Port Salut is a semi-soft pasteurised cow's milk cheese from Pays de la Loire, France, with a distinctive orange rind and a mild flavour. The cheese is produced in wheels approximately 23 cm (9 inches) in diameter, weighing approximately 2 kg (4.4 lb).
Though Port Salut has a mild flavour, it sometimes has a strong smell because it is a mature cheese. The smell increases the longer the cheese is kept — this however does not affect its flavour. It can be refrigerated and is best eaten within two weeks of opening.
The cheese was developed by Trappist monks during the 19th century at Port-du-Salut Abbey in Entrammes. The monks, many of whom had left France during the French revolution of 1789, learned cheese-making skills to support themselves abroad, and brought those skills back upon their return after the Bourbon Restoration. The name of their society, "Société Anonyme des Fermiers Réunis" (S.A.F.R.), later became their registered trademark, and is still printed on the wheels of Port Salut cheese.
