of Gloucester cheese being called 'double' and 'single' is not known. The main theories are: because the creamy milk had to be skimmed twice to make the double variety, or because cream from the morning milk was added to the evening milk, or because a Double Gloucester cheese is typically twice the height. Cheese-rolling Double Gloucester cheese is also used every spring for the Cooper's Hill Cheese-Rolling and Wake, in which competitors chase a cheese down a steep Gloucestershire hillside; the first person to reach the bottom of the 50% gradient, slope wins the cheese.
