This raw milk Stilton is made to the old pre-1989 Colston Bassett recipe. So for customers who can remember how a good raw-milk stilton tasted back in the day, this is the one for you. A small sample of the Colston Bassett starter was revived after 18 years to produce this blue gem. Despite being the most authentic Stilton, Stichelton cannot be called Stilton because it is made from raw milk. Stichelton is how Stilton was spelled in the middle ages.
