Korean ramyun

The scariest noodle in Korea loses to a Korean pepper.

Korean instant noodles get sorted into “spicy” and “very spicy” by almost every English guide, which sends people to the wrong packet. The real differences are the soup base — chili, soybean paste, black bean — and whether there is broth at all. Here they are side by side, with the Scoville figures that have actually been published. For scale: a fresh cheongyang pepper (청양고추), the thing Korean cooks reach for when they want real heat, runs 10,000–23,000 SHU — above every packet below.

Compared by what actually differs

Bars are scaled against the hottest official Buldak. Where no reliable published figure exists the row says so rather than guessing. Shin Ramyun’s number is the one that circulates in several conflicting versions; the figure here is Nongshim’s own, and the row explains where the rival numbers came from.

Noodle	Maker	Format	Built on	Heat	Buy it if
Shin Ramyun신라면	Nongshim	Soup	Chili	3,400 SHU (2,900 before 2017)	You want the famous one, and the reference everything is measured against
Ansungtangmyun안성탕면	Nongshim	Soup	Soybean paste (된장)	~570 SHU	You want to taste Korean seasoning rather than Korean heat
Buldak, original불닭볶음면	Samyang	Stir-fried	Chili sauce, no broth	~4,404 SHU	You have had a jalapeño and were fine — this is about the same
Buldak 2x Spicy핵불닭볶음면 2x	Samyang	Stir-fried	Chili sauce, no broth	~10,000 SHU	You actively enjoy being uncomfortable
Buldak 3x Haek핵불닭볶음면 3x	Samyang	Stir-fried	Chili sauce, no broth	~13,200 SHU	Almost nobody. This is the hottest official version
Carbo Buldak까르보불닭볶음면	Samyang	Stir-fried	Chili sauce plus cream	Below original — the dairy blunts it	You want the viral one without the dare
Chapaghetti짜파게티	Nongshim	Stir-fried	Black bean (춘장)	Not spicy	You want savoury and sweet rather than hot
Jin Ramen, mild진라면 순한맛	Ottogi	Soup	Beef-savoury, lightly sweet	Effectively not a spicy food — Korean five-year-olds eat it	Someone at the table cannot take heat. This is Korea’s standard answer
Jin Ramen, spicy진라면 매운맛	Ottogi	Soup	Same base as the mild, chili dialled up	Moderate, below Shin Ramyun	You want the bag Koreans actually buy most often — 26.4% on purchase frequency
Neoguri, spicy얼큰한 너구리	Nongshim	Soup, udon-thick noodle	Seafood and kelp	Moderate — the seafood carries it, not the chili	You want depth rather than heat. The kelp square in the packet is real food

Reference points: a fresh cheongyang pepper is 10,000–23,000 SHU, and a jalapeño is 2,500–8,000. Every figure here is sourced from the linked article.

What it costs in Korea

Checked August 2026

Ramyun price is watched more closely in Korea than almost any other grocery item. When Nongshim raised prices in August 2026 it put up cup noodles, snacks and drinks and left bagged ramyun alone — bagged is about 63% of sales, and the ₩1,000 bag works as a public benchmark that is politically expensive to move.

Format	Korean	Price	Where and why	Verified in
Bagged, single	봉지	about ₩1,000	Convenience store. A public price benchmark in Korea	Read →
Bagged, five-pack	봉지 5개입	markedly less per serving	E-Mart, Homeplus or Lotte Mart	Read →
Cup, small	컵라면	₩1,200–1,800	Rose in the August 2026 increase	Read →
Buldak cup	불닭볶음면 컵	about ₩1,800	Stir-fried, so drain rather than fill	Read →

The one rule that saves money: buy single packets at a convenience store only to sample. For anything more, a five-pack at E-Mart, Homeplus or Lotte Mart costs meaningfully less per serving.

How hot is it, really

The head-to-heads

Where the useful decision is between two specific packets.

Ansungtangmyun vs Shin Ramyun

Not mild versus hot. One is a soybean-paste soup and the other is a chili soup — different dishes.

Carbo Buldak

How the creamy version became the export that carried the whole brand.

A bowl of mul-naengmyeon in chilled broth.

Pyongyang vs Hamheung naengmyeon

The cold-noodle decision, which is about broth versus sauce rather than temperature.

Jin Ramen mild vs spicy

One recipe with the chili dialled up, not two. The bag Koreans buy most often, and the third heat grade Korea keeps to itself.

How Koreans actually cook Neoguri

The green square in the packet is Wando kelp, not seasoning — and it is why the broth tastes the way it does.

Buying it outside Korea

Bagged ramyun is one of the few Korean foods that genuinely survives export — it is dry, shelf-stable and made for shipping. The honest caveat is that it costs several times the Korean price abroad, so if you are travelling, buy the five-packs at a mart before you fly rather than paying import pricing later.
