What is "borchester"

Borchester is a fictional town in the BBC Radio 4 radio series The Archers. It is the county town of the fictional county of Borsetshire. According to series tradition it is located 6 miles north-east of Ambridge in the Am Vale and is an historic market and wool town. These typically English country-town features are complemented by more modern additions, such as Underwoods (an upmarket department store), Jaxx bar, which was previously a café both managed by Kenton Archer, and Ambridge Organics, the shop run by Helen Archer, who also makes the Borsetshire Blue cheese sold in Underwoods.
