At a very basic level, an automatic coffee machine is one that takes at least some part of the coffee making process and does it for you. Quite what level of automation you get will vary by machine, however, which is why you’ll sometimes see machines referred to as anything from “Semi Automatic” to “Fully Automatic”, which kind of sounds like they’re getting coffee machines mixed up with machine guns, honestly.
What most of us think of – and what you’re most likely after from an “automatic” coffee machine – is a device that can make you a fresh cup of coffee at the touch of a button, taking much or all of the manual labour out of coffee production. You supply the beans and the water and it does most of the rest of it for you.
You can still get levels of service variance however, and this can relate to how fine-tuned you want your coffee experience to be. Some automatic machines will only offer a handful of grind or water settings, most will incorporate some kind of steam wand for frothing milk, while others may incorporate milk delivery as well.
