I was wondering why water is added to juice.  Sometimes I also see vodka.  Is it just to make it thinner?  Also, is water already added when you buy, say, a 36mg bottle of unflavored PG?  I'm just curious because I buy this higher mg unflavored pg and mix it with VG and add flavorings.  Do I still need to add water?
