If you really don't want to do wine, here are my favorites...
For raspberry lovers, try Chambord - it has a beautiful bottle. It is very good in sprite or 7 up, and also mixes into many other fruity drinks and gives them a nice flavor. It is great in margaritas.
I also love Amaretto or Frangelico (almond and hazelnut flavored, respectively) and they mix nicely with tonic or cream.
If your friend likes peppermint, Rumple Mintz is very good.
That's what I have tried and like!
