Cortado. Caffe Latte. Caccionis. Affogato. Hot Wet. Flat White.
Two of those six drinks are fake, but that shouldn’t stop you from ordering one and expecting the barista to nod politely and whip something on the fly to avoid coming off as behind the times. Cafés in touristy regions of Italy began adding milk to coffee to make it more palatable for normies more than three centuries ago, and simple lattes and cappuccinos have been staples at American coffee shops since the late ’80s. Yet the obsession with tinkering and renaming subtle variations on this winning formula scans as a very third-wave development that feels less like innovation and more like beleaguered “riffing” for riffing’s sake.
The market for electric milk frothers is abuzz. A mechanized pitcher that automatically heats and froths milk is not a new concept, but a recent spate of boutique options that claim they can create the type of microfoam needed to pour latte with little effort is an exciting development. To borrow an aphorism my local barista rattles off daily while pouring flawless rosettas without batting an eye, “Big if true!”
Across the span of a month, I tried out eight milk frothers to see whether any of them could turn a cup of whole milk into that silky smooth microfoam that glistens under the ceiling lights before you knock it on the counter, swish it around, and pour it over a shot of espresso. This turned out to be a near-impossible task, but a few pleasant surprises gave me hope that a milk frother may one day be an indispensable part of my at-home coffee kit. Nouveau riche cortado junkies won’t find much to love in this list, but Gen Xers who pine for the days of cozy second-wave shops that serve foam-heaped cappuccinos in soup bowls while an Ani DiFranco clone sings slam poetry in the corner will be absolutely stoked on almost every item here. Busy moms with a brood of cocoa-slurping kiddos will find a worthy addition to their Christmas list too, which is not nothing!

With each unit I used 8 ounces of organic whole milk that was pulled from the fridge at 45 degrees Fahrenheit. I did not test any nondairy milks because of the wild variance in fat and sugar content, viscosity, and availability of each. Besides, we’ll probably be done with the hip alternative milk of the hour by the time this is published, rendering my extensive testing with fair-trade bird-safe macadamia milk useless.
I followed the instructions or quick-start guides that materialized after shaking out the box, and aimed for “wet froth” or a “flat white” if the instructions explicitly offered a process oriented toward that outcome. I swooshed the milk around in the frothing pitcher to get a better sense of the froth texture, decanted it into a Brewista Precision Frothing pitcher, and attempted to pour an 8-ounce cappuccino with latte art. I did this three times with each frother and made note of the average time of its frothing cycle, the final temperature of the milk, and the consistency and texture of the frothed milk.

Best Overall
Subminimal NanoFoamer Pro
This sleek, black pitcher from Subminimal managed to pull off a hat trick of impressive attributes that made it a shoo-in for the best of the best. The aesthetic is simple and understated yet eye-catching and futuristic. The engineering is advanced yet approachable. And the froth produced by the NanoFoamer Pro is perfect for latte art straight out of the pitcher—no need to decant into a steaming pitcher unless you’re adhering to strict scientific guidelines like I was.
The NanoFoamer Pro has a unique frothing system that utilizes a lid-mounted impeller instead of one that’s mounted on the base of the pitcher, leaving a tiny gap in between for increased circulation. Select from a trio of rubber color-coded “flow controls” that stick to the inside of the pitcher with a magnet, with varying thicknesses that control how fast the milk sloshes around them when the unit is turned on. Once the unit is placed on its base it will “wake up,” then you press the black-and-white LED screen to select 1 through 5 for the aeration time.
The laminated quick-start guide suggested the black flow controller (the thickest of the three) and a setting of 2 for wetter froth and a moderate dose size–somewhere between a cappuccino and a latte, based on the icons shown in the guide. I followed the instructions, waited about 3 minutes, and the machine beeped at me and said “OK” on the LED screen. The instructions suggest keeping the pitcher on its base an extra minute or two after you see it say “OK” for a higher temp, but 140 degrees Fahrenheit was exactly what I saw aiming for, so I pulled it off and examined it right away. The result was a remarkably consistent froth that had just enough gradient between wet liquid at the bottom and smooth foam at the top that danced into my cup with a quick twist of the wrist.
The NanoFoamer Pro is now my go-to for velvety-smooth froth on cortados with espresso from the Casabrews 5700 Pro (7/10 WIRED Review), which can’t steam milk and dose espresso at once on account of having only one boiler. Its froth is a nice accent for shots brewed with an old-school stovetop espresso machine as well, which means a budding barista with a minimal budget can use it to get in some reps at home without shelling out hundreds or thousands of dollars for a proper espresso machine.

Dreo BaristaMaker
The Dreo BaristaMaker is the Honda Accord of milk frothers. It’s sophisticated and capable, but it’s not byzantine or fussy. It does exactly what it’s supposed to do, and it will do so in an uncomplicated manner that anyone can appreciate. The buttons are simple and predictable. With the exception of the interchangeable impeller tips, there’s little explanation needed to figure out how to use this thing right out of the box. I tried it out without reading the manual to see what would happen, and I got perfectly functional wet foam steamed to 130 degrees Fahrenheit with very little effort. It wasn’t the best, but it certainly wasn’t the worst.
After reviewing the instructions, I figured out I used the wrong impeller in my trial run, so I switched to the tip that looks like an airplane propeller and adjusted my dose of milk accordingly. With a 7.5-ounce minimum capacity, you’re much better off with a larger drink, like a flat white or traditional latte, than a smaller drink like a cappuccino or cortado. The 10-ounce max capacity makes this a flexible option that’s fine for steaming a larger batch of milk that needs heat but very little aeration. The Froth Mode panel on the left has buttons for milk type, e.g. dairy, oat, etc., and different foam options for latte, cappuccino, and so on. The right side has a speed control that’s adjusted to match the tip that’s installed, and the temperature button is adjustable from 130 to 170 degrees Fahrenheit, or cold if you don’t want any heat.
I poured in 8 ounces of whole milk, selected Hot Cappuccino with the Foam button, dialed in 140 degrees Fahrenheit for the temperature, and selected the speed setting that matched the impeller tip rather than the mesh disc. About three and a half minutes later I got a pitcher filled with smooth, wet froth that formed a ring around a clump of dry foam that floated freely at the top of the liquid. It blended together nicely in the steaming pitcher, and a decent attempt at a rose adorning my cappuccino was the final outcome. The 140-degree Fahrenheit setting consistently undershot the desired output temperature by about, so I’ve been setting it to 150 to account for this one strange quirk.
