I am currently on 3 juices that I have on trial for the work day (2 KFL with about 3 ml each), and plan on writing a review for tonight.  I have 10 juices on my desk that I need to give a spin over the next 3ish days.  At last glance I have (70) 10-15ml bottles that I've never even tasted, steeped, almost ready for trial.  I like to tell people I don't even know what the 4th ml of any juice tastes like.  But that's not even true.  I try to keep about 3 loaded at all times to make sure my pallet is still on point. 
  
To complicate matters further, I constantly retest flavors to make sure my numbers are correct.  So to say that my rotation is somewhere near fifty juices would be about accurate.
