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.
