This is the only heated sake from Kaze no Mori, designed to be enjoyed as a heated sake, with the flavor changing at different temperatures. Kozanzake is an old sake that has been aged slowly over 10 years. The calm aroma gives off a peaceful atmosphere. The mouthfeel is very smooth, and the taste spreads from there with a relaxed, mild sweetness, acidity, and deep umami. The refreshing acidity that accompanies the dense and deep umami from the old sake is a perfect match, achieving both a profound and easy drinking experience. The lingering aftertaste that lingers long after swallowing is irresistible. Warm it to the desired temperature using the temperature sticker provided, and drink it in a bowl or a guinomi(a small sake cup) instead of a glass. Enjoy a relaxing moment.
