The Heinz factory in Wigan, England, is the largest baked bean factory in the world. The factory was opened in 1959 and currently produces over 3 million cans each day. The beans are shipped from North America and rehydrated once they arrive at the factory. They are blended with a secret mixture of spices and tomato sauce. The ingredients are steamed inside of the can.
Over 2.5 million cans of Heinz Beanz are sold every day in the UK, making it one of the most popular foods in the country.
