OSSAU IRATY AOC. Beneath its hay-colored, mold-dappled rind, Ossau-Iraty reveals a smooth ivory paste. The semi-firm cheese has notes of toasted wheat, roasted nuts, fresh grass and wildflowers. Its aromas are pleasantly buttery and sweet. As it ages, the cheese’s texture changes, losing its creamy yield and developing calcium crystals that result in a wonderful subtle crunch.
