Korean Whisky and the Long Bet on Time

“The spirit we make today becomes whisky ten years from now,” reads a line on the website of Ki One, the Namyangju distillery founded in June 2020. That sentence is the business model. A distillery buys grain, fills casks, and pays for warehouse space years before a bottle earns anything, and it has to survive the wait.

Two large Korean drinks companies decided not to. Shinsegae L&B stopped its domestic whisky project in early 2024, saying it takes a relatively long time to reach a product and a profit. On July 24, 2025, Lotte Chilsung’s board ended its Jeju distillery project, citing difficulty finding a site and a whisky market that had stalled and begun to shrink. Meanwhile Kim Chang Soo, who opened a small distillery in Gimpo in 2020, opened a second, 12-billion-won plant in Andong on July 7, 2026.

The public record cannot say who will be right. It can show the terms of the bet: a market that has cooled since 2023, grain and casks that are mostly imported, a climate producers say matures spirit fast but takes more of it, and a tax that rises as a whisky gains value. This feature draws on customs and farm statistics, statutes, and published reporting; it does not report a distillery visit or an interview.

Imports peaked in 2023

Korea’s whisky boom shows up in its customs records. Imports under HS 2208.30 were about 15,700 tonnes in 2021, jumped to 27,038 tonnes in 2022, and reached 30,586 tonnes in 2023, a record according to Customs figures reported at the time. They then fell to 27,441 tonnes in 2024 and 22,582 tonnes in 2025, down 26 percent from the peak.

Value fell less, from US$260 million to US$227 million, so the average declared value rose from about US$8.49 a kilogram to about US$10.04. Less whisky at higher prices is one reading; a different mix of products is another, and customs data cannot separate them. The United Kingdom supplied 81 percent of the 2025 weight.

For a new distillery this is the market its first bottles meet. Spirit casked in 2020 and 2021, as the boom began, is reaching a market that has since contracted.

A tax that grows with age

Since 2020 Korea has taxed beer and makgeolli by volume. Distilled spirits, whisky included, are still taxed on price: the Liquor Tax Act sets a 72 percent rate on the price at which the spirit leaves the distillery or is declared at import. An education tax of 30 percent of the liquor tax is added, and VAT after that.

A price-based tax falls hardest on the product that sits longest. Maturation “takes years and brings warehouse and inventory costs,” Newspim reported in June 2026, and “the more value ageing adds, the heavier the tax burden becomes.” A National Tax Service official told the paper that whisky and soju are grouped together as distilled spirits, which makes a separate regime for whisky hard.

Relief has come through the tax base instead. From 2024 the tax service let domestic producers deduct a standard sales ratio from the factory price before tax: 23.9 percent for whisky and 22 percent for soju. A National Tax Service notice of December 31, 2025 raised the whisky ratio to 28 percent from January 2026, and soju’s to 23.2 percent. On that basis, liquor tax and education tax together come to about 67 percent of the pre-tax factory price, down from about 71 percent at the 2024 ratio. That is Ag Digest’s arithmetic, before VAT.

Financing the wait

The law sets no minimum age. Korea’s statutory definition of whisky requires storage in wooden casks but no number of years, so a distillery chooses when to sell. Ki One’s first release, in September 2021, had spent just over a year in new oak. Kim Chang Soo released five young test bottlings before his first official whisky, “Gimpo,” in October 2024, a vatting of nine casks aged more than three years; KTX Magazine reported that its roughly 2,500 bottles sold out within a minute.

Capital is tied up in wood and space. A general whisky licence requires fermentation vessels of at least 5 kilolitres and at least 25 kilolitres of maturation casks and storage tanks. Since February 2025 a small-scale licence has allowed 1 to 5 kilolitres of fermenters and 5 to 25 kilolitres of casks and tanks for makers who ferment their own wash, which lowers the entry cost without shortening the wait.

How the wait is paid for is rarely public. Kim told KTX Magazine that he signed for his Gimpo building in July 2020 with his savings and borrowed money. Early releases, test bottlings, and small batches are one way to earn from a warehouse that is still maturing; whether they are enough is not something the public record shows.

What would make it an industry

The record supports a few conclusions. Whisky can be distilled and matured in Korea, at least two distilleries are selling it, and the rules have moved in their favour on licences, cask losses, and the tax base. Whisky imports, the clearest public measure of the market, have fallen since 2023, and the main inputs, malt and casks, still come from abroad.

What the record does not yet show is the evidence a buyer or lender would want: production and sales volumes, how much of each year’s spirit is lost in the warehouse, what domestic grain costs once malted, and how long it takes a distillery to pay back its casks. Until those numbers are public, Korean whisky is a bet that a fast climate can shorten a slow business.
