According the US legal code:
I'm not sure that there is a clear rule for the a general term for a fermented beverage with less than 7% ABV made from a fruit other than apples, such as hard lemonade or hard ginger ale. If they are at least 7% ABV, then in the US they are legally "wine."
If I am reading this article correctly, it sounds like in the EU only beverages made from fermented grapes can legally be sold as "wine." European Union wine regulations - Wikipedia
Maybe someone in the EU can shed some light on this.
Of course, since making it for your own consumption you can call it anything you want.
