The Muscat of Alexandria, commonly known as Muscat in Japan, is a grape with good taste and texture, but European grapes, including this species, are prone to cracking and disease in areas with heavy rainfall and are not suited to the Japanese climate, requiring facilities such as glasshouses for cultivation.
Resistant to disease and tolerant of the Japanese climate, American grapes are difficult to bite through and are generally considered to be less palatable than European grapes. It also has a unique aroma called foxy scent.
To improve on these shortcomings, the cultivar Steuben, which has the highest sugar content of all American grapes, and Muscat of Alexandria were crossed, and Grape Akitsu 21 was born.
This Akitsu 21 had a flesh similar to Muscat of Alexandria and was rather large, but it had a not-so-good aroma, a mixture of Muscat and Foxy scents.
Therefore, a large-grained European grape cultivar called "Hakunan" (a cross between Cattacurgan and Kaiji), which was created at the Uehara Grape Research Institute in Yamanashi Prefecture, was crossed with a variety that had the best quality and taste but gave up badly due to skin contamination, and this variety with only Muscat aroma was born.
The grapes were selected from the seedlings of a cross between Akitsu No. 21 and Hakunan in 1988, and from 1999 to 2002, the grapes were named "Grape Akitsu No. 23" and submitted to a strain adaptability test to examine their characteristics nationwide.
Named "Shine-Muscat" and registered on September 5, 2003, as Grape No. 21 of Agriculture and Forestry, and registered on March 9, 2006, as Grape No. 13,891 (valid for 30 years).
