Gin Finsbury. Finsbury Distilled London Dry Gin is one of the oldest of the gin brands that are known throughout the world. Finsbury Distillery was founded in London by Joseph Bishop way back in 1740. Ever since then, the name Finsbury Distilled London Dry Gin has been synonymous with the most stringent quality demands. This is not surprising, because even Bishop's forefathers were verifiably involved in the spirits business prior to 1740 and passed on a wealth of experience to the young entrepreneur.
