Kizakura "Piano" is light and airy. It is wonderfully subtle, simple, and clean. This is a flavor profile of Japanese beverages that I adore, but which doesn't seem to have as much resonance within the US sake market. (Japanese wines, which have yet to do well at all in Western markets, remind of Kizakura's Piano.) This sake is a reminder of the "notes you don't play that count the most." 

On the nose, first, is a mix of both fresh and dried cherries. Then comes in scents of fresh-baked banana muffins, lemon custard, and lemon zest. Notes of grape come through as well. On the palate, this sake is wonderfully light. It seems to float around, without ever touching the ground. That's not to say that it lacks substance, but that it defies gravity. Based on measurements, we should say that it is medium-sweet, but through all the textural lightness, it doesn't read like a sweet beverage. It reads more like a flavored seltzer. (White Claw fans seeking an upgrade, take note.) Piano shows flavors of lemon, satsuma mandarin, yogurt, and rice. The liquid texture is like spring water. 

This sake practically yells out in a whispered hush, "STFU."

Piano, by Kizakura, is a naturally sparkling sake, which is made bubbly by fermentation rather than mechanical processes. 

Kizakura is a multi-disciplinary brewery who brews a number of sparkling sakes, traditional styles, and a whole range of craft beers as well.
