KitchenAid KF6 vs KF7: which fully automatic KitchenAid should you buy?

KitchenAid KF6 vs KF7 at a glance

Head to head

The better result in each row is marked, based on my testing and the manufacturer specs. Rows where the machines are identical have no winner.

Keep in mind that the tally is not my verdict. Some rows matter far more than others, and which ones matter depends on what you drink.

Design, size and build

Put the two side by side and the family resemblance is complete. Both measure about 14.3 inches tall, 10.2 inches wide and 18.6 inches deep, and both weigh about 28 pounds.

That weight comes from a heavy, metal-clad body. Both feel far more solid than most fully automatic machines, with none of the hollow plastic feel common at this level.

The KF7’s touchscreen and color options make it the more striking of the two.

The faces are where they differ. The KitchenAid KF6 has a 2.4-inch color screen flanked by buttons, while the KitchenAid KF7 has a 3.5-inch color touchscreen.

The KF7 also comes in more colors. Both are offered in stainless steel, white and black, and the KF7 adds a Juniper green that looked lovely in my kitchen.

Both have a removable bean hopper that holds about 270 grams. It lifts off, so swapping to decaf in the evening takes seconds.

Both use the full depth of a standard 24-inch counter, so measure before you buy, especially if your counter is shallow.

Our tip: Leave a little room beside the KF7, because its water tank slides out sideways rather than lifting from the top.

Setup and the first week

Setup took about 15 minutes on both machines, and I didn’t need the manual once on the KF7. You fill the tank, set the water hardness, run a rinse and choose your first drink.

On the KF6, a coffee was ready about 40 seconds after I pressed start. The KF7 felt just as quick in daily use.

The first week told me a lot. On the KitchenAid KF6, I found the high-dose sweet spot within a couple of days, and from then on the espresso was dense and consistent.

On the KitchenAid KF7, week one was a honeymoon. The touchscreen and fridge-friendly milk container made it a pleasure to use, but I spent much of the week changing settings in search of a richer espresso.

Our tip: Order the milk container together with the KF6 if you drink any milk coffee, because it is not included in the box.

Screens, buttons and profiles

The KF6 uses a 2.4-inch color screen controlled with buttons. It is clear and responsive, but scrolling through 15 recipes with arrows is slower than tapping a picture.

The KF7’s 3.5-inch touchscreen is the nicest part of the machine. Drinks show as clear pictures, adjustments are a tap away, and strength is shown as bean icons.

Both keep four profiles, each with its own strength, body, temperature and size. In a two-person house, that ended the morning arguments about strength on both machines.

The KF7’s 3.5-inch touchscreen is a pleasure to use every morning.

Our tip: Set up a profile for each coffee drinker in the first week, because KitchenAid profiles save strength, body, temperature and size together.

How they brew

Under the skin, the two machines brew the same way. Water is heated by a thermocoil✕ThermocoilA heater where water flows through a coiled metal tube wrapped around a heating element. It warms water on demand and is ready quickly., pushed by a 15-bar pump through freshly ground coffee in a removable brew unit✕Brew unitThe part that compresses the ground coffee, holds it while water passes through and then ejects the used puck. A removable one can be rinsed under the tap., and the used puck drops into a drawer.

Before full pressure, each shot gets a short pre-infusion✕Pre-infusionA short, low-pressure soak of the ground coffee before full pressure starts, so the water flows through the puck evenly.. KitchenAid calls this setting body on the KF7, and on the KF6 it is an adjustable pre-infusion.

The pump is rated at 15 bar, but the coffee sees roughly 9 bar during a shot, the classic espresso target. Both grind with steel conical burrs✕Conical burrsTwo cone-shaped grinding parts, one inside the other. Beans are crushed between them, and the gap between the burrs sets how fine the coffee is. with 7 settings.

So why do they taste so different? In my testing, the KF6 simply used more coffee and extracted it more fully, and that made all the difference in the cup.

Our tip: Change one setting at a time on either machine, because strength, body and temperature all affect the cup and it is easy to lose track.

Grinder and dose

Both use steel conical burrs with 7 grind settings, adjusted next to the bean hopper. Seven steps is fewer than some machines offer, but it covered every medium and dark roast I tried.

The difference is in the dose✕DoseThe amount of ground coffee used for one drink, usually measured in grams. A bigger dose gives a stronger, fuller cup without simply adding bitterness.. On the KF6, the brew unit took about 12 to 14 grams per shot at the higher strength settings, which is generous for a one-touch machine.

On the KF7, strength is shown as bean icons, and even at the top setting the shot never had the KF6’s density. Changing the grind one step finer helped a little, but less than I expected.

So if you are choosing between them for coffee, the dose matters far more than the shared grinder.

Our tip: Turn the grind dial only while the grinder is running on either machine, because forcing it with the burrs stopped can jam beans.

Espresso quality

This is the heart of this comparison, and the gap is wide.

The KitchenAid KF6 pulled the most concentrated espresso I have measured from a one-touch machine. Shots of about 1.4 fluid ounces read around 5.5% TDS✕TDS (total dissolved solids)The share of the drink that is dissolved coffee. Higher numbers mean a stronger, more concentrated shot. Café espresso is often around 8 to 12%., and shorter shots reached 6 to 7%.

The crema✕CremaThe golden, foamy layer on top of a fresh espresso. It forms when pressure pushes oils and gases out of the coffee. was thick, mottled and stable for several minutes, and the body was dense and almost syrupy. The brew unit took about 12 to 14 grams per shot at the higher strength settings, which is generous for this kind of machine.

The KitchenAid KF7 often lacked richness, and its shots could turn bitter. Changing strength, body and grind helped less than I hoped, and it scored 6.8 for espresso against the KF6’s 9.0.

My espresso ratings

My scores out of 10 for body, crema, flavor and consistency.

The KF6’s crema was thick, mottled and stable for several minutes.

To be fair to the KF7, with the right beans its shots were drinkable, and in milk drinks the weakness mostly disappeared. My best drink on it combined a medium roast with whole milk: sweet, creamy and balanced, with none of the harshness of the straight shot.

Getting the best from the KF7’s espresso

I don’t want to overstate the KF7’s espresso problem. With the right approach, its shots were drinkable, and it is a lovely machine in every other way.

Here is what helped most during my four weeks, in order of impact.

My best drink on the KF7 combined a medium roast, a lighter body and whole milk. It was sweet, creamy and balanced, with none of the harshness of the straight shot.

Once you have found settings you like, leave them alone. Constant tweaking made the KF7 harder to understand, not better.

Our tip: Save your best KF7 latte settings in a profile once you find them, because its espresso is too sensitive to retune every morning.

How hot are the drinks?

On the KF6, my espresso read about 167 to 170°F in the cup, warm rather than piping hot. After about 20 minutes of use, the machine’s surface only reached 97 to 99°F, a sign of good insulation.

On the KF7, lattes sat comfortably above 149°F, and espresso on the high setting was as hot as I would want it.

On both, a cold ceramic cup cost about 5 degrees on a small shot. A quick rinse with hot water fixed it.

Our tip: Rinse your cup with hot water before every espresso, because a cold cup cost me about 5 degrees on both machines.

Milk drinks

Milk is the one area where the KF7 edges ahead, scoring 8.2 against the KF6’s 8.0.

The KitchenAid KF7 includes a milk container of about 790 ml with a sealed lid. It holds enough for four or five milk drinks, and it can sit in the fridge door all day and clip on when you need it.

The KitchenAid KF6 uses a hose with automatic frothing and rinsing, but you buy the container separately. Its foam was silky rather than thick, which suited flat whites more than tall, foamy cappuccinos.

One quirk on the KF6: cappuccinos always pour the milk first and the espresso second. The KF7 lets you change the milk and coffee order on supported drinks.

Both made genuinely good microfoam✕MicrofoamMilk foam with bubbles so small you can barely see them. It feels silky and glossy, which is what a good flat white or latte needs. with cold whole milk. My lattes on the KF7 sat comfortably above 149°F, a pleasant drinking temperature that keeps milk tasting sweet.

The KF7’s sealed milk container lives in the fridge and clips on in seconds.

Milk-drink ratings

My scores out of 10 for texture, temperature and ease.

Our tip: Use cold milk straight from the fridge on both machines, because warm milk makes big, loose bubbles that collapse in the cup.

Americanos and long coffee

For black coffee in a mug, the KF6 wins clearly. Its americano benefits from the concentrated espresso base, so even with plenty of water it never tasted thin.

The KF7’s americano carried the same thin, slightly bitter edge as its espresso. A medium roast and a lighter body setting helped, but it never matched the KF6.

Our tip: Keep the coffee part of your americano short and add more water, because a short, strong shot plus water tastes rounder than a long shot.

Two cups, guests and decaf

When friends come over, the two machines behave differently. The KitchenAid KF7 has a height-adjustable spout and makes two cups at once, which sped up a round of coffees noticeably.

The KitchenAid KF6 makes one drink at a time. For two people that was never a problem, but for six guests after dinner, I spent a little longer standing at the machine.

Both handle decaf well. You can lift off the 270-gram hopper and swap in decaf beans, or add a single scoop of pre-ground decaf through the chute.

For evening guests, I found the chute easier, because swapping the whole hopper leaves a little regular coffee in the grinder for the first cup.

Our tip: Use the pre-ground chute for a single decaf rather than swapping hoppers, because the first cup after a hopper swap still contains some regular coffee.

Cleaning and upkeep

Both are easy to keep clean. The removable brew unit rinses under the tap, and both machines rinse their milk systems automatically.

The KF7 scored 8.6 for cleaning and the KF6 8.4. The KF7’s sealed milk container and dishwasher-safe tray made daily cleaning a little quicker, though its drip tray was bulky to carry when full.

On the KF6, the full descale took about 45 minutes, most of it hands-off. The KF7 follows a similar guided routine.

Cleaning scores

My scores out of 10 from my single reviews.

Both machines have a removable brew unit you can rinse under the tap.

Our tip: Rinse the brew unit every week on either machine and let it air-dry overnight before sliding it back in.

Noise

Both are among the quietest automatic machines I have tested. The KF6 peaked just over 60 dB while grinding and sat around 55 to 56 dB while brewing.

Many automatic machines I have measured hit 68 to 71 dB, so the KF6 is gentle enough for a small apartment at 6 a.m. The KF7 was similarly quiet in daily use.

Grinding noise

KF6 measured with a sound meter in my kitchen.

Our tip: Keep the hopper lid on while grinding, because it muffles the grinder on both machines.

Beans, water and supplies

Both hold about 74 ounces of water and 270 grams of beans. In my house, that meant a water refill every two or three days and a fresh bag of beans every couple of weeks.

The removable hopper on both makes swapping to decaf quick, and both have a pre-ground chute for a single scoop.

Water tank and hopper, both machines

Identical on the KF6 and KF7.

Use filtered water if yours is hard. It keeps the thermocoil clean and means fewer descaling cycles, which take about 45 minutes on the KF6.

Our tip: Buy beans with a roast date on the bag and finish them within a few weeks, because both grinders show off fresh coffee far better than stale.

Long-term ownership

Both machines come with a 2-year limited warranty and share the same core parts, so their long-term care is almost identical.

The most important habit is rinsing the removable brew unit every week. Old coffee oils build up quickly, and a clean brew unit kept both machines tasting fresh through my four weeks.

Descaling comes around based on your water hardness. On the KF6, the full cycle took about 45 minutes, most of it hands-off, and filtered water stretched the interval.

On the milk side, the KF7’s sealed container needs a proper wash every couple of days, while the KF6’s hose rinses itself after each drink and needs a deeper clean weekly.

Neither machine showed any wear during testing, and the metal-clad bodies looked as good at the end of the month as on day one. That solid build is one of the best reasons to choose a KitchenAid at all.

Our tip: Mark your descaling date on a calendar, because a machine that is descaled on time brews hotter and tastes cleaner.

Four weeks with each

By the end of the month, I knew exactly who each machine was for.

The KitchenAid KF6 became my espresso machine. Once I had found the high-dose sweet spot, every shot was dense and consistent, and its quiet grinding meant I could make coffee before anyone else was up.

The KitchenAid KF7 became our latte machine. By week three, I had stopped making straight espresso on it, but the touchscreen, the milk container in the fridge door and the easy cleaning kept it in daily use.

Our tip: Try a straight espresso in the first week on either machine, because it tells you more about the coffee than any milk drink.

Who should skip both

If several people share your machine and everyone drinks something different, the KitchenAid KF8 may suit you better than either. It adds 40-plus drinks, six profiles, a plant-milk setting for oat lattes and two-cup milk drinks.

It also scored 8.6 for espresso, much closer to the KF6 than the KF7, so you don’t give up the coffee to get the features.

If you only ever drink black coffee, the KF6 is the one to buy, and you can skip the milk container entirely. If you only ever drink lattes and love the look of the KF7, it is still a lovely choice.

Our tip: Count the people who will use the machine every day before you choose, because three or more usually points to the KF8.

Real-life scenarios

Specs only go so far. These are the situations where one machine clearly pulled ahead during my testing.

For espresso lovers, the KF6 is the KitchenAid to own.

My scorecard

These are my own scores out of 10, taken from my single reviews of each machine.

KitchenAid KF6

KitchenAid KF7

Overall, I rate the KF6 8.5 and the KF7 7.6. The KF6 is the better coffee machine; the KF7 is the easier appliance.

Which one should you buy?

It comes down to one question: do you ever drink your coffee without milk? Still weighing other options? I rank every model I’ve tested in my guide to the best super-automatic espresso machines.

If you can stretch further, the KF6 vs KF7 vs KF8 comparison shows what the top model adds, and my KF6 vs KF8 head-to-head covers the two best KitchenAids.

For easy lattes and a lovely touchscreen, the KF7 earns its place.

How I tested and compared them

I used each machine as my everyday coffee maker for four weeks, making espresso, americanos, cappuccinos, lattes and cortados.

I weighed doses, measured TDS, measured espresso and milk temperatures with a probe, and measured grinding and brewing noise with a sound meter.

I followed every cleaning and descaling routine, then wrote up my notes and measurements together and compared them with KitchenAid’s specifications and owner documentation.

• Coffee: dose, strength, crema and temperature
• Milk: texture, temperature and container
• Workflow: controls, profiles and recipes
• Ownership: noise, cleaning and footprint
