I'm really just sharing my happiness but, also, this might help a noob DIYer which I still consider myself to be. I've been DIYn for about a year now and found everything I mixed lacking in something. I referred to it as a "bite." By that I don't just mean TH but a "feel" in the whole mouth. Its actually the kind of heat a smoke provides I guess. Early on I read that some nics tasted of pepper so I went chasing that. Then I read some vendors add pepper for TH so I made my own flavorings from various peppers. Nothing was working to duplicate that bite and mouth feel. I vape tobacco flavors and alternate throughout the day between those and menthol. I had Koolada but never used it. Why would I when I already used a menthol I liked? All I had ever heard about it was it has no taste and makes vapor cool. Menthol made mine cool enough. Then I was working with a tobacco flavor I didn't think would go well with menthol so used Koolada for the first time. BINGO! There's the bite and feel I've been missing... the feel and "heat" of pepper without the taste of it. I'm sooo happy now and ready to rework my recipes adding a bit of Koolada. Maybe its just me... dunno... but my first reaction to Koolada was a coolness but that passed and now it feels like heat. Myabe because I'm so used to menthol? Anyway, its a very COOL ingredient that I'm just lovin.
