Long time no post?
I like Niigata sake so much that I would have to close my eyes when I say "Niigata".
When you come to Niigata, please try Shigebari.
Kubota is a well-known brand of sake. Serve it chilled.
This cup is designed to change color in response to the temperature of the sake, and as it is poured, the color changes from the bottom, just like fireworks going off.
