I own Blue Cacao & Ginger - my thoughts:
The 'chocloate' note in this scent is IMO overwhelmed by the ginger, on my skin. Try it out on YOUR SKIN, before you buy a bottle. I LOVE ginger notes in scents, so I put up with this (FYI - sometimes the ginger note smells like nail polish remover, to my nose...)
In addition, the chocolate note in BCaG is NOT like the chocolate note in Borneo 1834 or the one in Yohji Homme...it's a more bitter 'herbal' chocolate note (is that the right word?). To be honest, I think I prefer the more 'hot chocolate' smell of the others.
I have three Jo Malone's - this one projects more sillage & has more longevity than the other 2. When I apply JM scents, I spray around 10-15 times to get them to last on my skin.
I wouldn't just wear this in colder weather...I wear it in the South Florida heat and it does ok.
As I said, not sure if I would START with BCaG...have you tried Pomegranate Noir (a Basenote fav')?
