If you bottle your own milk, would there be cream on top of it?

Yes, if you bottle your own milk, there will be cream on top of it. Milk that has been bottled straight from a cow has not been homogenized. Homogenization causes the fats in milk to become emulsified. Non-homogenized milk will feature fats that separate and float to the top. The fats in non-homogenized milk are cream.
