Ryukyu Awamori Uminokuni Aged Sake 720mL Bottled on 2006.03.22. Made in 1996. Stored with care. Comes in a dedicated box. According to the Okinawa Prefectural Sake Brewers Cooperative, the stopper was changed to silicone from the 2004 bottling onwards, so the stopper is likely silicone. Please forgive us if it is cork, as we cannot confirm. Please understand and purchase accordingly. This is the last bottle of Uminokuni that we have in storage. Please let us know if you have a preferred delivery date and time. Awamori Aged Sake
