"Aging is a process that cannot be rushed or easily simulated. There is no substitute for time. Quality conscious cheese makers never use additives, modified enzymes or artificial colouring. If mild cheddar lacks quality, it will never age well.
As cheddar slowly matures, like all other hard cheeses, it losers moisture and its texture becomes drier and more crumbly. Its naturally fresh and milky cheddar flavour is complemented by an increasing sharpness in taste, which is the result of high levels of acidity and salt. Sharpness becomes very noticeable at around 12 months (a k a old cheddar) and 18 months (a k a extra old cheddar) it overtakes the typical cheddar flavour.
The optimal aging period for cheddar varies between five and six tears. For most cheese enthusiasts three-year-old cheese is fine for general sue and five year old for special occasions. Regardless of age, however, the balance between flavour and sharpness is the ultimate goals of any cheese maker. "
