Same in Belgium. You can usually find fresh milk in any supermarket's refrigerators, but UHT milk is much more common because it's much easier to keep at home. There is less waste. With fresh milk you have to go shopping every 2 or 3 days or you have to hurry to finish bottles before they go bad. I only drank fresh milk when I lived in the UK or Japan, but personally I don't think there is a big difference of taste. But I never drink milk alone, only with cereals, or for cooking (pancakes, pudding, etc.).
