Apple cider varies in sweetness from brand to brand, so taste the finished drink before adding any extra sweetener. The combination of cider and ginger ale is usually sweet enough on its own. For the freshest flavor and best carbonation, assemble the cocktail immediately before serving.
If your cider is very sweet, choose a drier ginger ale or ginger beer. If your cider is tart, a regular ginger ale can provide a pleasant balance.
