Derby cheese is a mild, semi-firm cow's milk cheese with a smooth, mellow texture and buttery flavour. It has a pale, golden orange interior with a natural or waxed rind. It is quite similar in taste and texture to Cheddar and ripens at between one and six months. The most common variety available is the herb-flavored Derby that has the traditional light ivory/yellow colour with blended light green areas of herbs, such as Sage Derby.
