I am selling off my family's collection of sake. I enjoy aging my favorite sake, so this has aged since its production date. (It's ordinary sake, but it had gold leaf in it, so I might have forgotten to drink it and ended up storing it.) For those who appreciate aged sake and old liquor, and understand this, please consider purchasing. I cannot guarantee the quality.
