Short of (1) reading the barcode, which says, in interleaved 2 of 5, that Wm. Shakespeare was just a pseudonym for Francis Bacon, a.k.a., Frank Sinatra, or (2), taking an unused old coil and a similar newly arrived coil apart and checking for chipmunk fur... you might try a taste test. Take an old batch unused coil, and install in a tank, cleaned and refilled with a favorite juice. Do the same with one of the recently arrived coils. Same model tank, same juice. Vape.
You will either discover that they taste different, or that they taste the same.
If they taste the same, this will be because they have the same wick and liner material, or because cotton, just like alligator tail, rabbit, and so many other things, "taste like chicken".
In short, I dunno.
