Homemade Tabasco: A Straight Line Through Fermentation with Taiwanese Chili

Not a Tabasco Clone, But Following Its Logic

I’ve always had a certain respect for Tabasco.

Not because it’s hot, but because it’s extremely simple:

Chili, salt, time, vinegar.

No layers of spices, no sweetness to smooth things out, not even trying to please anyone.

It just does one thing:

Let the chili go through a complete fermentation.

This batch I made isn’t trying to copy Tabasco’s flavor. It’s using its structure, with Taiwanese chili, walking my own path.

The Ingredient: Taiwanese Bird’s Eye Chili

I chose local Taiwanese bird’s eye chili.

The reasons are pretty simple:

• Thick flesh, short fibers
• Concentrated heat with a clear profile
• Not too grassy, clean fruit notes when ripe

This type of chili works great for “process after fermentation” rather than cooking directly into a sauce.

What I want is a linear structure where sour and spicy intertwine—not a spice-heavy hot sauce.

Prep: Coarse Grind with Salt, Not a Puree

The chili gets a coarse grind only.

Right after grinding, mix in the salt immediately.

• Salt amount: 2.5% of chili weight
• When to add: after grinding, before vacuum sealing

This salt isn’t for “seasoning”—it’s for:

• Suppressing unwanted bacteria
• Helping lactic acid bacteria take over
• Drawing out moisture from the chili to create a stable fermentation environment

I don’t want to puree the chili from the start. Coarse particles make fermentation start slower, but also cleaner.

Fermentation: Vacuum Bag × 25°C Water Bath

After mixing with salt, the chili goes into a vacuum bag, sealed, then into the water bath.

• Temperature: 25°C
• Environment: low oxygen
• Salt level: 2.5% (only exists at this stage)
• Time: until acidity stabilizes (about four weeks)

The goal here isn’t wild fermentation. It’s letting lactic acid bacteria work in a comfortable, predictable range.

I’m not chasing complexity. I’m chasing consistency.

Vinegar Comes After Fermentation

The vinegar amount is roughly twice the weight of the chili paste.

After fermentation is done, the chili already has a clear lactic acid profile.

Only then do I add homemade white wine vinegar—not at the start where it would kill the environment.

The order here matters:

1. Complete lactic fermentation first
2. Then use vinegar to extend the acid’s tail
3. Then blend smooth

The difference this makes: the acid isn’t there to “cover up flavors.” It becomes part of the whole flavor structure.

Straining: Keep the Salt in the Structure, Not the Texture

After blending, strain it.

What gets strained out:

• Seeds
• Coarse fibers
• Unnecessary grittiness

What stays:

• The extracted heat
• The acid from fermentation
• The salt feeling dissolved into the liquid structure

At this point, the saltiness won’t taste “salty.” It’s more like a foundation holding up the sour and spicy.

Bottling

Finally, into bottles.

No extra salt added, no adjusting the heat level.

This sauce exists for a simple reason:

Salt handles fermentation. Vinegar handles extension. The chili does the talking.

Final Thoughts

I really like this hot sauce.

The gentle acidity isn’t that sharp vinegar taste—it carries a subtle apple-like aroma.

If you like fermentation, time, and the taste of the chili itself, you’ll probably like this too.
