It is said to be the only apple in which, when shaken, the pips make a rattling sound as they are only loosely held i the apple flesh, whereas other apples have their pips contained as part of the apple flesh.
According to the Institute of Food Research , Cox's Orange Pippin accounts for over 50% of the UK area of dessert apples. It is virtually unknown in the U.S. market.
Cox is highly regarded because of its excellent flavour, and often thought as the best flavoured apple. The flavour and texture of the variety changes from complex acidic and crunchy in early September to more mellow and softer after storage. However it can be difficult to grow in many environments and tends to be susceptible to diseases. As a result, apple breeders have hybridized Cox with other varieties to improve yield without too much loss of flavour.
