NanoFoamer Instructions:

1.    Select a NanoScreen to suit your preferred microfoam type: Superfine, fine, or ordinary foam.

2.   Churn your warm milk (55°C is ideal) for about 15 seconds. Start in the middle to incorporate air, then move to the side to continue churning and blending the foam.

3.   Pour your perfectly microfoamed milk over espresso. It should feel like pouring paint. Draw a heart, rosetta or something abstract!




Changing the NanoScreens and adjusting how long you churn the milk adjusts the amount and density of microfoam you make.

  • For thin or less foam use the Super Fine NanoScreen and a quick churn.

  • For a medium amount or thickness of foam, use the Super Fine NanoScreen and churn for longer.

  • For a greater amount of foam, or thicker head of foam for drinks such as cappuccinos, use the Fine NanoScreen and churn for longer.


Note that the NanoFoamer can also be used without a NanoScreen to create normal foam or for mixing drinks.

IR thermometers measures the surface temperatures only, not the internal temperature of food or liquids or materials. Make sure you swirl or stir your milk before measuring for the most accurate reading.

IR thermometers can be temporarily affected by frost, moisture, dust, fog, smoke or other particles in the air. Be aware that steam, even when a liquid is not boiling, can condense on the thermometer and affect the accuracy of the measurements.

IR thermometers do not see through glass, liquids or other transparent surfaces, they measure the temperature of the first point of contact.

IR thermometers have a beam and measure on a spot, make sure this is properly aimed at the surface to measure and not reflecting off other materials like the sides of jug or pot.  Also, highly reflective surfaces like stainless steel tend to reflect ambient infrared energy rather than emit their own. So measuring boiling water in a highly polished stainless pot may give an incorrect reading.
