I think if you love citrus but not sweet, Russian Caravan Tea is going to be a hit.
Personally, I don't love Christopher Brosius's take on the aquatics--I don't really smell the same "ocean" as he does, I guess. (See, e.g., Demeter Ocean and CBIHP Mr. Hulot's Holiday.) But the perfume that sent me on this whole odyssey is Demeter's Snow, which I find to smell exactly--EXACTLY--like the ozonic, crispy smell of snow when you eat it. Others don't, and that's clearly personal (see above re me and CB not agreeing when it comes to the ocean), but that's always made me think that Winter 1972 would be amazing.
As far as Black March, my understanding is that this is some sort of Wonka-esque blend of the clean-dirt notes from Demeter Dirt (which CB also formulated, I believe) and his clean-floral notes, a la To See A Flower, which I have a sample of, and find absolutely charming. Others have described it as like sticking your nose in a florist's refrigerator, and I agree. There's a lot of green, and a lot of FRESH flowers--nothing warm or heady. It's all very crispy. And it's my understanding that Black March has a lot of this Dirt note and a lot of the crisp floral of something like To See A Flower. (Apparently some of the Demeters also hit this crispy floral note--off the top of my head, I think it's Pruning Shears, Greenhouse, and/or Flower Show).
I know people love Burning Leaves, but I can't vouch for it personally. I like to limit my smoke, though, so it might not be up my alley anyway. Ambre Narguile is about as smoky as I get.
I have no frakkin' idea about Violet Empire.
My next CB is probably going to be one of: Tea/Rose, Wild Hunt, November, Cradle of Light (I looove a jasmine minus the indoles, like a really fresh jasmine, which is why I love L'Artisan The Pour Un Ete, since jasmine tea is like jasmine without the indoles), or Lavender Tea.
