This heavily beamed distillery has been concocting gin since 1793, making it the oldest producer of the spirit in the world. The Royal Navy ferried it round the world in countless officers' messes and the brand was specified in the first recorded recipe for a dry martini in the 1930s. Tours thread past the stills and take in a tutored tasting before retiring to the beautiful, Grade II-listed cocktail bar for a complimentary G&T. You can book places online.
There are also longer 'Gin Conoisseur' (£20) and 'Master Distiller' tours if you're a real ginophile.
