Dimetapp Allergy typically has a grape flavor. This taste is often described as sweet and somewhat medicinal, similar to other grape-flavored children's medications. The grape flavor is intended to make the medicine more palatable for children, although opinions on the taste can vary. Some may find it pleasant, while others might find it too artificial or strong.

It's important to note that Dimetapp Allergy is an over-the-counter medication and should not be used as an ingredient in cocktails or any other recreational beverage. Mixing medications with alcohol can be dangerous and lead to serious health risks, including liver damage, increased side effects, and dangerous interactions.
