It depends what you are talking about. I have not heard of 'acidic' or 'acid' milk. Sour milk is simply milk that has turned because it is no longer fresh - sour EMAIL REMOVED - Send PM to This User Instead. Kefir is fermented milk. http://en.wikipedia.org/wiki/Kefir.
There is also Soured milk - Wikipedia, the free encyclopedia
Context is always important; labelling is rarely important.
