Wuliangye brand baijiu
Wuliangye / Wulianye is a luxury brand, as I recall.
There's a small liquor shop on Mott just below Canal (two blocks below? Can't remember...) that has a good selection of Baijiu, Maotai, Shaoxing Wine, etc, well up into the $500+ range if you want to go that far (and if you do, you better email me 'coz I want a a taste!) - been a bit curious about some myself, though not speaking the language I'm a bit lost. Like most brandies, the higher cost generally signifies aging - though in some cases, since many of them are infused with medicinal herbs, the price could reflect the rarity of an ingredient as well.
I suspect to some degree there's diminishing returns on the aged ones, as they'd be aged in ceramic, which wouldn't impart anything to the final product like wood barrelling does. Still, my curiosity may eventually get the best of me and I'll find myself spending much more than I should on a random bottle just to find out...
