Collier's powerful cheddar is a tribute to the men who mined coal in South Wales during the 19th and 20th centuries. The miners were called colliers, and their work was hard and dangerous. For these men, cheese was a staple of their diet, and made for a welcome midday meal that sustained them underground.
Wales is one of the 4 countries within the United Kingdom and is situated at the western part of Great Britain. Wales has beautiful farmland, great for raising cattle, mountains, valleys, and rivers. The country's vegetation is mostly grasslands and forests, but the rugged Cambrian mountains dominate the northern part of the country.
The use of the word 'powerful' reflects the miners, but may also indicate the flavor of the 16 months aged cheddar cheese.
