At least in France, goat milk is highly popular, same with sheep milk. We make so many cheese from it ! And we're not alone ! Plenty of cultures around the world make goat and sheep cheeses, they're delicious !
Other than that, I don't think anyone drink sheep (or goat) milk in France. I may be wrong, but I assume if anyone did that'd be pretty exceptional.
That being said, why am I commenting on camel milk articles when I should be finishing this program -.-
On a side note, I am going to go try some camel milk now. But this absolutely seems more like a fad then reality. I mean goats milk seems to have a solid market share (and I am a sucker for carrageenan free chocolate goats milk) but unless camel milk tastes like a fresh macaron, I don't know if I would go out of my way or pay a premium.
