Caerphilly is a hard, crumbly white cheese that originated in the area around the town of Caerphilly, Wales. It is thought to have been created to provide food to the local coal miners. The Caerphilly of that period had a greater moisture content, and was made in local farms. At the start of the 20th century, competition for milk in the local area saw production reduce and Caerphilly production was gradually relocated to England.
