'''Cheddar cheese''' (or simply '''cheddar''') is a natural cheese that is relatively hard, off-white (or orange if colourings such as annatto are added), and sometimes sharp-tasting.

Cheddar is produced all over the world, and ''cheddar cheese'' has no Protected Designation of Origin (PDO). In 2007, the name West Country Farmhouse Cheddar was registered in the European Union and (after Brexit) the United Kingdom, defined as cheddar produced from local milk within Somerset, Dorset, Devon and Cornwall and manufactured using traditional methods.<ref>[https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/271260/pfn-west-country-farmhouse-cheddar.pdf "West Country Farmhouse Cheddar”], gov.uk.</ref><ref>Brown, Steve; Blackmon, Kate; and Cousins, Paul.

==History== [[File:MidSomerset Show 170803.jpg|thumb|Cheddar cheeses on display at the 2003 Mid-Somerset Show]] Cheddar cheese originates from the village of Cheddar in Somerset, southwest England.

The 19th-century Somerset dairyman Joseph Harding was central to the modernisation and standardisation of cheddar.<ref name="History"/> For his technical innovations, promotion of dairy hygiene, and volunteer dissemination of modern cheese-making techniques, Harding has been dubbed "the father of cheddar".<ref>{{Cite book|last=Heeley |first=Anne |author2=Mary Vidal |title=Joseph Harding, Cheddar Cheese-Maker |year=1996 |publisher=Friends of the Abbey Barn |location=Glastonbury }}</ref> Harding introduced new equipment to the process of cheese-making, including his "revolving breaker" for curd cutting; the revolving breaker saved much manual effort in the cheese-making process.<ref>''Transactions of the Royal Highland and Agricultural Society of Scotland'', Royal Highland and Agricultural Society of Scotland, 1866-7 volume 1, Aberdeen</ref><ref>Christabel Susan Lowry Orwin, Edith Holt Whetham, "History of British Agriculture, 1846–1914", ''Agriculture'' (1964), page 145</ref> The "Joseph Harding method" was the first modern system for cheddar production based upon scientific principles.

==Character== thumb|An unusual cheddar cheese that has been matured to produce veins of mould The ideal quality of the original Somerset cheddar was described by Joseph Harding in 1864 as "close and firm in texture, yet mellow in character or quality; it is rich with a tendency to melt in the mouth, the flavour full and fine, approaching to that of a hazelnut".<ref>''Transactions of the New-York State Agricultural Society for the Year 1864'', page 232, volume 14 1865, Albany</ref>
Cheddar made in the classical way tends to have a sharp, pungent flavour, often slightly earthy. The "sharpness" of cheddar is associated with the levels of bitter peptides in the cheese. This bitterness has been found to be significant to the overall perception of the aged cheddar flavour.<ref name="Karametsi 8034–41">{{cite journal |last=Karametsi |first=K. |date=13 August 2014 |title=Identification of bitter peptides in aged cheddar cheese. |journal=Journal of Agricultural and Food Chemistry |volume=62 |issue=32 |pages=8034–41 |doi=10.1021/jf5020654 |pmid=25075877 |bibcode=2014JAFC...62.8034K }}</ref> The texture is firm, with farmhouse traditional cheddar being slightly crumbly; it should also, if mature, contain large cheese crystals consisting of calcium lactate – often precipitated when matured for times longer than six months.<ref name="Phadungath">{{Cite thesis | last= Phadungath | first = Chanokphat| title = The Efficacy of Sodium Gluconate as a Calcium Lactate Crystal Inhibitor in Cheddar Cheese | url = http://purl.umn.edu/116278 | year = 2011 | publisher = University of Minnesota | access-date = 12 October 2013}}</ref>
Cheddar can be a deep to pale yellow (off-white) colour, or a yellow-orange colour when certain plant extracts are added, such as beet juice. One commonly used spice is annatto, extracted from seeds of the tropical achiote tree.
