What makes it so great? Well, according to the marketing a Chinese magazine ad:
It's not just Scotch that's put into wooden casks. There's also Pabst Blue Ribbon Beer 1844.
Many world-famous spirits
Are matured in precious wooden casks
Scotch whisky, French brandy, Bordeaux wine...
They all spend long days inside wooden casks.
You can't argue with that logic. Scotch is put in casks. PBR 1844 is put in casks. PBR must be as valuable as Scotch! QED.
In other news, hamsters and lions are pretty much the same thing because they're both found in cages.
It turns out it's not as stupid an idea as you'd think. Being rich is sort of a new thing in China, and those that happen to get rich don't have a long history of Rockefeller types or gangsta rappers to show them how to show it off, so they're still sort of figuring it out.
