Shropshire Blue is made from pasteurised cows' milk and uses vegetable rennet. The orange colour comes from the addition of annatto, a natural food colouring.  The cheese has a deep orange-brown, natural rind and is made in a similar way to Stilton. It is a semi-firm cheese with a sharp, strong flavour and a slightly tangy aroma. It is slightly sour but sharper than Stilton and generally creamier.
Shropshire Blue is produced in the UK by Long Clawson, Leicestershire and the Cropwell Bishop and Colston Bassett dairies in Nottinghamshire.
