This stuff is just makes overpriced sugar water.  If you want to pay $12 for a 2 lb bag of unnecessarily colored sugar, it's your prerogative.  But there's no trick and no more effort to making nectar:  cup granulated sugar (sucrose) to each cup of water.  Boil to retard fermentation. Cool before using. Store excess in fridge.  Voila.
