I'm learning to brew coffee, and one of my aspirations is to be able to brew a good, solid cup of latte, with the milk foamed just right all the way through. I'm getting there, but beyond that point, I want to be able to create latte art. In a few months, I'll have to buy my own machine to practice on.
Our current machine (a small household unit with a copper boiler) has good pressure for foaming milk, but apparently that pressure isn't sufficient for being able to produce microfoam, which I understand is necessary for good latte art.
When I shop for a new machine, what qualities do I need from it to be able to properly produce latte art? I'm aware I need an angled wand, but I've heard conflicting reports on the amount of pressure involved and other factors.
