YU
It is also known as "Yukiten".
It is so fizzy that if it is stored on its side, half of it will blow out in one night.
It has the fruity taste typical of Amami, but with a heavy sweetness that is typical of dark nigori and a strong carbonation that lightens it up.
This is a very limited edition sake that sells out quickly and is only available during this time of winter.
