The smell is wonderful! It's lightly sugared grapefruit. Fresh grapefruit, as though you pulled it off the tree, cut it open & poured on a packet of sugar.
The scent is subtle in the room, nicely diffusing.
My only complaint--the cork was hard to remove! There was a little wooden lid covering the cork, and I managed to separate the two. Oh well, the pieces of cork inside the bottle add a rustic flair ;)
