a button, and handling all the grinding, brewing, and steaming while you get on with making your breakfast, styling your hair, or just chilling on the
sofa for a couple of minutes. Unfortunately, you can easily lose that time later on when the machine needs cleaning.

Handling the whole coffee-making process inside a plastic box seems like a great idea (out of sight, out of mind), but the heat, moisture, and organic matter (i.e., coffee grounds) make the dark, steamy interior of your espresso machine an ideal breeding ground for bacteria and mold. Got a strong stomach? Here's what an unloved, unwashed brew unit will eventually look like , courtesy of the aptly-named subreddit r/MoldlyInteresting. "Heirloom culture fermented brew," observed one Redditor. "Aged in the dark. Price per cup: $35.00 USD." Latest Videos From Watch full video here:

It doesn't have to be that way, though. Emptying the drip tray and grounds
bin daily and cleaning the machine according to the instructions in the
manual are the first and most obvious steps.

However, manufacturers are now starting to add features that will help even further. Ninja just launched a coffee maker with a built-in fan , as you'd find in a PC case, which provides ventilation, and the KitchenAid KF4 has an excellent maintenance option that evaporates all water from the system in a satisfying cloud of steam.

stagnating water for two weeks while you're away on vacation.

After choosing the 'evaporate' option from the KF4's menu, you'll be prompted to remove the water tank (which you can wash and leave to air dry), then attach the hose for the milk system to the side of the coffee dispenser, push the other end into a hole in the drip tray, and place a large container under the dispenser spout. Then, stand back and watch as a surprising amount of water boils away, leaving everything perfectly dry and inhospitable to microorganisms. Get daily insight, inspiration and deals in your inbox Sign
