It is described as nigori (nigori sake), but it is really just a bit of ogara (a hint of ogara). The taste is generally as described on the label, and it is delicious.
The acidity is not as strong as other Eiko-Fuji wines. I thought it was best to drink it at a slightly warmer temperature, not at a very cold temperature.
Although it is labeled SPARK, the fizziness is very slight. Fruity and tasty, but quite robust. It is just right on the rocks in the summer. A chaser is also a must.
It's insanely good. It is in the same family as Roseyuki, but the water is different, and you can drink it forever. The alcohol content is low and just right.
It is said to be a concept worker series, but the contents are the usual Hiraizumi. It was sour and delicious. Despite the illustration, it was a solid drink.
