It's definitely water. This.
The dryness that complements the food also
It brings out the day. The kind that doesn't seem to get in the way, but is firmly "here".
It is a strange blended sake.
It reminds me of my experience at a restaurant called Marushin. The balance of sweetness and sourness is my favorite. The taste changes depending on the temperature of the wine glass and the palm of your hand. What can I say?
