There are specific notes of oil characteristic types which blend well with others, some are better off on their own, and others aren't made often because of the difficulty perhaps or knowledge required. Plant therapy's coffee has the base, mid's and surprisingly the high end of the sweet notes. The sweetness eventually disappears, but overall, last long for a coffee essence.
I have been buying alot from this website. Excellent quality always!
I've used this for years and it still makes me feel relaxed. They even gave me a free reed diffuser with my recent repeat purchase. Absolutely love the scent and will support all the way!
