KitchenAid fully automatic espresso machines compared: KF2 to KF8

KitchenAid KF2 vs KF3 vs KF6 vs KF7 vs KF8 at a glance

Head to head

The best result in each row is marked, based on my testing and KitchenAid’s specs. Where two machines tie, both are marked.

The tally is not my verdict. A family will weigh profiles and milk far more heavily than counter width.

How the KitchenAid range steps up

KitchenAid’s numbering looks like a straight ladder, but it isn’t. It’s really two bodies and three milk systems.

The KF2 and KF3 share a slim body about 7.7 inches wide. The KF6, KF7 and KF8 share a full-size body about 10.2 inches wide.

Within each body, the milk system is what you’re paying for: a manual steam wand on the KF2, a one-touch hose on the KF3 and KF6, and a container system on the KF7 and KF8.

The surprise in my testing was that the coffee itself doesn’t improve as you climb. The KF6 made the best espresso of the five, and the KF7 made the weakest.

So decide on the milk system and the screen you want first, then check the espresso scores before you pay for the top of the range.

Our tip: Choose your milk system first, because it decides more about your daily routine than any other spec in the KitchenAid range.

Design, size and build

All five look like KitchenAid appliances, with rounded edges and a choice of finishes on the bigger models. The KF7 and KF8 come in Stainless Steel, Porcelain White, Cast Iron Black and Juniper.

The slim KF2 and KF3 are remarkable on a crowded counter. At about 7.7 inches wide, 14.2 inches tall and 18.5 inches deep, they fit in gaps where most bean-to-cup machines simply won’t, and they weigh about 19.8 lb.

The full-size KF6, KF7 and KF8 measure about 10.2 inches wide, 14.3 inches tall and 18.6 inches deep, and weigh 28 to 29 lb. The KF8 also needs room for its side milk container and overhead clearance, because its tank lifts out from the top.

The KF3 packs one-touch milk into a body under 8 inches wide.

Width on the counter

Measured without milk containers. The KF8’s side container adds noticeably more width.

The KF6 felt the most solid of the five, with a heavy, metal-clad body. The KF8 felt the most refined, and the KF7 the most thoughtfully laid out, with a tank that slides out sideways.

On the slim pair, the tank loads from the rear. It saves width, but you’ll want to leave a little room behind the machine or slide it forward to refill.

Our tip: Leave a few inches behind the KF2 or KF3, because their water tanks load from the rear.

Screens, controls and profiles

The controls change more than anything else as you move up the range.

The KF2 uses simple buttons for its three presets: espresso, coffee and over ice. There are no profiles, so everyone shares the same settings.

The KF3 adds a 2.4-inch color screen with touch controls and four profiles, and lets you tune strength, temperature, volume and body. The KF6 has the same size color screen but with buttons, plus four profiles.

The KF7 brings a 3.5-inch touchscreen with four profiles, and the KF8 a color touchscreen with six. On both, each person tapped their profile and got their drink without touching a setting.

User profiles

From each machine’s menu.

On the KF7 and KF8, you can also choose whether milk or coffee goes into the cup first on supported drinks. The KF6 always pours milk before the espresso on a cappuccino, which some people won’t mind and others will.

The KF8’s touchscreen keeps more than 40 drinks easy to find.

Our tip: Turn off the button beeps and shorten the standby timer on the first evening, so early mornings stay quiet.

Drink menus: from 3 presets to 40+

This is the steepest ladder in the range.

The KF2 has three coffee presets, plus hot water and steam from the wand. An americano means brewing an espresso and topping it up from the wand.

The KF3 adds one-touch cappuccino, caffè latte, latte macchiato, macchiato, americano, iced coffee, iced espresso and warm milk. The KF6 lists 15 drinks, including doubles, and the KF7 more than 20, including a cortado.

The KF8 lists more than 40, including ristretto, cortado, flat white, caffè olé, warm milk and frothed milk.

Drinks on the menu

Grinders and dose

All five grind with steel conical burrs✕Conical burrsTwo cone-shaped grinding parts, one inside the other. Beans are crushed between them, and the gap sets how fine the coffee is. and brew at up to 15 bar.

The KF2 uses KitchenAid’s IntelliGrind, which sets the grind automatically with a manual override, and doses roughly 7 to 15 grams across three strength levels. A 2× option runs two full grind-and-brew cycles.

The KF3 takes up to about 15 grams. The KF6 dosed about 12 to 14 grams in my testing, and the KF6, KF7 and KF8 all offer seven grind settings, with the KF8’s grinder insulated for noise.

On the full-size trio, the bean hopper lifts out, which makes swapping to decaf a one-minute job.

Our tip: Only change the grind setting while the grinder is running, because turning it with the burrs stopped can jam beans on any of these machines.

Espresso quality

This is where the range gets interesting, because price and espresso quality don’t line up.

The KF6 pulled some of the most concentrated espresso I’ve measured from a one-touch machine. The crema✕CremaThe golden, foamy layer on top of a fresh espresso, formed when pressure pushes oils and gases out of the coffee. was thick, mottled and stable for several minutes, and the shot was dense and well extracted.

The KF3 was close behind, strong and consistent with its 15-gram dose. The KF2 and KF8 both made smooth, well-made shots: the KF2 with a dense, hazelnut crema at strength three, and the KF8 with a balanced cup that wasn’t the most concentrated.

The KF7 was the disappointment. Its espresso was thin at first and often bitter later, and changing the settings did little for the flavor.

My espresso scores

My scores out of 10 for body, crema, flavor and consistency, same medium-dark beans.

The KF6’s espresso had the thickest, most stable crema of the five.

Milk systems: wand, hose or container

Milk is where these five machines really differ, and it should decide your shortlist.

KF2: a real steam wand

The KF2 keeps a Panarello-style steam wand✕Steam wandA metal pipe that blows steam into a jug of milk to heat and froth it. A Panarello-style wand has a sleeve that pulls in air for you, so it’s easier for beginners. with a slider for two foam settings. Plenty of simple wands only make big, soapy bubbles, but this one made silky milk, even with oat milk.

Every milk drink is up to you, though, and a latte takes practice and a couple of minutes.

KF3 and KF6: a one-touch hose

The KF3 and KF6 draw milk through a hose, froth it and add the espresso at one touch. The KF3’s dual milk delivery makes two milk drinks at a time. Its bubbles were fine, if slightly stiffer than a skilled hand gets from a wand.

On both, the milk container is sold separately, so you’ll drop the hose into your own jug or carton.

KF7 and KF8: a container system

The KF7 includes a 27-ounce milk container with a sealed lid that clicks on with a tube and goes straight back into the fridge. The KF8 uses a side container that keeps the drip tray clear for two cups, and adds a plant-milk setting that genuinely helps with oat milk.

The KF8 made the best milk drinks in KitchenAid’s range, with lattes finishing around 147 to 151°F.

The KF8’s side milk container keeps the drip tray clear for two cups.

My milk drink scores

My scores out of 10 for foam texture, temperature and convenience.

Our tip: Use cold milk straight from the fridge on every KitchenAid, because warm milk makes big, loose bubbles that collapse fast.

Drink temperature

Temperatures varied more across this range than I expected.

The KF6 was the hottest, with espresso around 167 to 170°F in the cup. The KF8 landed around 162 to 165°F in a warmed cup, and its lattes finished at a pleasant 147 to 151°F, right in the zone where research on cappuccino milk finds sweetness peaks.

The KF2 was the coolest. Its standard shots landed around 118 to 122°F in the cup, which is pleasant to sip straight away but cooler than most people expect.

Espresso temperature in the cup

Probe readings straight after brewing on the highest temperature setting. The KF3’s regular shots ran a few degrees above its iced shots at about 113–117°F.

Iced coffee

The slim pair are the only ones with iced presets. The KF2 has an over-ice mode, and the KF3 adds iced coffee and iced espresso.

Neither actually chills the coffee. On both, iced shots came out at about 113 to 117°F, only a few degrees below a normal shot, so they melt ice quickly.

My fix was the same on every machine: brew a strong, short shot over a glass full of large cubes, then top up with cold milk.

Our tip: Use large ice cubes for iced coffee on the KF2 or KF3, because their iced shots come out warm and melt small cubes in seconds.

Cleaning and upkeep

All five rinse themselves and prompt you for cleaning and descaling. The differences are in the milk side and how easy the parts are to reach.

The KF2’s wand is the simplest to clean: wipe it and purge it after each use. The hose machines, KF3 and KF6, flush hot water and steam through the hose after milk drinks, and the KF3’s hose needs that rinse after every single milk drink.

The KF7 scored best for cleaning. Its brew unit pulls out for rinsing, its drip tray is dishwasher-safe and its milk container goes straight into the fridge. On the KF8, I pulled the brew unit out through the right-hand panel every week and rinsed it under the tap.

My cleaning scores

My scores out of 10 for rinses, part access and daily effort.

Our tip: Rinse the KF3’s milk hose after every milk drink, not just at the end of the day, because it’s the step that keeps its foam consistent.

Noise

The full-size machines are the quiet ones.

The KF8 grinds so quietly that across a whole drink my meter averaged in the mid-40s dB, with short peaks while grinding. You hear the brew unit moving more than the grinder.

The KF6 peaked just over 60 dB while grinding and sat around 55 to 56 dB while brewing, gentle enough for a small apartment at 6 a.m.

The slim KF2 and KF3 measured about 70 dB grinding and 60 dB brewing. Because every 10 dB sounds roughly twice as loud, they sound about twice as loud as the KF6 while grinding.

Grinding noise I measured

Phone sound meter readings at about 20 inches.

The KF6 and KF8 are the machines to choose if someone is still asleep.

Capacity, beans and supplies

Capacity climbs with the body size. The KF2 and KF3 hold about 61 ounces of water, the KF6 and KF7 about 74 ounces and the KF8 about 84.5 ounces.

Hoppers are closer: about 8.8 ounces on the KF2, 9.3 on the KF3 and 9.5 on the full-size trio, where the hopper also lifts out.

Water tank size

Manufacturer capacities.

Use fresh whole beans within a few weeks of the roast date. Medium and medium-dark roasts suited every machine, and very oily beans are worth avoiding in any automatic grinder. Spent pucks are great for the compost.

Our tip: Swap to decaf by lifting out the hopper on the KF6, KF7 or KF8, or use the pre-ground chute on any of the five.

Mistakes to avoid with any KitchenAid

After five months of KitchenAid machines between us, the same few habits kept coming up. None of them are hard to fix, but each one quietly makes the coffee worse.

The most common is judging the espresso on the first day. Every one of these grinders needs a few cycles to settle, and the first cups after setup were weaker on all five. I didn’t score anything until the fourth drink.

The second is reaching for more water when a drink tastes weak. On every model, raising the strength or grinding finer fixed weak coffee far better than a longer pour, which only makes it thinner and more bitter.

The third is milk hygiene. Milk residue sours within a day, so on the hose machines the rinse after each milk session is not optional, and on the KF7 and KF8 the container belongs back in the fridge as soon as the drinks are made.

One more for the slim pair: their rear-loading tanks are easy to forget about until a drink stops halfway. On the KF3, I got into the habit of refilling the tank first thing every morning, before the first coffee.

And on the full-size machines, use the removable hopper. Lifting it out to swap beans or clean it takes under a minute, and stale oils in the hopper are an easy source of flat-tasting coffee.

Our tip: Test your water hardness with the included strip on day one, so the descaling reminders on any KitchenAid are accurate from the start.

Real-life scenarios

These are the moments where one machine clearly pulled ahead during my testing.

The KF7 is the easiest of the five to keep clean, but its espresso held it back.

My scorecard

These are my own overall scores out of 10, from four weeks with each machine. Each blends espresso, milk drinks, ease of use and cleaning.

Overall scores

My overall editorial scores.

The KF8 wins overall because it does almost everything well. The KF6 is the coffee lover’s pick, and the KF3 is the best value per inch of counter. The KF7’s easy living couldn’t make up for its espresso.

Which one should you buy?

Start with your counter, then your milk.

If you have less than 9 inches of width, it’s the KF2 or KF3, and the choice is steam wand or one-touch hose. If you have a normal gap, choose between the KF6 for espresso and the KF8 for everything else. For the wider picture beyond this matchup, see my guide to the best super-automatic espresso machines.

For most households, the KF8 is the KitchenAid to buy.

How I tested and compared them

I used each KitchenAid as my everyday coffee maker for four weeks, making espresso, coffee, americanos, cappuccinos, lattes, latte macchiatos and iced drinks, and steaming milk by hand on the KF2. A second HouseholdMe tester shared the machines, and we wrote the notes together.

I measured espresso and milk temperatures with a probe, noise with a phone meter at about 20 inches, and foamed whole, semi-skimmed and oat milk. I set up profiles, worked through grind and strength settings and ran every rinse, cleaning and descaling program.

I then checked my notes against KitchenAid’s specifications and owner documentation.

• Coffee: crema, body, flavor and consistency.
• Milk: foam, temperature and convenience.
• Workflow: screens, profiles and drink range.
• Ownership: cleaning, noise, capacity and footprint.
