What is a bean-to-cup coffee machine and is it worth it

How a bean-to-cup machine works

Inside, several parts work in sequence. Beans drop from the hopper into a burr grinder, which grinds a measured dose. The grounds fall through a chute into the brew unit, a removable chamber with a piston that compresses the coffee into a puck. A pump pushes hot water from a thermoblock heater through the puck at pressure, and the espresso runs out of the spout. The brew unit then ejects the used puck into the grounds bin.

Milk systems vary. Some machines have a steam wand you use by hand. Others draw milk from a carafe or a jug through a tube and froth it automatically. That is what makes one touch lattes and cappuccinos possible.

• Bean hopper and burr grinder: grinds fresh for each drink
• Brew unit: compresses the coffee and brews the shot
• Thermoblock: heats water quickly on demand
• Pump: pushes water through the coffee under pressure
• Milk system: steam wand or automatic carafe
• Grounds bin and drip tray: collect used pucks and waste water

What you get in the cup

Because beans are ground fresh, the coffee tastes fresher than from pods or pre-ground coffee. Results are consistent day to day. Most machines let you adjust strength, cup size, temperature and grind fineness, and many store profiles for different people.

The trade off is control. A bean-to-cup cannot be fine tuned shot by shot as a manual espresso machine can, and the doses are smaller than a café double, so espresso can taste lighter. Many people find a stronger setting and a medium roast bean give the best results.

Daily and weekly upkeep

Bean-to-cup machines automate brewing, not cleaning. Expect a few minutes of care each day and a little more each week. Skipping it is the main reason these machines develop faults.

Note:Follow your manual for cleaning products. Many makers say not to wash the brew unit with detergent or put it in a dishwasher.

Who gets the most from one

A bean-to-cup suits people who drink two or more espresso based drinks a day, households with several coffee drinkers, and anyone who wants café style milk drinks without learning barista skills. It also suits small offices. If you drink one black coffee a day, a filter machine or cafetière is simpler. If you love tweaking every shot, a manual espresso machine is more satisfying.

Is it worth it?

If you regularly buy coffee out, a bean-to-cup can work out cheaper per cup over time. Use our cost per cup calculator to see your own numbers, and allow for beans, milk, descaler and filters. It also saves time compared with a manual machine. Against that, these machines have more moving parts than a simple espresso machine, so regular care matters.

Frequently asked questions

What is the difference between bean-to-cup and espresso machines? A bean-to-cup does every step automatically. A manual espresso machine needs you to grind, dose, tamp and steam milk, which takes skill but gives more control.

Can you use pre-ground coffee in a bean-to-cup? Many models have a separate funnel for a single dose of pre-ground coffee, such as decaf. Never put ground coffee in the bean hopper.

Do bean-to-cup machines make proper espresso? They brew under pressure and produce crema, so yes. Shots are usually lighter than a café double because doses are smaller.

How long does a bean-to-cup machine last? With regular cleaning and descaling, many last for years. See how long do coffee machines last.
