South Korean Shine Muscat prices fall 71% as rapid expansion erodes premium
South Korean retail prices for Shine Muscat grapes have fallen about 71% in five years as rapid acreage expansion created excess supply. Growers are now reducing plantings and tightening quality standards after complaints about sweetness and premature harvesting.
Retail price drops below competing varieties
South Korea’s Shine Muscat market has lost much of the premium that once distinguished the grape from other varieties. According to Pinpoint News, the average retail price for a 2 kg pack of large Shine Muscat grapes stood at 11,791 won as of the 1st, down 20.3% from a year earlier. The price was also 49.3% below the normal level, calculated as the three-year average after excluding the highest and lowest prices recorded from 2021 through last year.
The longer-term decline is sharper. A comparable 2 kg pack sold for approximately 38,000 won five years ago, meaning the current price in the low 10,000-won range represents a fall of about 71%. Shine Muscat is now cheaper than some varieties that previously occupied lower-priced market segments.
Kyoho grapes were selling for 20,045 won per 2 kg, while Campbell Early grapes cost 7,819 won per kilogram, equivalent to 15,638 won for 2 kg. Shine Muscat, formerly marketed as a luxury grape, was therefore priced below Campbell Early. The comparison shows that the decline is not simply part of a uniform fall across the grape category.
Acreage doubled before growers began retreating
Rapid growth in supply is the main pressure on prices. Strong consumer demand and high returns encouraged growers to enter Shine Muscat production, expanding planted area from 2,913 hectares in 2020 to 6,307 hectares in 2024, according to the Korea Rural Economic Institute. The cultivated area more than doubled in four years.
Plantings have since passed their peak. Area fell approximately 7% from 2024 to 5,877 hectares last year and is estimated to decline another 11% to 5,228 hectares this year. Shine Muscat’s share of South Korea’s total grape acreage rose from 22.1% in 2020 to 43.1% in 2024, but is projected to fall to 38.1% this year. The reversal indicates that growers are beginning to reduce their dependence on a single variety.
The price collapse puts pressure on farms that entered the segment expecting premium returns. Lower selling prices translate directly into weaker margins once production and labor costs are considered. Consumers benefit from greater affordability, but persistent quality problems could reduce consumption even at lower prices.
Quality controls target sweetness and early harvesting
Oversupply has coincided with growing dissatisfaction over quality. As output increased, some growers reportedly harvested insufficiently ripened grapes to bring them to market earlier. In a Korea Rural Economic Institute consumer survey released in June, 37.5% of respondents who had purchased Shine Muscat said quality had deteriorated, while 24.4% said it had improved. Complaints focused mainly on grapes failing to deliver the sweetness associated with the variety.
The Korea Grape Association is encouraging farms to ship only Shine Muscat bunches weighing at least 700 g and measuring at least 18 degrees Brix. Fruit weighing less than 400 g or registering 15 degrees Brix or lower would be withheld from the market and discarded. The association is also subsidizing purchases of cuttings for other grape varieties. Together with falling acreage, these measures are intended to curb excess supply, restore consistency and rebuild the consumer confidence required for Shine Muscat to regain a meaningful premium.
