Miele CM 7750 review: three bean hoppers, ten profiles, a touchscreen and automatic descaling in one flagship machine
The Miele CM 7750 Automatic Espresso Machine keeps three different coffees ready at once, remembers ten people, moves its own spout to your cup and even descales itself from a cartridge. It makes excellent espresso and milk drinks, but it is big, heavy and more machine than a small household needs.

In this review
Yes, if your household drinks different coffees and you have the counter for it. The Miele CM 7750 is the most flexible machine I tested: regular, espresso and decaf beans side by side, ten named profiles, a clear touchscreen, a glass milk container and AutoDescale that takes the worst job off your list. Espresso and milk drinks are both excellent. It's large, heavy and full of features a couple who drink one coffee won't use, and voice control works with Alexa only.

First impressions of the Miele CM 7750
The CM 7750 is big.
That was my first thought when I slid it out of the box, and it stayed true for four weeks.
At about 12 inches wide and 31 pounds, it's a commitment of counter space.
My second thought came the next morning.
I made an espresso from the espresso roast, my partner made a flat white from the everyday blend and a guest made a decaf latte macchiato.
Three different coffees, three different drinks, and nobody touched a bean or a setting.
That's what the Miele CM 7750 is for.
The touchscreen is clear and smartphone-like.
The spout dropped down to meet my small espresso cup on its own.
And the first cappuccino had the dense, fine foam I've come to expect from Miele, in a glass container that went straight back into the fridge.
The CM 7750 needs a generous stretch of counter.
What surprised me most
I expected the three hoppers to be a novelty.
Within a week, they changed how we used the machine.
Decaf after dinner stopped being a hassle, and I started keeping a special espresso roast just for straight shots.
What the Miele CM 7750 actually is
The CM 7750 is Miele's flagship countertop, bean-to-cup coffee machine.
Its headline feature is CoffeeSelect: three separate bean hoppers feeding one grinder.
Add the pre-ground chute, and you have four ways to make coffee.
It grinds the selected beans, brews them in an expanding chamber, and handles milk drinks through a tube from a glass container.
On top of that, it has ten profiles, a touchscreen, a self-adjusting spout, a heated cup warmer and automatic descaling.
The drinks
The home screen has shortcuts for espresso, coffee, cappuccino and latte macchiato.
Everything else is a swipe away.
| Drink | How it's made | Milk used |
|---|---|---|
| Espresso and ristretto | Short, concentrated brew | None |
| Coffee and long coffee | Longer brews for cups and mugs | None |
| Espresso macchiato | Espresso with a little milk foam | A little foam |
| Cappuccino | Espresso with a tall layer of foam | Foam |
| Flat white | Espresso with silky milk, about 4 to 6 oz | Milk and foam |
| Latte macchiato | Milk, foam and espresso, layered | Milk and foam |
| Hot milk and milk froth | Milk only | Milk |
| Coffee pot and teapot | Larger volumes for guests | None |
Miele CM 7750 design and setup
The CM 7750 measures about 16.6 × 12.25 × 17.5 inches, or 42 × 31.1 × 44.5 cm.
It weighs about 31 pounds.
Measure twice.
At over 16 inches tall, it fits under most standard cabinets, but you need room to open the hoppers on top.
Our tip: Leave a few inches above the machine, because all three bean hoppers open from the top.
The side door
A magnetic door on the side hides the pre-ground chute and its scoop, the grind adjuster, the milk tube holder and the brew unit.
The panel flexes a little as you pull it open, which feels less solid than the rest of the machine, but it closes neatly.
Cup warmer and lighting
The top is a heated, illuminated cup warmer.
Both the heat and the light can be switched off in the settings.
I kept the heat on and turned the light off at night.
First-time setup
Setup took about 20 minutes, including filling three hoppers and naming them.
I called mine Crema, Espresso and Decaf, so the touchscreen showed exactly what each one held.
The three bean hoppers sit side by side under one lid on top.
Three bean hoppers in daily life
CoffeeSelect is the reason to buy this machine.
I kept an everyday medium-dark blend, a darker espresso roast and a decaf in the three hoppers.
| Hopper | What I kept in it | Used for |
|---|---|---|
| Hopper 1, about 210 g | Everyday medium-dark blend | Coffee, cappuccinos, lattes |
| Hopper 2, about 180 g | Espresso roast | Straight espresso and ristretto |
| Hopper 3, about 150 g | Decaf | Evening drinks |
| Pre-ground chute | Occasional gift coffee | One-off drinks |
Choosing a bean
If a drink isn't assigned to a hopper, the touchscreen asks which bean you want before brewing.
If you assign one, the machine just uses it.
I locked my evening flat white to the decaf hopper and left everything else open.
That gave me one-press decaf at night and full choice during the day.
Does the coffee mix?
Barely.
A blower clears leftover grounds from the grinder path between drinks.
I switched from espresso roast to decaf and back many times and never tasted the previous bean in the next cup.
For anyone who needs genuine decaf in the evening, that matters.
The grinder
The CM 7750 grinds with steel conical burrs✕Conical burrsA cone-shaped cutting part that turns inside a ring. They grind evenly at fairly low speed, which keeps heat and noise down..
The grind adjuster is behind the side door.
Larger dots mean coarser, smaller dots mean finer.
I moved one step finer for the espresso roast.
Because all three hoppers share one grinder, the grind setting applies to every bean, so I picked a setting that suited all three.
Bars show how much resistance the coffee puts up and how long the water stays in contact with it.
Our tip: Choose beans with similar roast levels for the three hoppers, because they share one grind setting.
Miele CM 7750 espresso performance
The CM 7750 makes excellent espresso for a fully automatic machine.
With the espresso roast, I got a thick, hazelnut crema✕CremaThe golden-brown foam on top of an espresso. It forms when pressure pushes gases and oils out of freshly ground coffee., a round body and flavors of dark chocolate, roasted nuts and a little dried fruit.
Bitterness was low.
Having a dedicated espresso roast in its own hopper made a bigger difference than any setting.
My ratings on a 10-point scale for body, crema and flavor.
Settings you can save
Coffee amount, portion, temperature and pre-brewing✕Pre-brewingA short soak of the coffee before full pressure, also called pre-infusion. It lets the puck swell evenly so water doesn't rush through weak spots. can be set per drink and saved to each profile.
| What you taste or see | Likely cause | First change |
|---|---|---|
| Sour, thin | Under-extraction | More coffee, finer grind or DoubleShot |
| Bitter, harsh | Over-extraction or very dark beans | Shorter portion or one step coarser |
| Pale crema | Stale beans | Fresh beans in that hopper |
| Lukewarm | Cold cup | Use the heated cup warmer |
Long coffee, Americanos and DoubleShot
Long coffee from the CM 7750 is smooth and clean, especially with the medium-dark blend.
At a normal mug size, it had a light crema and a rounded, chocolatey taste.
When I pushed the portion very large, it started to taste thin.
That's where DoubleShot comes in.
It brews two portions of coffee into the same drink, so a big mug keeps its body.
I set DoubleShot on my morning long coffee and never changed it back.
My ratings on a 10-point scale for body and flavor, same beans and cup size.
For a cleaner long drink, hot water from the machine over a double espresso also worked well.
Our tip: Turn on DoubleShot for any mug over about 6 ounces, so the coffee stays full-bodied to the bottom.
Milk drinks and the glass container
The CM 7750 comes with a glass milk container of about 0.7 liters.
A tube connects it to the spout, and the machine handles the rest.
When you're not using milk, the tube stores in its own holder behind the side door.
How the foam turned out
Cappuccinos had a thick, glossy cap of fine foam.
Latte macchiatos layered neatly.
Flat whites were silky and the right size, about 4 to 6 ounces.
My ratings on a 10-point scale for texture, stability and temperature.
DoubleShot for milk drinks
DoubleShot brews two espresso shots without adding more milk.
On a flat white, that gives a strong, coffee-forward drink that still fits a small cup.
It became my default.
Our tip: Put the glass container back in the fridge straight after the milk rinse, so the milk stays cold for the next drink.
The glass milk container is included and lives in the fridge between drinks.
Touchscreen, profiles and the CupSensor
The touchscreen works like a phone.
Swipe through drinks, tap to choose, tap again to change settings.
Profiles, the maintenance menu and settings each have their own clear section.
Ten profiles
There are ten profiles, and names can be up to eight characters.
Each person's profile shows only the drinks they've saved, so the screen stays uncluttered.
The CupSensor
Put a cup under the spout, and the CupSensor detects it and lowers the spout.
It worked well with espresso cups, mugs and tall glasses.
I switched it off for one week to compare, and I missed it.
Two drinks and DoubleShot
The two-drink option makes two servings in one go.
DoubleShot makes one stronger drink.
They're different buttons for different jobs, and I used both daily.
Tea, the teapot and the coffee pot
The CM 7750 has tea programs at different temperatures for different teas.
There's also a teapot function for a larger volume of hot water and a coffee pot function for guests.
When family visited, I made a full pot of coffee and a pot of hot water for tea without standing at the machine for twenty minutes.
| Function | What it does | When I used it |
|---|---|---|
| Tea programs | Water at the right temperature for each tea | Afternoon green tea |
| Teapot | A larger volume of hot water | Family visits |
| Coffee pot | A larger volume of coffee | Weekend breakfasts |
Temperature and the heated cup warmer
With the heated cup warmer on, my espresso measured about 72°C in the cup.
From a cold cup, it was about 66°C.
Milk drinks finished around 60 to 65°C, and long coffee around 70°C.
Probe readings straight after brewing.
Cleaning and maintaining the Miele CM 7750
The CM 7750 does more of its own maintenance than any other machine I tested.
AutoDescale uses a cartridge inserted from the back, so you don't run descaling✕DescalingRunning a mild acid solution through the machine to dissolve mineral scale left by hard water. Scale slows heating and can block pipes. tablets by hand.
The milk pipework rinses automatically.
The maintenance menu on the touchscreen covers everything else.
The brew unit
Open the side door, press the red button, turn the yellow handle and slide the brew unit out.
I rinsed it weekly and left it to dry overnight before putting it back.
| When | Task | Why it matters |
|---|---|---|
| After milk drinks | Automatic milk rinse | Clears milk from the tube and spout |
| Daily | Empty the drip tray | The grounds bin holds about 16 pucks |
| Daily | Wash the glass milk container | Keeps milk fresh |
| Weekly | Rinse the brew unit, dry overnight | Removes coffee oils |
| When prompted | Cleaning programs and AutoDescale cartridge | Keeps oils and scale under control |
My estimate of hands-on cleaning time per day.
Several parts, including the grounds container, drip tray, water tank and milk container, are dishwasher-safe.
What daily use is really like
The CM 7750 is quiet for its size, with a muffled grinder.
I measured about 60 to 63 dB while grinding and about 55 dB while brewing.
Phone sound meter readings at about 50 cm.
With four of us, the 2.2-liter tank lasted about a day and a half, and the 16-puck bin needed emptying every other day.
Rough maths from a 2.2 L tank, allowing for rinse water. Actual numbers depend on cup size.
A typical morning
Glass container out, tap your profile, tap your drink, put the cup down.
The spout found the cup, the bean was already chosen and the drink was ready in about a minute.
The whole family round of four drinks took about six minutes.
The CupSensor lowers the spout to meet each cup.
A typical day with the CM 7750
By week three, the machine had settled into our day.
At 6:30, I tapped my profile and a ristretto from the espresso roast.
At 7:00, my partner tapped hers for a flat white with DoubleShot, and our teenager made a latte macchiato.
At lunch, a long coffee with DoubleShot.
In the afternoon, green tea from the tea program.
After dinner, a decaf flat white, locked to the decaf hopper, with one press.
| Time | Who | Drink and bean |
|---|---|---|
| 6:30 | Me | Ristretto, espresso roast |
| 7:00 | Partner | Flat white with DoubleShot, everyday blend |
| 7:15 | Teenager | Latte macchiato, everyday blend |
| 12:30 | Me | Long coffee with DoubleShot |
| 15:00 | Partner | Green tea program |
| 20:00 | Everyone | Decaf flat white, decaf hopper |
Our tip: Lock your evening drink to the decaf hopper, so late coffee is always decaf with one press.
That evening decaf, without swapping beans or using pre-ground, was the single biggest quality-of-life upgrade over a one-hopper machine.
Small details I came to appreciate
The CupSensor sounds like a gimmick until you use it.
The spout meets every cup at the right height, so espresso doesn't splash and crema doesn't break up on the way down.
The illuminated cup warmer looks good in the evening and can be switched off.
The milk tube has its own holder behind the side door, so it never dangles on the counter.
The touchscreen shows hopper names, so you always know which bean you're about to use.
And AutoDescale removes the job most owners forget.
| Detail | Why it helped |
|---|---|
| CupSensor spout | No splashing, no adjusting |
| Named hoppers on screen | No guessing which bean is which |
| Milk tube holder | Tidy counter |
| Switchable cup warmer and light | Warm cups, dark kitchen at night |
| AutoDescale cartridge | One less job to remember |
Our tip: Name each hopper after the bean inside, so everyone picks the right coffee on the touchscreen.
Wi-Fi and voice control
The CM 7750 connects to the Miele app over Wi-Fi.
It also works with Amazon Alexa, so you can ask for a drink if your cup is already under the spout.
Google Assistant didn't work in my testing.
I used voice control a few times, but the touchscreen was quicker.
Living with the CM 7750 long term
A flagship machine should last, and the CM 7750 is designed with that in mind.
AutoDescale protects the heating system without relying on you to remember a descaling cycle.
The removable brew unit is easy to reach, rinse and dry, which is the most important habit for any automatic machine.
Dishwasher-safe parts, including the water tank, drip tray, grounds container and milk container, take the effort out of weekly cleaning.
Running costs are descaling cartridges, cleaning tablets and filters.
The one thing to plan for is space.
Once the CM 7750 is on your counter, it isn't going anywhere, so choose its spot carefully, with room above for the hoppers and to the side for the tank and service door.
| Ongoing cost or task | How often | Notes |
|---|---|---|
| AutoDescale cartridge | When prompted | Depends on water hardness |
| Cleaning tablets | When prompted | For the brew system |
| Water filter | Every few months | If you use one |
| Brew unit rinse | Weekly | Dry overnight |
| Milk container wash | Daily | Dishwasher-safe |
How the CM 7750 fits different households
| Household | How well it fits | Main reason |
|---|---|---|
| Family with decaf and regular drinkers | Excellent | Three hoppers, no mixing |
| Five or more coffee drinkers | Excellent | Ten named profiles |
| Espresso enthusiast | Very good | Dedicated espresso roast hopper |
| Couple drinking one coffee | Fair | Most features unused |
| Small kitchen | Poor | Large footprint |
The decaf drinker
Decaf without compromise is the CM 7750's quiet superpower.
No swapping hoppers, no pre-ground decaf, and almost no carryover from the previous bean.
The espresso enthusiast
A dedicated hopper for an espresso roast means your straight shots always use the right bean, while everyone else's milk drinks use a cheaper blend.
The big family
Ten profiles is more than most families need, but it means guests, grandparents and teenagers can all have their own.
The couple
If you both drink the same coffee, you'll pay for hoppers and profiles you won't use.
Who it's really for
The CM 7750 shines when several people want different things from the same machine.
If that's not your house, a smaller Miele will make the same quality of drinks in much less space.
My four weeks with the CM 7750, week by week
| Week | What I focused on | Main change |
|---|---|---|
| 1 | Setup, hoppers and profiles | Three named hoppers, four profiles |
| 2 | Espresso and grind | One step finer, espresso roast in its own hopper |
| 3 | Milk drinks, DoubleShot and pots | DoubleShot flat white, coffee pot for visitors |
| 4 | Routine and AutoDescale | Weekly brew unit rinse, first AutoDescale cycle |
By week four, the three hoppers felt essential rather than clever.
Beans, water and milk
Use whole beans within a few weeks of the roast date.
Because the hoppers share one grind setting, choose beans with similar roast levels.
Avoid very oily or flavored beans, which can clog the grinder.
| Bean type | Espresso | Milk drinks |
|---|---|---|
| Medium-dark blend | Very good | Excellent |
| Espresso roast | Excellent | Excellent |
| Decaf | Good | Very good |
| Very dark, oily | Not recommended | Not recommended |
Use fresh, cold water and set the hardness so maintenance is accurate.
Common mistakes to avoid
The Miele CM 7750 is easy to live with, but a few habits will hold it back.
| Mistake | What happens | Better habit |
|---|---|---|
| Assigning beans to every drink | No choice at brew time | Lock only the drinks you never vary |
| Very different roasts in the hoppers | One grind can't suit all three | Pick similar roast levels |
| No room above the machine | Hard to fill the hoppers | Leave clearance on top |
| Putting the brew unit back wet | Moisture inside | Let it dry overnight |
| Leaving milk out | Warm milk, weaker foam | Back in the fridge after the rinse |
What I would change
A smaller footprint, a sturdier side door and Google Assistant support.
Is the Miele CM 7750 worth the money?
The CM 7750 is a flagship, and it's priced like one.
It earns that in a busy, varied household.
Three hoppers, ten profiles, a touchscreen, a self-adjusting spout and AutoDescale add up to the most convenient machine I tested.
Ask yourself three questions before you buy.
Do you drink more than one kind of coffee at home, such as regular and decaf?
Do three or more people share the machine?
Do you have the counter space?
If the answers are yes, the CM 7750 is easy to recommend.
If not, a smaller Miele will serve you just as well.
How it compares with Miele's smaller machines
The CM 7750 shares Miele's excellent milk system and expanding brew chamber with the smaller models.
What it adds is breadth: three beans, ten profiles, a touchscreen, a self-adjusting spout and automatic descaling.
If you'd use those every day, it's worth the extra space.
If you wouldn't, the drinks themselves won't taste dramatically different from a smaller Miele.
The one real compromise
Size is the only thing that held me back from calling it perfect.
In a narrow kitchen, it dominated the counter, and lifting it to clean underneath was a two-handed job.
Plan its spot before it arrives.
The CM 7750 is built for households that drink more than one kind of coffee.
How it compares with other espresso setups
The Miele CM 7750 stands out for its three hoppers, profiles and low-maintenance design.
| Feature | Miele CM 7750 | Single-hopper automatic | Manual machine and grinder |
|---|---|---|---|
| Bean choices at once | 3 plus pre-ground | 1 plus pre-ground | As many as you grind |
| Profiles | 10 | 0–8 | No |
| Spout | Adjusts itself | Manual | Fixed |
| Descaling | Automatic cartridge | Manual program | Manual |
| Milk container | Glass, included | Varies | Jug |
| Footprint | Large | Medium | Two appliances |
A single-hopper automatic can make drinks just as good, but switching to decaf means pre-ground coffee or emptying beans.
A manual setup gives you total control and unlimited beans, but each drink takes time and skill.
The CM 7750 is the most convenient way I've found to keep several coffees on tap for several people.
| You mostly drink | Is the CM 7750 a fit? | Why |
|---|---|---|
| Regular and decaf | Excellent | Separate hoppers, no mixing |
| Espresso | Very good | Dedicated espresso roast |
| Cappuccinos and flat whites | Excellent | Fine foam, DoubleShot |
| Tea and coffee for guests | Excellent | Teapot and coffee pot |
| One coffee, one person | Fair | Too much machine |
The full package: touchscreen, three hoppers on top and the central spout.

4 quick questionsMiele CM 7750 specifications
From manufacturer data and my own testing.
How I tested and scored the Miele CM 7750
For four weeks, I used the Miele CM 7750 as the everyday machine for a household of four, with a medium-dark blend, an espresso roast and a decaf in the three hoppers.
I set up four profiles, switched between all three beans many times a day, assigned beans to some drinks and left others open, tested DoubleShot, the two-drink option, the coffee pot and teapot, and adjusted the grind.
I made milk drinks with whole, 2% and barista oat milk, measured temperatures with a probe and noise with a phone meter at about 50 cm, and ran the cleaning programs and an AutoDescale cycle.
Michael and a second HouseholdMe tester shared the machine and wrote the notes together. We then checked our notes against Miele's specifications and owner documentation.
- Espresso (8.8): body, crema, flavor and consistency across three beans.
- Milk drinks (9.0): foam texture, temperature, the glass container and flat whites with DoubleShot.
- Ease of use (8.9): touchscreen, profiles, bean selection, CupSensor and setup.
- Cleaning (8.8): AutoDescale, brew unit access, milk rinsing and dishwasher-safe parts.
The overall score of 8.9 is an editorial rating that reflects those four areas.
