Long Lost Perfume's version of this one's VERY nice on me! Rich, dark honey anchored in some spices and the flowers from a formal European garden. Not terribly long lasting, but lovely while it's there.
I had a sample of the original a long time ago, which I loved, and then spent years trying to find it again. It resurfaced at Long Lost Perfumes, but either my memory fails me or the formula has changed; the new version doesn't have the same depth. This is a spicy fragrance with woody and subtle floral undertones. Warm and somewhat heavy; better in cool weather.
Update Jan 12, 2011: You can find versions of the original Tuvache Tuvara on eBay (cologne and "skin perfume"); this is more like the Tuvara I remember -- a slight myrrh-like bitterness followed by layers of deep herbaceous/spicy goodness.
I also found Tuvache "Sumatra" in my eBay travels -- a slightly lighter, but still spicy, bewitching brew.
