Fraistone

What Fraistone smells like

Fraistone (IFF) is a tart, fresh, anisic fruity note reminiscent of apple, plum and strawberry, in IFF's description. Fraterworks adds a faint liquorice hint. Beside Fructone, its close relative, it reads brighter, tarter and greener. One user found two samples sold under the same number smelled very different, perhaps because of isomer content.
