Ever tried syphoning it out from the bottom of a glass jug using a dairy tube?
I believe this will work with cow's milk but not with goat's milk
That makes sense to me. Cows' milk is not homogenised, so the cream rises. Goats' milk, as I understand it, is naturally homogenised, so the cream does not rise to the top. But I have no personal experience of goats' milk, apart from drinking it
