This is also my first encounter with Senbazuru from Sato Shuzo in Oita. It's a pure sake made from pure rice and a natural yeast.
This is a sake made from nature, without using lactic acid, which is produced from lactic acid bacteria in the air.
It is a sake made from the nature. It has a high alcohol content of 17 degrees because it is unpasteurized sake, but it is not heavy and you can enjoy it easily.
It is one of the best sake made with the traditional yeast mash.
