We have wine and sherry as ingredients!

Since the german description of that wine-cooler clearly calls the wine by its name and makes no mention of it being non-alcoholic I dont think having alcohol for us to consume would be a huge problem?

Considering how alcohol is made, I'm not surprised that its not a cul-recipe - I know most of them arent excatly "realistic" in the way we prepare them within minutes but they're all things a chef would be able to cook or prepare. Wine and ale dont excatly match that description to me - even for the Chilled Red we dont actually make whatever beverage goes in there, we just put it on ice. (And the beverages the recipe calls for are juices - something one could make in a kitchen!)
