This is not an ordinary Sake. It is brewed at the birth place of Japanese Sake. The first book of Sake brewing was written in 1355 or 1487. And apparently it was in 菩提研 奈良 nara, where first Sake's were brewed. Those Sake were brewed in one stage, today Sake is brewed in 3 stages.
Historians may tell you rice and rice wine making came from China around 200 BC, but Japan has taken rice wine making to a new level over the centuries. The name 'Sake' is actually a bit incorrect, it refers to all alcohols in Japanese. In Japan, it should be really called 日本酒 nihonshu.
A Re-birth I will call it.
8 Breweries came together and re-followed the foot steps of their ancestors and make this Sake. It has a very supprisingly high polish rate and extremmely low 日本酒度. Definitely something special! Very RARE sake!!
