Shine Muscat sells for less than Campbell Early after Korean growers more than doubled its acreage
South Korea's Shine Muscat grapes retail for 11,791 won a 2kg box, less than the 15,638 won for ordinary Campbell Early. After two years of cuts, 79% more of the variety is still planted than in 2020, so growers are adding sweetness rules for what they ship.

What happened
- At the same point five years ago a 2kg box of large-grade Shine Muscat sold for 38,000 won, a drop the report put at about 71%.
- Korea Rural Economic Institute data show Shine Muscat area rising every year, from 2,913 hectares in 2020 to a 6,307-hectare peak in 2024.
- In an institute survey released in June, 37.5% of Shine Muscat buyers said quality had worsened, against 24.4% who said it had improved.
- The Korea Grape Association plans to discard fruit lighter than 400 grams or at 15 brix and below so it never reaches the market.
- The association also subsidizes purchases of cuttings for other grape varieties to expand their cultivation.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- decision Growers who picked early to reach the market sooner now have to weigh that timing against the association's sweetness floor for shipped bunches.
- cost Every box discarded under the association's plan is revenue a grower gives up to support the price of the boxes that do ship.
- exposure The cuttings subsidy steers new planting into other grape varieties, exposing them to the kind of rapid acreage growth that came before Shine Muscat's price fall.
The two prices in the series from the Korea Agro-Fisheries & Food Trade Corporation (aT) imply a fall of 69%. 11,791 won is 31% of 38,000 [1], two points short of the reported figure. Either way the premium has gone, or rather it has turned into a discount: a box is now 25% cheaper than Campbell Early and 41% cheaper than Kyoho [2]. Working back from the reported changes, the same box sold for about 14,790 won a year ago [3], and the agency's normal-year benchmark is near 23,260 won [4].
Planted area rose 117% between 2020 and 2024 [5] and is now 17% below that peak [6]. This year's 11% reduction [6] came in the same year as a 20.3% price fall [1]. The Korea Rural Economic Institute counts hectares [5], and the tonnage reaching shops can move differently if yields per hectare change.
Dividing area by the variety's share of all grape acreage [7] gives an implied national vineyard of about 13,180 hectares in 2020, 14,630 in 2024 and 13,720 this year [7]. On those figures other varieties shrank by about 1,940 hectares while Shine Muscat added 3,394 [8]. Since 2024 the other varieties have regained only about 170 of the 1,079 hectares Shine Muscat gave up, so most land leaving Shine Muscat appears to be leaving grapes altogether [8].
Analysts cited in the report blame oversupply and slipping quality. More growers picked fruit before it fully ripened so they could reach the market earlier [8]. "Consumer complaints about Shine Muscat are concentrated mainly on sweetness," the Korea Rural Economic Institute said [10]. It wants early shipments of underripe grapes blocked and quality-control technology upgraded at regional distribution centers [11].
If supply sets the price, further area cuts will lift it whatever the sweetness. If quality sets it, the Korea Grape Association's banner standard of at least 700 grams and 18 brix for shipped bunches [12] would create a top grade that wins back some premium while discards thin the market [13]. The third possibility is that buyers have repriced the variety for good. I think quality is the bigger factor, because an 11% area cut bought no price support this year [1][6]. The counter-case is that output per hectare rose and hid the cut. If next autumn's large-grade price gets back above Campbell Early only after another deep area reduction, supply was the driver and this view is wrong.
The two grading lines leave a gap. A 500-gram bunch at 16 brix misses the shipping standard but is above the discard line [12][13]. The report does not say where that fruit goes, or who pays for the fruit that is destroyed. Meanwhile the association's subsidy program pays toward cuttings of other varieties [14].
What to watch
- Whether the Korea Grape Association turns its plan to discard fruit under 400 grams or at 15 brix and below into enforced practice, and who funds the destroyed fruit.
- The Korea Rural Economic Institute's next acreage estimate, and whether area under other grape varieties rises as the cuttings subsidy takes effect.
- Whether regional distribution centers adopt the institute's recommendation to block early shipments of underripe grapes before next season.
