I had been a caramel addict until I found my previous flavoring (NF's Organic Caramel) probably contains diacetyl, which I MUST avoid due to COPD lung problems. Have been on a caramel hunt (11 others) since then and found nothing close to that yummy goodness I so miss, until.....
Dawn supplied best alternative(s) I've found so far but I need to confirm there is no diacetyl in these (fingers crossed). I now have your e-liquid Caramel and Caramel Popcorn Balls, plus flavorings Caramel and Expert Caramel which are steeping in mixes now. I am really hoping you can confirm these as diacetyl-free (PM me if needed). If not, they are probably fully safe for most folks but I'll have to resume my search.
Your Caramel and Caramel Popcorn Balls juices are quite good (and I just put in bigger orders). The Caramel is a bit weak for my taste so I re-ordered with 2X flavor. I do love the CPB juice as the corn boosts the flavor nicely! I wish it had a bit more vapor (more PG?) but the taste is truly great. (Any recipe hints, would love to customize)
I also HIGHLY recommend your Holy Vanilla flavor to all! I also had sampled many vanilla juices and flavorings and this is clearly the best I've found so far. I am very happy with the DIY Flavor Shack products I've tried and will be back again & again to sample many more.
