Jazzy, it’s not quite like RY4 Double, because RY Dubs relies on flavor to mimic a tobacco taste, it comes off as dry, and I think the amount of Cyclotene in it comes off a little astringent, at least if I use it too much or too often. The HS Ry4 actually uses extracted tobacco (their claim) and it sure enough tastes like sweet tobacco leaves, dark caramel (very light) and a clean vanilla (not french, fruity, or dark). I never thought I would like actual tobacco flavors as I really didn’t ever enjoy smoking, and still don’t care for pipe, grassy, ashy, or overly dry tobacco. I don’t like a combustion taste either. It’s quite dessert-y and sweet, and works really well with sweet or nut flavors, vanilla, cream, ice-cream, you name it.
