Hi to all. I recently made a few batches of e juice using The Flavour Apprentice Bourbon concentrate. I mixed it with some Flavour Art cola and some TFA RY4 double. Thing is, after 3 weeks steep it tastes nothing like Bourbon at all. I mixed it at 5% and tried 10% but either way it actually tastes like some weird grape flavoured lolly! In fact with the RY4D there is that grape taste but at the very end i get an almost "mushroom" taste. Totally revolting. Can bear it with the Cola, Cola Grape vape bit odd but not sickening but damn, the RY4D mix is bad. Not my Pg or Vg as from the same batch of those i did RY4D and FA Cola, good vape, a straight RY4D which is nice and a FA rum FA Brandy with etc etc. Its just the TFA Bourbon that is rubbish. Thought id ask here before i question my supplier as i have read that some concentrates from various makers are just junk and nothing like they are supposed to be. The flavour is not Kentucky Bourbon, just straight Bourbon. Cheers.
