I'm a fan of Hangsen's RY4 and it's becoming impossible for me to get it at this point without mixing it myself. I've tried using their RY4 Aroma flavor and I just cannot get it right or even near. I recently stumbled across their RY4 Essence and that works well. Anyone familiar with Hangsen products enough to tell me the difference their "Aroma Flavor" & "Essence"? My Google searches are going nowhere. The Essence is much darker so I'm curious if it is just a matter of concentration.
Not familiar with this case, but could it be a line for foodstuff? The flavourings we use for vaping should not contain sugars or syrups, coloring, oils or anything but a safe carrier (pg) and the flavor. I believe some brands offer these for baking and such, which makes sense as that's how many of them started out :)
