Cheese: Moulis Brebis

Went into the cheesemongers today and asked for some Ossau-Iraty (strange name but great stuff) to be told they were fresh out. It was suggested that I try Brebis de Moulis instead (34.50/kg), so I did and am enjoying it as I write. These are both fantastic sheep’s milk cheese (I’m having apostrophe angst – help! Klaus Klaus where are you?) with a nice nutty flavour. I’m wondering why these cheeses have such odd names, is it because they’re from the Pyrenees?
