Junmai Daiginjo sake from Fukura Shuzo is stored in red wine casks for about one month.
Separate from the current Hoshitori series, a new Junmai Daiginjo-shu specially prepared for cask storage is used.
Junmai Daiginjo, which offers the full flavor of rice, is enhanced by the subtle astringency and acidity of red wine.
The coloring, aroma, and taste vary depending on the aging temperature and length of time.
Because it takes time to mature, only about 300 bottles can be shipped each month in limited quantities.
