Think I read it needs some steeping. Mine is about 3 weeks old from delivery. Vaping at 0.7 on a Reo Mini with RM2.This is interesting, because I picked up a bottle at the latest JHB vape meet. And I am getting a real strong sorta chemical aftertaste. The initial flavour is spot on with the inhale though. Is there a steeping period required perhaps. Because at the moment I can't vape it at all.
