Can a handheld milk frother produce micro-foam? When steaming milk with a steam wand, many sources I've found say that the texturing stage of milk frothing can only be done before the milk reaches body temperature, hence why cooling milk and milk jugs is important, as it allows more time for this process.

As an handheld milk frother (such as Aerolatte) needs milk to be heated before it froths, is it possible to produce a good quality micro-foam?
It certainly won't compare to a steam wand, but yes you can totally get okay milk texture using one. In all honesty though, I've had better success using a french press. Heat milk via stove stop, put your milk into a clean french press, and push and pull the plunge repeatedly until your milk froths. It's not perfect - but good enough to pour some latte art.
