Difference between steam wand and aeroccino frother I often use an Aeroccino automatic milk frother that comes with some Nespresso machines. It froths milk by whisking it rapidly in a heated cup and produces a rather pleasant foam, though the resulting taste and texture is noticeably different from what I usually get at commercial coffee places. 

I don't know whether it's mostly due to some difference in the froth or the fact that I'm not using actual espresso (I use either a Nespresso machine or an Aeropress depending on where I am at the moment). 

Anyway, the froth does seem different, but what is the difference, precisely?
Another difference is that the Aerocinno tends to produce firmer and longer-lasting froth compared to a wand. It's designed to provide a one-size-fits-all solution for consumers accustomed to automatic machines, whereas a milk wand requires more skill to use but allows for a lot more customization. Think of it like an automatic vs manual transmission. 

Note that the type of milk you use can also make a difference. Keep this in mind when comparing the two.
