Okinawan Awamori, 30% alcohol, 600ml bottle. - Brand: Donan - Type: Awamori - Volume: 600ml - Alcohol Content: 30% Thank you for viewing. The cap seal indicates Ryukyu Awamori (Shochu Otsurui) and was produced between 1977-1983. This is rare, as it's from the Showa era of Donan and the Shochu Otsurui period. The liquor from Yonaguni during this era was not modernized and has the taste of the so-called "old Awamori." However, there's a significant difference depending on the maker of Donan, and when I drank something from a similar era, it tasted like soil, haha.
