Subminimal
Cafe Quality Microfoam At Home
Producing velvety microfoamed milk in seconds, the NanoFoamer empowers better textured, better tasting, and better looking espresso based drinks.
Latte art may require some practice, but presents a fun challenge with extremely rewarding results. Simply choose your NanoScreen or flow controller, texture your milk as desired, and pour a heart, a rosetta, or perhaps something more abstract.
Interchangeable NanoScreens (superfine & fine)—or choice of flow controller and preset program with the NanoFoamer PRO—provide even greater control over the texture and density of your milk foaming, so you can get your flat white or cappuccino just the way you like it.
Featuring a comfortable, heat-resistant handle or silicone band, and a unique shape designed for utmost ease and precision of latte art pouring, the stovetop ready FlowTip Milk Jug is the perfect companion to the NanoFoamer.
Simply heat and foam your milk as desired to ready your pour: the smooth neck promotes a steady flow, with tangent edges that allow for wide ripples, and a sharp tip for fine details to finish your work of art... abstract or otherwise.

"It makes better quality foam than any comparable that I've tried- the only issue with the battery-powered version is that it seems to lose power gradually throughout the life of the battery, so you need to replace batteries often. But great foam."
"The good part: it makes excellently textured milk without introducing additional water compared to a traditional steam wand. Needs improvement: although the plastic impeller is a high quality plastic, it would have been nice to see less plastic. I also think that this should come with the wall mount as a standard accessory as it is awkward to store after use without it."
"I got the rechargeable Lithium version of the NanoFoamer, and this little frother creates excellent, silky microfoam once you get the technique right—possibly even better than my Breville Touch and Morning Dream! My tip: Hold it upright in the centre of the milk close to the surface for about 5–10 seconds for aeration, then tilt and lower it towards the side for the remainder of the time (another 10–15 seconds depending on power and volume of milk). Since it doesn’t heat the milk, you can take your time frothing without worrying about overheating it. You can also use the lower speed setting to start, and once you get the hang of it, the higher speed setting will froth the milk faster. I like to use the higher speed setting first, then switch to the lower speed setting near the end for more control. It comes with two nano-screens, although I’ve only ever needed the finer one. Battery life is excellent—I barely have to recharge it, and I appreciate having a battery level indicator. Cleaning is easy too—I just run it in some soapy water after each use and remove the nano-screen for a deeper clean every once in a while. The main downsides are having to heat the milk separately (remember to account for heat loss while frothing) and the lack of a power-button lock, which means it could accidentally turn on during travel. I wrap it in a cloth when I travel with it to prevent accidentally switching it on. Overall, a fantastic option for manual lever espresso machines without steam wands, or for travelling. I bring mine along with my K-Ultra and OXO Rapid Brewer! It’s also very reasonably priced for the quality of microfoam it produces, making it great value for money."
"Extremely fast delivery. Much faster than i expected. I thought for sure 7 business days but it took 2. Not even - delivered on a saturday from ordering mid day on a thursday. Definitely takes some skill but im using 1% lactose free milk so its already more watery, and the proteins more broken down. Pretty good results. If youre usinf 2% regular milk or a barista version of oat milk this is fantastic. I didnt spring the extra $30 for the lithium as, i dunno, didnt seem $30 justified the increase in RPM. If inreally want to, later ill get rechargeables on the cheap. I really dont think going from 2700rpm to 3500 was worth $30. It will do the job. Li batteries last about 3 years anyway so the thing wont last. I figured if i really liked it, for 50 bones its worth it and ill eventually upgrade to the pro, or whatever iteration is availble 3-4years from now."
"The Nanofoamer is not only good at foaming milk for latte pours, but also really good at mixing protein drinks. I use this every day to mix my protein drink, which my standard milk frother struggled with. I suspect if you drink powdered instant coffee or hot chocolate, this would make mixing a lot more convenient as well."
"Works really well. There’s a learning curve but once you get it, you won’t go back."
"Peut produire une mousse comparable à une machine à espresso professionnel.(Avec de la pratique)"
"Purchased the Lithium version back in Nov 2024. Work well for over a year with no complaints. Suddenly stopped working in Jan 2026. Contacted the brand (Nanofoamer) and discovered it had a one year warranty that just paased = They would not replace it. They suggested fixes, none of which worked. Then suggested that I buy a new battery that cost more than some foamers on Amazon. Disappointed - expected this to last much longer for the price compared to other comparable products. Would advice staying away from this."
"Despite having a slight learning curve, the NanoFoamer produces cafe quality microfoam."
"Makes nano foam as well if not better than expensive espresso machines (actually thinking of selling mine :) ) real nano foam, easy to make latte art, i got the lithium Nanofoamer it's definitely worth it !"
