any ideas? Literally I would even take just going into a store and demo-ing an espresso machine! I've been watching videos online and I just want to try it out on a real machine a couple of times.
