I thought the basis of gin was juniper berries, not elderberries (although you can make elderberry gin in the same way as sloe gin)

The "good stuff" is made with juniper berries. Gin can be made from whatever is around.

The traditional basis of gin is basic industrial alcohol. The berries are just the flavouring.
