sure wish we could get close to COV or MVB.....I love butterscotch.....but all DIY have failed miserably !!!!!
Somebody has to be able to do it ?... come on you guys are all flavor chemists
Butterscotch is my ADV, ever since I tried COV's juice.
I have it pretty close - I am sure that COV uses NF butterscotch 3x, as sure as I can be without having their recipe. When researching this project I saw a post stating (via rumor or otherwise) that COV uses absurdly high amounts of flavoring; there seems to be merit to this, as that was the biggest 'secret' I discovered when developing my vape. My 'scotch is mixed at 50% flavoring, a 50/50 mix of NF butterscotch 3x & NF butter rum, with a dash of EM.
It is 90% the same - I think COV has a hint of something else in it, possibly caramel cream or cake batter. I say cake batter because COV 'scotch turns pitch black after a month or two, & that is the only flavoring I know of that would do that to that degree, which would also blend into a 'scotch recipe so subtly.
As for MBV, who I have not tried, it does make sense for them to sell flavorings for their juice - if it is a blend of flavorings, mixed as 'butterscotch', then the consumer is still dependent on MBV for that flavor, whether it be juice or concentrate. Probably easier for them to sell straight concentrate than to mix up our individual preference of base & nic anyway.
NF/COV 'scotch does have trace amounts of diacetyl. That is why it is so good. Interestingly, NF just put up a bunch of 'diacetyl free' versions of some flavorings in their coffee/tea section, though butterscotch is not among them last I checked. Maybe soon.
