I agree that taste is subjective-
I agree that 99% of us are experiencing changing taste as our taste buds recover-
I agree that different people like different taste-
I agree that many people have favorite brands for flavors-
Most e-juices composition has nothing to do with the actual composition of the flavors they are supposed to represent. They are chemicals that are mixed to trigger the proper receptors in our taste buds to make us think we are tasting a particular flavor.
What I don't understand is the extreme variance in correlation for one flavor between 2 or more people. If I hand someone an e-juice that is supposed to taste like apple pie I would expect various responses; ie. "I can taste the apple but no cinnamon or pie crust", "I can taste cinnamon but no apple", "I can taste some of the flavors but I don't really like it". Not "Man that is nasty, are you sure that's apple pie". That's what confuses me, not that people have different taste, but that those differences can be so extreme with e-juices.
Now for everyone out there thinking,

" Dude, you are waaaaay over thinking this"

. My main concern in this is, over the last 3 months I have tried 30 some odd flavors and I have only found 2 that I can stick with. There have been others that I liked the flavor but they tended to change if i vaped them for more than 5 minutes or became dull after a couple of days and I loose interest. ( even with swapping out 3 or 4 flavors in 1 day ) I am worried that I can find a few flavors that I will be able to vape consistently with out them changing on me months down the road.
