I bought a espresso machine for home. The machine I bought is a Ikohs Kaffeta.
It has a screwable piece that goes in the tip of the steam wand that it is used to create foam (as the manual says).
I see some other home espresso machines come with what it's called an auto-frothing wand, and basically is a piece that you can remove to make the wand work like a normal wand for creating more micro foam milk. I tried removing that piece but it only heats the liquid and creates a lot of bubbles. I can only put air into the milk and make a whirl using that piece. The thing is that I am tring to create more of a microfoam for trying latte art but I end up getting a thick layer of dense foam (which I also like) but I want to be able to create micro-foamy milk. I get nothing like elastic milk.
