I bought it at Ponshukan in Niigata Station, looking for something that does not look like Niigata. The sweet and sour taste is similar to a sweet white wine.
As the label says, it is enjoyable when heated.
Delicious acidity.
Even a body tired from the extreme heat can keep drinking it.
It has a refreshing aftertaste, perfect for oily foods and tastes great with them.
It has a strong acidity, but also has sweetness and bitterness, and is delicious as sake.
