After some time vaping The peppery taste is completely gone but the throat hit was a bit strong for my usual 18mg vape. I remixed my base to 14mg and it is now perfect. At 65vg/35pg/14mg delivers the perfect throat hit and no after taste what so ever. This base should produce a truer flavor. Funny thing is I would have expected a sweeter vaper from the heaver VG but the taste is a completely neutral taste.
Maybe you've just been vaping for quite awhile now and not experiencing it the same. I had a single puff of vape a few weeks ago that reminded me of how much I liked unflavored at the beginning. It's still good- just different now.
