This sake was made by isolating yeast from paulownia flowers at Tsukuba University!
Impression of a rather strong sake among ginjo-shu. Delicious!

Delicious!
I drank my first ginjo-shu a long time ago. It was on a business trip to Yonezawa at the end of the 20th century. It was a moment that changed my impression of sake.
