Glebe Brethan is a cow's cheese produced by the Tiernan family at their Glebe farm near Dunleer in Co Louth. It is the first sheep's cheese to be produced in Ireland. It is a thermophilic, artisan cheese made using unpasteurised Montbeliarde cow's milk. The cheese takes its name from Baothan or Brethan, the founder of the monastic settlement at Lannleire.
Glebe Brethan is a mellow cheese having fruity and creamy flavours when young. As it matures, the cheese becomes more aromatic with spicy, nutty flavours penetrating the paste. It is smooth, pale yellow in colour with occasional holes and crystallisation in older cheeses. The honey coloured to greyish beige rind emits a very earthy aroma. The cheese is hugely versatile and can be melted over a variety of dishes including fondue. It is available in 40 - 45kg wheels.
