I'm a tea drinker and try to drink coffee recently. I wonder that Italian make milk foam for caffe latte or cappuccino. Would anybody tell me why? Thanks!

Yes. I agree that the mixture of milk foam and coffee crema create one kind of wonderful mouthfeel.

Is it true that the film or the interface between milk and air bubble includes more proteins and creams than the milk liguid?
