Mon Las is a medium firm, blue veined cheese from the Isle of Anglesey off the north western tip of Wales. The farm and dairy business keeps a pedigree herd of Holstein Friesian cows which graze on lush pasture throughout spring and summer. Their milk travels just 30 metres from the milking parlour to the small modern dairy. Caws Rhyd y Delyn's cheeses are made from entirely natural ingredients and in addition they use vegetarian rennet, making their cheese suitable for vegetarians.
