Hi Ilario, I've never tried it but I assume it's not a problem as the consistency is similar. I once wrote a blog about milk substitutes, oat milk foams best, but almond milk doesn't work so well. I hope I could be of some help. Greetings Sandra

Hello Ilario. I use milk. For the use of other products, it is best to ask De Longhi directly. Greetings Marzio.
