With MF Guava I added 4 drops to a 16oz mug. So 2 drops per 8oz. It could have used another drop or two.May I ask, how many drops of flavor per 8oz of water.
It all depends on the flavor and whose it is. I also did FA Strawberry (Red Touch) and added 6 drops per 8oz / 12 in my 16oz mug.
Funny, just like with DIY I always start low and add more if I feel it needs more flavor.
And what the heck, we have all these flavors, might as well whip up some decent tasting flavored water.
