Inoshishi
This is a special kind of sakè, the shop owner as soon as heard that I like strong and complex flavor suggested me this, and yess!
The first sip you can feel the sparkling, and... I don't know how to explain, a strong flavor, mix of Nama, and a strong acidity, but cut at the right point that doesn't annoy.
Then some minute after at the second sip, the effervence decrease, and here comes an evelopping sweetness with some acidity that you can feel only in your throat.
Awesome!!!
