From the Department Of Probably Useless Information: Duchy Originals organic milk from Waitrose is pasteurised but not homogenised.

Before our next-door neighbour farmer gave up his dairy herd at the time of the foot and mouth disaster, we helped ourselves to a gallon of his raw milk from the bulk container three times a week (we paid him). We allowed the cream to rise, skimmed it off and put it in our slow cooker overnight. Result? Skimmed milk (more or less), as fresh as can be, and more clotted cream than we could ever eat. All lovely stuff, and in over ten years we never picked up a single tummy bug.
