St. Killian is one of the oldest Irish cheeses produced by Patrick and Juliet Berridge from the Carrigbyrne Farmhouse Cheese Company. It's been 30 years since the couple have been making brie-style cheeses at their 198-acre farm outside Adamstown, in Co Wexford. St. Killian's is a hexagonal-shaped mould-ripened Camembert-type cheese made with vegetable rennet. Handmade with a bloomy white rind, the 250g hexagonal is made using milk of pasteurised cow's milk from the Berridge’s mixed herd of Friesian, Jersey, Angus and Montbelliard breeds. Beneath the bloomy rind contains a very soft, cream-coloured paste with flavours and aroma of salted butter and button mushrooms. The cheese is mild when young but develops an aromatic, clean flavour and softens as it matures.
