is a quality control and accreditation organization operated in the UK by an independent, nonprofit body called the Cask Marque Trust (CMT). The mission of the CMT is to maintain the standards of cask-conditioned beer poured in pubs and then reward accredited licensees with a plaque and other promotional material. The CMT logo consists of a silhouetted beer engine and the slogan “A sign of a great pint.” CMT was founded in the late 1990s, at a time when the quality of cask-conditioned beer was in decline in Britain. At the time, the CMT estimated that one in five pints was served at an improper temperature. A research team from four leading British breweries—Adnams, Marston’s, Morland, and Greene King—determined that the diminishing quality of the British pub experience was largely the result of the then-new wave of nitrogenated beers. Subsequently, a CMT team of 45 brewing industry and quality control professionals conducted unannounced inspections of cask-conditioned beers in pubs that subscribed to the CMT program. By the end of 2010, some 6,750 pubs had been accredited nationally. To start the accreditation process, a pub owner must first apply and pay a nominal fee. The applicant premises are inspected, once in each of two consecutive months. Once accredited, the pub is then inspected twice a year, once in the winter and once in the summer, for compliance with the CMT temperature, appearance, taste, and freshness standards during both the warm and the cool season. The CMT requires that cask beers must be between 10°C and 14°C (50°F and 57°F) in the glass and have the clarity, aroma, and flavor characteristics of the brand that is being poured. They may be served at a lower temperature only if the brewery designed the beer to be poured below the CMT temperature specifications. Lists of CMT-accredited pubs can be located on the Web. The organization has evolved from its roots and now sometimes audits the quality of noncask draught beers as well.
