Orange Port and Tonic Cocktail Recipe

Yes, you can substitute white port with dry vermouth or a light white wine, although the flavor profile will be different. Dry vermouth will add a herbal note, while white wine will provide a crisp taste, but may lack the sweetness of white port.

Leftover white port should be stored in the refrigerator and consumed within 3 to 4 weeks after opening. It is best to keep the bottle tightly sealed to maintain its flavors and freshness.

If you don't have tonic water, you can use club soda as an alternative. While club soda will add fizz, it lacks the distinct bitter flavor of tonic water, so you may want to add a splash of fresh lemon or grapefruit juice for a similar taste.
