I received an order from Nic River today, and got right to work creating my first ejuices using flavor combinations. I made three 30 ml sample batches. They turned out really great, like, better than any store bought juice I've tried. 'Blueberry Cheesecake' 4% (TFA) Blueberry Wild 3% (TFA) Blueberry Extra 2% (TFA) Cheescake 1% (TFA) Graham Crust 'Cherry Coke' 6% (TFA) Cola 1.5% (TFA) Raspberry .5% (TFA) Key Lime 'Juicy Fruit' 7% (TFA) Bubblegum Fruity 1% (TFA) Apple I haven't vaped them yet, still steeping, but I can tell from the smell they're spot on. I'm going to be making 500ml batches of these flavors, I'm nearly positive. Kind of a little bit proud of myself. Making ejuice is easy and fun for me, whereas finding out why a tank is shorting can take a couple hours sometimes. Anyways, onto the crux of the thread. The reason why I specifically chose The Flavor Apprentice over other brands was because they use terpenes in their concentrates and list them in the ingredients. I'd even attribute much of my success making ejuice recipes for the first time because I picked out flavors that contained terpenes. Each of those three recipes has at least one flavor that includes them. Technically, I think terpenes are categorized as artificial flavoring because they are not derived from the same ingredient that it's taste is emulating. I can imagine there exists a few reasons as to why flavor molecules created with real terpenes are superior, but it's more something I did out of curiosity. I was just wondering why more companies don't use them and advertise that they use them? It's a difficult subject to find much relevant information on because of it's association with the grey market. Are companies using them and not bother to advertise the fact because it's considered 'trade secrets'?
