goats milk is closer to human milk. Secondly, goats milk does not have to be homogenised.
Homogenisation is about stopping the fat from separating with the rest. I'm not sure there is any nutritional benefit to unhomogenised, its probably more of a taste thing.
The big question is pasteurised or unpasteurised, but really unpasteurised milk is another way of raw milk. Good luck finding that.
Organic is probably better, but what really matters is whether they are grass fed or not. Another thing to consider is whether the milk is A1 or A2, but I don't know how it works in the UK.
