As the name suggests, it is a sake specializing in "acidity" and has a refreshing taste with a sourness on the tongue.
The mouthfeel is light and the aftertaste is sharp.
The sour lactobacillus aroma gives the impression of being "peculiar", but I was surprised when I drank it! It is very easy to drink!
It has a refreshing taste like yogurt. As the description says, you can drink it on the rocks and gobble it up.
I liked it so much that I want to keep it on hand.
