Cratloe Hills Sheep's Cheese is an Irish cheese produced by Sean and Deirdre Fitzgerald at their farm in Brickhill, Co. Clare since 1988. It is the first sheep's cheese to be produced in Ireland. Their hard cheese us made using vegetarian rennet and pasteurised sheep's milk sourced from their own flock of Friesland ewes, which graze, on pastureland on the Cratloe Hills.
