The name was derived from Hattori Arashiyuki's haiku, "A single plum blossom, as warm as a single flower," with the hope that those who drink the sake will feel even just a little happiness.
Made from rice grown in Kujukuri. It has almost no acidity, and the sweetness is not "sweet" but not spicy either, so it is probably more on the sweet side. It is not too spicy, so I guess it is more on the sweet side.
The one in the middle (so it won't change)
Slightly pear aroma, as expected from Chiba? (The name is plum).
Gentle sweetness spreads slowly. However, there is a pungency that lingers afterwards.
