You're in for some fun! A friend who is a winemaker recently started making professional non-alcoholic ('dry') cocktails using botanics: he drinks all day for work and decided with his wife that they would stop drinking at home but they loved having a g&t after work, so he had to come up with something new. While these aren't yet for sale I've been "helping" with the taste testing (enjoying them very much) and they can be very very satisfying.
