I saw him yesterday, and he described it as "a sugar bourbon"; flavored with caramel. His bar did not stock it, but he pointed where I could buy a bottle if I wanted.
He also recommended a
baijiu liquor as something different. It's a type of whiskey but not like most whiskeys or bourbons available stateside. Not a sake or wine, but a clear liquor with subtle hints, like a fine tequila or vodka.
This is the top of the line for baijiu.
