I used to drink it chilled, but when it gets lukewarm, it has more depth, but I can also taste some miscellaneous flavors.
It is better to drink it chilled in a wine cooler.
This sake is named after Char, the Red Comet, a good rival of Mobile Suit Gundam.
Like Char's character, it is a thick, umazake-style sake, but it is a refreshing sake that quickly fades away.
