Distilled above an ancient underground water source, Highclere Castle Gin is produced in Englands oldest gin distillery in one of the oldest working copper gin stills dating back to the 1800s. The recipe was meticulously developed over two years, experimenting with botanicals grown on the Highclere estate.This careful selection of botanicals in the recipe contains essential oils; it is the extraction of these oils in the presence of alcohol that gives Highclere Castle Gin its uniquely smooth flavour.
