yuryur
I bought it at a store called "Yugan-no-Sato" in Tawa, Sanuki City, while passing by. It seems to be sold only here (they use their own rice and brew it here, too), and is a very rare sake.
The yeast is very active, and according to the warning, "In some cases, as much as half of the sake may spill over. It can reach the ceiling with great force," so it takes about 20 minutes to fully open the bottle, letting off the gas little by little.
It has a very rice-grain texture, a sweet sake-like mouthfeel, and a strong acidity that seems peculiar, but the more you drink, the more delicious it becomes.
