It is produced by Canada Dry Motts, a subsidiary of Keurig Dr Pepper.
The beverage is retailed in Canada's Maritime Provinces and northern areas in the state of Maine.
Dry ginger ale was developed during Prohibition when ginger ale was used as a mixer for alcoholic beverages, which made the stronger flavour of the golden variety undesirable.
Dry ginger ale quickly became more popular than golden, and today golden ginger ales like Sussex are an uncommon and usually regional drink.
The brand has had various owners, including Sussex Mineral Spring Co., Sussex Ginger Ale Ltd., Maritime Beverages Ltd., Great Pacific Industries Inc., Canadian 7up, and Crush Canada Inc. Sussex Golden Ginger Ale is now owned by Keurig Dr Pepper (formerly the Dr Pepper Snapple Group).
