Do

Make sure you have well charged batteries for best resuts
Slowly warm your milk to 55-65°C (130°F- 150°F) for optimum sweetness and the best texture.
Use a narrow jug and ensure you have at least 40mm (1.5”) depth in the milk.
Start with the fine NanoScreen if it’s your first time, it’s a little bit easier.
Keep a steady hand and make very tiny movements and observe the reaction of the milk.
Start in the middle to aerate the milk in just 3-10 seconds. Listen to the gushing sound which means big bubbles are created.
Very slowly move towards the edge of the jug, make sure the NanoScreen is deep inside the milk and not near the surface. Now you no longer hear the gushing sound. Over time, the milk gets quieter and quieter as it is all turned into microfoam. Hold this position for 15 or until you feel the microfoam is homogenous.
Find the perfect position to keep a silent vortex in the milk. This pulls all the surface bubbles down.
A couple of practice attempts and a steady hand is all it takes.

Don’t

Don’t use cold milk if trying to create microfoam for latte art, it will end up too thick.
Don’t overheat the milk, it will taste burned and can leave marks in your jug.
Don’t start with too little milk, it is more challenging as big bubbles can easily form
Don’t raise the impelle

Question 2

Cleaning the NanoScreens

Accepted Answer

Best practices

Rinse and spin the NanoFoamer immediately after each use, either in a glass of water or directly under running water in the sink. This will prevent any milk from drying on the NanoScreen and the rotation will eject any residue.

Occasionally remove the NanoScreen and give it a scrub. We don't recommend removing the NanoScreen with each use as it may gradually loosen the fit.

Unclogging a NanoScreen

If your NanoScreen has become clogged with dry milk over time, take it off the impeller and soak it in lemon juice, or lemon and baking soda overnight. Then scrub with a stiff brush.

Get a fresh set

If your NanoScreens are clogged beyond repair and you feel it has become harder to create perfectly smooth microfoam, then maybe it is time to get a fresh set.

Question 4

Which AA batteries should I use?

Accepted Answer

What are the best batteries to use?

Using good batteries is important because the faster the NanoFoamer spins, the more power it has to pull surface floating bubbles down and then them into microfoam.

Rechargeable vs Alkaline

We like to use rechargeable batteries because it is more ecological but also because you'll always have a fresh set of batteries ready to switch out at a moment's notice.

Branded vs Supermarket or OEM batteries

We highly recommend not choosing generic supermarket brand batteries. This YouTuber has tested dozens of battery types and it is quite shocking how little power there is in some of the generic brands.

Alkaline vs Lithium

We have tested the AA lithium (non-rechargeable) batteries with the NanoFoamer and they do work really well. They output 1.5V of power vs 1.2V for Alkaline so the motor does get an extra boost from that higher power. We have not tested the rechargeable lithium batteries but they should also work just fine.

Question 5

What is the difference between the NanoFoamer V2 & Lithium?

Accepted Answer

Both units have the same design and components, as shown on our web page. The differences are:

The V2 is powered by two AA batteries (not included) and has a top speed of about 3,000 RPM
The Lithium is rechargeable via USB-C, powered by a 3.7V built-in Lithium-Ion battery, and has a two-speed option: 4,000 RPM and 3,000 RPM when fully charged.
