Can't drink that much, so only has this much per day.
Artist's commentary
Hang in There, Kogasa-san 3875
It feels like the change starts from the instant you break the seal. Whether the taste improves or gets worse depends on the brand, so it's a major gamble when you first see it. Sanae-san and I drank a 4-pack of sake over the course of four days, so we enjoyed the changes in flavor as well. We'd immediately put the bottle in fridge after pouring some into a glass, of course.
