Shredded wheat is a breakfast cereal made from whole wheat. As of January 2010, it was available in three sizes: bite sized (¾×1 in), miniature (nearly half the size of the bite-sized pieces), and full size, which may be broken into small pieces before milk is added (many brands refer to these pieces as “biscuits” and show the biscuit count on the box). Both sizes are available in a frosted variety, which has one side coated with sugar and usually gelatin. Some manufacturers have produced “filled” versions of the bite-size cereal containing a raisin at the centre, or apricot, blueberry or cranberry filling.
In the United States, shredded wheat is most heavily advertised and marketed by Post Cereals, which acquired the product in 1993 through its parent company,Kraft Foods, buying it from its long-time producer Nabisco. Kellogg’s sells eight varieties of miniature, or bite-sized, shredded wheat cereal. Natural and organic manufacturer Barbara’s Bakery makes an all-natural version of shredded wheat. In the United Kingdom, the Shredded Wheat brand is owned by Cereal Partners, a Nestle/General Mills company, although there are many generic versions and variants by different names. It was first made in the US in 1893, while UK production began in 1926.
