Made from apples
Further ingredients unknown
It seems Healeys are keeping tight-lipped on the ingredients that make this gin. One thing they do say is that it's made from scratch at the distillery, which implies that they are fermenting and distilling their own apples, creating their own base alcoholic liquid, and then re-distilling to create their gin. This is a very rare thing for a distillery to do and shows true heritage for the county.
