Maintenance
EssentialDescaler
Limescale is what most machines die of, and vinegar attacks the seals. A liquid descaler declared suitable for espresso machines does the same job as the maker’s own branded fluid, usually for less.

When the Authentic+ C90 drops
Espresso machines drop hardest around Black Friday and in the weeks before Christmas. Leave your email address and pick below what you want to hear about.
The Authentic+ is a simple portafilter machine with a boiler and a 52 mm portafilter. You brew with ground coffee or with E.S.E. pods, for which a separate pod filter is in the box, and choose between coffee, steam and hot water with one button. The hot water is there for americano or tea.
The baskets are pressurised; Krups intends such baskets for pre-ground coffee. You froth milk yourself with the stainless steel steam wand; the water tank holds 2 litres. There is no grinder. The Authentic C50 is the same idea without hot water and without the pod filter.
Who for: Anyone starting with a portafilter machine on pre-ground coffee or pods.

This is what we know for certain. Dimensions and capacities the manufacturer or the shop does not state are left out rather than estimated. A measurement or a tank volume that is not there is one we do not have.
What does it cost a year to maintain?
A worked example, not a specification: 2 cups a day (730 a year), the intervals from the maker's manual, with the water filter the maker recommends, and the lowest price in our catalog today.
- Descaler
- Not stated
- The machine says when: the lights blink ten times when it is switched on. Krups gives no interval.
We cannot price anything for this machine: what the maker requires is not in our catalog, or the maker gives no interval.
How often you descale depends on your water hardness. Where the maker gives no interval for it, we leave it out rather than estimate it.
Beans, counted separately
6.57 kilos a year at 9 grams a cup: €108.34 with the cheapest kilo in our catalog, €445.45 with the dearest.

Accessories that fit this machine
Picked on what this machine does and does not do itself
Milk
EssentialMilk jug
A stainless jug of around 600 ml is the difference between milk that froths and milk that boils. The shape of the spout decides whether you can pour anything with it.
€12.95

Grinding
EssentialCoffee grinder
Without a grinder in the machine this is not an accessory but a second purchase. Budget something close to the machine itself. On pre-ground coffee no portafilter machine gives you what it can do.

Brewing
RecommendedKnock box
The puck has to go somewhere, and the bin clogs with wet coffee within a week. A box with a rubber bar is quieter than it sounds.

Brewing
Can waitCoffee scale
Dosing by eye is why the same machine tastes better on one day than the next. A scale accurate to a tenth of a gram, with a timer, turns pulling espresso into something repeatable.

Go to bolBeans for this machine
Every bean fits every machine. What differs is the order: on a bean-to-cup the 100% arabica beans come first, because dark-roasted blends carrying robusta give off more oil and that clogs a built-in grinder sooner.
