No, Muslims generally cannot eat wine gums, specifically those from brands like Maynards.
While other gelatin-based sweets from brands like Maynards may be halal (permissible), wine gums are usually not. This is because traditional wine gums often contain gelatin that is not derived from halal sources. Halal gelatin must come from animals slaughtered according to Islamic law, or from non-animal sources. Given the usual composition, it is best to avoid wine gums unless specifically certified as halal. Always check the ingredient list and look for a halal certification.
