Gochugaru Guide: Choosing Korean Red Pepper Flakes for Kimchi
Gochugaru (고춧가루) is dried Korean red pepper flakes - the essential ingredient that gives kimchi its signature color and flavor. Unlike other chili flakes, gochugaru has a unique combination of heat, sweetness, and slight smokiness.
Key characteristics:
- Bright red color
- Moderately spicy (milder than cayenne)
- Slightly sweet and fruity
- Coarse, flaky texture
- No seeds included
Without gochugaru, you simply can't make traditional kimchi. It's as essential as the cabbage itself.
The Coarse Rule
For kimchi, always choose coarse (굵은) gochugaru. Fine powder makes paste gummy and the visual texture is wrong. Save fine powder for sauces.
Types of Gochugaru
By Coarseness:
Coarse (굵은 고춧가루)
- Chunky, large flakes
- Best for kimchi and most Korean dishes
- Gives traditional texture and appearance
- Most commonly used
Fine/Powder (고운 고춧가루)
- Very finely ground
- Better for smooth sauces and marinades
- Used in gochujang paste
- Disperses heat more evenly
By Quality:
Sun-Dried (태양초)
- Traditional method
- More expensive
- Deeper flavor and color
- Premium choice
Machine-Dried
- More common and affordable
- Perfectly good for kimchi
- Slightly less complex flavor
Check Ingredients
Some "gochugaru" products contain salt, MSG, or other peppers. Read the label - it should just say "dried red pepper" or "Korean red pepper flakes."
How to Choose Gochugaru
Look For:
- Bright, vibrant red color (not brown or dull)
- Made in Korea (check the label)
- Coarse cut for kimchi
- Recent production date
- No added ingredients (pure pepper only)
Brands to Trust:
- Taekyung
- Wang
- Chung Jung One
- CJ
- Any brand from a Korean grocery store
Where to Buy:
- Korean grocery stores (best selection)
- Asian supermarkets
- Online (Amazon, H Mart, etc.)
- Some regular grocery stores in international aisle
Price Guidance: Expect $8-15 for a 1-pound bag. Cheap gochugaru might be old or mixed with other peppers.
Storing Gochugaru
Proper Storage:
- Airtight container (keep original bag sealed or transfer)
- Cool, dark place or refrigerator
- Avoid humidity and heat
Shelf Life:
- Pantry: 6 months at peak quality
- Refrigerator: 1 year
- Freezer: 2+ years
Signs It's Gone Bad:
- Color has faded to brown/orange
- Smells stale or musty
- Lost its fruity aroma
- Clumping from moisture
Tip: Buy in smaller quantities if you don't make kimchi often. Fresh gochugaru makes noticeably better kimchi.

Frequently Asked Questions
Is gochugaru very spicy? Moderately. It's milder than cayenne or Thai chilies. Most people who don't like spicy food can handle small amounts of kimchi. Start with less and increase to taste.
Does gochugaru need to be refrigerated? Not required, but recommended for long storage. It stays fresher longer in the refrigerator or freezer. At room temperature, use within 6 months.
Why is my gochugaru brown instead of red? It's old or was improperly stored. Old gochugaru loses its vibrant color and fruity flavor. It's still safe but won't make great kimchi. Replace it.
How much gochugaru do I need for one batch of kimchi? Typically 3-5 tablespoons per pound of cabbage. A 1-pound bag makes about 5-7 batches of kimchi. Buy a pound to start.
