Hottest instant ramen noodles ranked by Scoville: From Buldak to Ghost Pepper
The hottest commercially produced instant ramen noodles are Culley's World's Hottest Ramen (averaging over 1,000,000 SHU with pure Carolina Reaper mash), followed by Daebak Ghost Pepper Spicy Chicken Noodles (advertised at 1,000,000 SHU for the sauce concentrate, with prepared broth measuring roughly 350,000 to 400,000 SHU), Samyang Buldak 3x Spicy (13,200 SHU), and the viral Samyang Buldak 2x Spicy (10,000 SHU).

The spicy ramen phenomenon: Sauce packet vs prepared broth Scoville
Over the past decade, viral spicy noodle challenges on YouTube and TikTok have turned instant ramen into an extreme Scoville competition [1]. However, consumers frequently confuse sauce packet ratings with the heat of the finished soup [2].
Manufacturers measure Scoville Heat Units on the concentrated pepper oil or chili mash inside the flavoring packet [2]. Once boiling water (typically 400 to 500 mL) is added, dilution physics reduce the effective Scoville concentration of the broth by 60% to 75% unless the noodles are drained dry style [1][2].
Samyang Buldak series: The benchmark Korean fire noodles
Produced by South Korea's Samyang Foods since 2012, the Buldak Bokkeum Myeon line established the global standard for dry stirred spicy ramen [1].
Original Buldak: Rated at 4,404 SHU, roughly equivalent to a mild fresh jalapeño pepper [1].
Buldak 2x Spicy (Haek-Buldak): Rated at 8,808 to 10,000 SHU, putting it on par with a pungent serrano chili [1]. It features deep fermented gochujang sweetness backed by sharp habanero extract [1].
Buldak 3x Spicy: Released as a high-potency limited edition measuring 13,200 SHU, triple the heat of the original red packet [1].
The extreme tier: Daebak Ghost Pepper & Carolina Reaper noodles
For chili heads beyond the Buldak threshold, specialty makers have incorporated genuine superhot chili mashes [2].
Daebak Ghost Pepper Spicy Chicken (Mamee Malaysia): Formulated with genuine Bhut Jolokia extract and black cocoa-tinted noodles [2]. The sauce concentrate hits an astronomical 1,000,000 SHU, producing a delayed throat burn that persists for over 20 minutes [2].
Culley's World's Hottest Ramen (New Zealand): Created in collaboration with chili breeder Ed Currie, this broth incorporates Carolina Reaper puree and exceeds 1,000,000 SHU in the prepared bowl [2].
How to survive the spicy ramen challenge: Science-backed relief
Because instant ramen is served piping hot, heat receptors experience a double assault [3]. Thermal heat activates oral TRPV1 receptors at 43°C (109°F), compounding capsaicin's neurochemical burn [3].
Allow the noodles to cool slightly before eating [3]. Never drink carbonated soda or cold beer, which mechanically agitate the mucosa; keep whole milk, sweetened condensed milk, or dairy ice cream on hand to dissolve hydrophobic capsaicinoids [1][3].

What doesn’t work
- Eating extreme challenge ramen on an empty stomach: capsaicin stimulates intense gastric acid secretion, causing severe stomach cramps and nausea [3].
- Drinking water or carbonated soda during the burn: bubbles agitate sensitive nerve endings and spread capsaicin oils across your esophagus [1].
- Slurping noodles aggressively: rapid inhalation can pull atomized chili oil droplets directly into the trachea, triggering uncontrollable coughing fits [2].
- Leaving contact lenses in while preparing superhot ramen: chili oil on fingers easily transfers to lenses during removal [2].
Questions
How hot is Buldak 2x Spicy ramen in Scoville units?
Samyang Buldak 2x Spicy is officially rated between 8,808 and 10,000 SHU, roughly twice as hot as original Buldak and comparable to a hot serrano pepper.
Is Daebak Ghost Pepper ramen really 1,000,000 Scoville?
The chili extract seasoning packet is benchmarked at 1,000,000 SHU using Bhut Jolokia. In the finished, prepared cup, the effective broth heat is estimated around 350,000 to 400,000 SHU due to dilution.
Why does spicy ramen cause stomach aches hours later?
Capsaicin binds to TRPV1 receptors in the stomach and intestines, accelerating peristalsis and triggering gastric spasms known colloquially as 'the fire in the gut'.
What is the hottest instant ramen in the world?
Culley's World's Hottest Ramen (made with Carolina Reaper) and 18-Kin (18+ Curry Ramen from Japan) are the two hottest commercially certified noodles, both exceeding 1,000,000 SHU.
