My Favorite Miso to-date

This is an empty container of my favorite miso.  I love it because it has this uniquely buttery aroma to it.  It is slightly sweet and the coarsely-ground soybeans in this miso also add a wonderful layer of nuttiness and bite to the paste.  I bought this package from the Mitsuwa Japanese grocery market in Edgewater, New Jersey.  Anyone with any idea on the background or written quality of this miso?
