Cheddar cheese
"Cheddaring" refers to an additional step in the production of Cheddar cheese where, after heating, the curd is kneaded with salt, cut into cubes to drain the whey, and then stacked and turned. Strong, extra-mature Cheddar, sometimes called vintage, needs to be matured for 15 months or more. The cheese is kept at a constant temperature, often requiring special facilities. As with other hard cheese varieties produced worldwide, caves provide an ideal environment for maturing cheese; still, today, some Cheddar cheese is matured in the caves at Wookey Hole and Cheddar Gorge. Additionally, some versions of Cheddar cheese are smoked.
