Diffuser Adaptability Please note: This 15 ml is only compatible with the Micro or Element Diffusers. Will not screw into Smart Diffusers. The Creation An explosion of citrus notes with orange playing the central role between zests and leaves, lemon, mandarin, mint and blackcurrant bud. Fresh, comfortable, sweet and zesty. The Inspiration"My grandmother used to love oranges. She would bake an orange tart, using fresh citrus from her thriving tree. Her tart base would have fine orange zest, and she would romantically stir freshly squeezed juice into the filling. The fragrance of the tart would stroll down the hall and tap on the spare bedroom door, begging for introduction. A fraction of waste was never allowed, my grandmother vowed, and so the orange tart would evince. I try to make the tart every few months, but I digress, as it would never compare. The only thing I manage to emulate is the fresh zest that envelopes the air."
