Additionally, Shin Red,[3] introduced in 2020, is a vibrant and extra-spicy variant that appeals to those seeking an intensified heat experience.

This version maintains the signature taste of the original Shin Ramyun while offering an even hotter flavor profile.

Like the other varieties, a standard package of Shin Red includes noodles, a seasoning powder, and vegetable flakes.

The Nongshim R&D team was inspired by sogogi jangguk, a popular Korean spicy cabbage and beef stew.

[4] After Shin Ramyun was introduced, Nongshim's share of the instant noodle market hit 46.3% in 1987, and exceeded 50% for the first time in 1988 (53.8%).

In August 2014, Nongshim revised its recipe for noodle blocks across its line for a chewier consistency, along with a revamped external packaging.

Shin Ramyun uses red and black packaging with the emphasized calligraphic form of the Hanja character "辛", which means "spicy".

[12] Most of its commercials include a famous male celebrity, frequently with his family, who is eating Shin Ramyun at home.

Adding a simple yet catchy jingle at the end of their commercials is one of Nongshim's important marketing strategies.

[16] In China, Nongshim uses a slogan: 사나이라면 매운맛을 먹을 줄 알아야지 (Traditional Chinese: 吃不了辣味非好漢; Translation: (He who cannot handle spice is not a true man).

[17] This slogan is from a famous phrase in China "不到長城非好漢 (He who has never been to the Great Wall is not a true man)" by Mao Zedong.
