Shine Muscat
Overview
Shine Muscat is a green grape variety developed in 1988 by crossing 'Steuben' and 'Muscat of Alexandria' at the Nagano Prefecture Agricultural Experiment Station in Japan. It was registered as a variety in 2006 and is characterized by being edible with its skin, seedless, and having the distinctive aroma of Muscat grapes along with high sugar content. In South Korea, it began to be cultivated in earnest from the late 2000s, and is now called the "luxury grape" and is favored as a gift fruit.
Key Details
Origin and Development Process
Shine Muscat was created in 1988 at the agricultural experiment station in Nagano Prefecture, Japan, by crossing 'Akitsu-21' and 'Hakubi'. Variety registration was completed in Japan in 2006, and its initial name was 'Nagano Purple' before finally being named 'Shine Muscat'. The goal of its development was to eliminate the astringent taste of the skin, a drawback of existing Muscat-type grapes, and to create a variety that is seedless, has excellent texture, and is easy to cultivate.
Characteristics of the Variety
Shine Muscat has the following outstanding characteristics.
- Edible with skin: The skin is thin and firm, with almost no astringency, so it can be washed and eaten immediately. This is a clear distinction from existing grapes.
- Seedless: It is naturally seedless, making it easy for children and the elderly to eat.
- High sugar content: It reaches 18–20 Brix, and because of low acidity, it is very sweet.
- Muscat aroma: It has the rich, luxurious aroma characteristic of Muscat-type grapes.
- Large berries: Each berry weighs more than 10 g, and the bunches are also heavy at 400–600 g.
- Long shelf life: It keeps longer than ordinary grapes, maintaining freshness for 2–3 weeks under refrigeration.
Cultivation and Production Process
Shine Muscat requires meticulous management during cultivation. Thinning work, or 'shot berry thinning', must be done thoroughly at regular intervals, and especially when cultivated for export in Japan, the number of berries per bunch is limited to 35–40 or fewer. In addition, a cultivation method of covering the bunches with bags to control light exposure so that coloring becomes uniform is common.
In South Korea, it is cultivated on a large scale in Gimcheon, North Gyeongsang Province; Geochang, South Gyeongsang Province; and Okcheon, North Chungcheong Province. In particular, Gimcheon is famous as a main producing area accounting for about 30% of the nation's Shine Muscat production. Since the 2020s, as vinyl greenhouse cultivation has expanded, the production season has been moved up, making fresh Shine Muscat available in the market even in summer.
Consumption and Cultural Position
Shine Muscat was initially classified as an expensive premium fruit, but as the cultivated area expanded, prices have gradually stabilized. Nevertheless, it remains one of the most popular items in holiday gift sets such as Chuseok or Seollal. Recently, it is sold in various forms from 1 kg small packages to large-capacity boxes in supermarkets and online malls, and it also frequently appears on café and dessert menus.
Latest Trends
From 2024 to 2025, several noteworthy trends have appeared in the Shine Muscat market. First, reflecting consumer concerns about pesticide residues and demand for eco-friendly cultivation, the share of pesticide-free or low-pesticide Shine Muscat is increasing. Second, Shine Muscat certified with GAP (Good Agricultural Practices) and low-carbon certification is being emphasized in premium channels. Third, exports to the Japanese market are becoming active, and exports to Southeast Asian countries are also gradually increasing. In addition, year-round production systems incorporating smart farms are being tested, centered on new suitable cultivation areas such as South Jeolla Province and Gangwon Province. These changes are moving toward providing safer and fresher products to consumers while strengthening the global competitiveness of Korean Shine Muscat.
