I used to love those candy apples you would get at fairs and amusement parks when I was a kid. My parents used to rarely ever buy them for my brother and I because they could already see the dental bills waiting to happen.
A red delicious apple dipped in caramel and brown sugar is what this e-liquid tastes like. Apple is actually a very hard flavor to replicate, but they not only pulled it off, but combined it with the sweet taste of caramelized sugar, just like a fresh candy apple.
This and Grilled Pineapple were my favorites of the Z-liquid line.
