Korean Gochugaru: Chili Flake Guide

By Liam Foster · September 30, 2026

What Is Gochugaru?

Gochugaru (고추가루) are Korean chili flakes made from sun-dried red peppers. They're a staple in Korean cooking — the base for kimchi, gochujang, and countless banchan (side dishes).

Types

Coarse (굵은 고춧가루): For kimchi — larger flakes with seeds
Fine (고운 고춧가루): For gochujang and sauces — smooth, seedless powder
Hot (매운): Made from spicier pepper varieties
Mild (덜 매운): Made from milder peppers, more fruity sweetness

Heat Level

Korean chili flakes are moderate heat (4,000-10,000 SHU) — less than cayenne (30,000-50,000 SHU) but more than paprika. They're prized more for flavor and color than heat.

Storage

Store in the freezer or fridge — gochugaru oxidizes and turns brown at room temperature. A sealed bag in the freezer keeps it bright red and fresh for up to a year.
