Here https://www.reddit.com/r/DIY_eJuice/comments/5gsf2m/dulling_out_of_flavorah_flavors/ I made a note that some Flavorah flavors dull out after some time. 4 days later, the red burley actually suddenly came out really, really strong (at 3,5%). The bourbon and honey are still gone, but hot damn, the burley hits fantastic like a strong, slightly ashy, nutty cigar.
So my two cents, leave the Flavorah bourbon and honey in the shop, the red burley is not bad at all.
Edit: So the steep of the whole concoction is 3,5 week
/u/baphomet assuming I spelled that right.. Maybe we should test this 3.5 week theory for Cured Tobacco too.
PS. OP, thanks for the update.
I'm eager to try it but have yet to pick any up... I will be picking up some PG sometime soon, so maybe then; still workin on the flavor shortlist, though... with x-mas looming, the wallets a little thin.
According to flavorah's website, they have designed their flavors specifically for ejuice. As part of that design, they have a faster steep. I don't know if that helps any or not, i have never used them. I was checking them out and came here to see what others think about them.
