Creating a silky microfoam can be a challenging enterprise: Even with the higher end prosumer machines we sell, it is arguably the most difficult skill to learn and sometimes takes more practice (and patience!) than folks expect from the outset.
The technique involves infusing the right amount of air and steam at the right pace to ‘stretch’ the milk, ultimately resulting in that wet paint texture that can be used in latte art, if you’ve got the skillz. You rest the tip of the steam wand on the surface of the milk and ‘ride’ it as the milk is slowly expanding with tiny air bubbles and coming up to temperature via the machine’s steam. You’ve got to keep a steady roll going, the bubbles to a minimum and eventually you’ll submerge the wand completely once you’ve achieved the amount of foam you want and need to simply bring it up to temperature.
