The effect of some manufacturing conditions on the development of flavour in Cheddar cheese

Organoleptic assessments by the NIRD panel of Cheddar cheeses made with Streptococcus cremoris NCDO 924 or 1986, either in enclosed vats excluding nonstarter flora or in open vats, showed that high viable starter populations in curd did not give stronger-flavoured cheese, but led to the development of bitterness. Cheeses made in open vats developed typical flavour more rapidly than those made in enclosed vats. Maturation temperature was the most important factor in determining the flavour intensity; cheese ripened at 13d?C for six months had stronger flavour than corresponding ones ripened at 6d?C for nine months, irrespective of the starter or vat used.
