Espresso Machines with Auto-Steam Options
There are two kinds of espresso machines, those with manual steam wands (traditional) and those with automatic milk frothers (auto-steam wands) built-in.
Auto-steam wand: With an auto steam wand, all you have to do is press a button and the machine does all the hard work for you. These are ideal if you have several different users creating drinks - this will help to keep beverages consistent from user to user.
