In France, they did not parteurize the milk. Cafe au lait had 2 pots. 1 of coffee and 1 of heated milk. Equal amounts from each pot were poured into the cup. The coffee with heated non-pasteurized milk was delicious. Full bodied flavor with sweetness yet no sugar.
Maybe that is why they prefer ultra pasteurized which also doesn’t need to be refrigerated. As long as it is heated, which is the norm in France. I prefer UHT personally since that usually means organic, in America at least.
Ummm... heating pasteurizes the milk.
