I learned how to make coffee like a barista. I purchased an espresso machine with a milk steamer, and learned how to make rudimentary latte/cappucino art.
What machine did you get, if you don't mind my asking? I haven't been able to find one that I'm confident is worth investing time into, as well as the financial investment.
Breville Barista Express. It comes with a built in grinder that doesn't have granular grind settings. I'm pretty happy with it at my skill level, though.
If I were to start over, I would get a cheaper, simpler Breville machine and put the difference into a nicer grinder. But this isn't compelling enough for me to actually start over.
