🔥 How to Ferment Hot Sauce in Oak Barrels
🧂 What You’ll Need:
- Fresh chili peppers (any type you prefer)
- Salt (non-iodized, like sea salt or kosher salt)
- Water (preferably filtered)
- Vinegar (added after fermentation)
- Oak barrel (charred, plain, or spirit-rinsed) Our barrels are perfect for this.
- Funnel
- Blender or food processor
- Optional: Whiskey, bourbon, tequila for rinsing barrel
🛢️ Step 1: Prep Your Barrel
Brand-new or used?
- New oak barrels give a cleaner, woody flavor.
- Used spirit barrels add rich, complex notes from bourbon, whiskey, or tequila.
Tip: If you're not using a previously filled spirits barrel, you can fill your barrel with a few ounces of whiskey, bourbon or tequila, swirl it around, let it sit for 2 to 3 weeks and then pour it out (Or drink it-Yum.) This mimics some of that spirit-aging character.
🌶️ Step 2: Make the Pepper Mash
- Chop your peppers – remove stems, and optionally some seeds if you want less heat.
- Blend into a mash. Add a bit of water to help it process.
- Make a brine – dissolve salt in water. A good ratio:
🧂 2–3% salt by weight of the total mash. (Example: 30g salt per 1L of mash.)
- Combine the brine and mash, and blend until smooth if desired.
🪣 Step 3: Fill the Barrel
- Use a funnel to pour your pepper mash into your oak barrel. Order our Pepper Mash option!
- Leave at least 10% headspace to allow for gas buildup during fermentation.
- Seal the barrel with its bung.
⏳ Step 4: Ferment
- Store in a cool, dark place (60–75°F / 15–24°C).
- Typical fermentation time: 4 weeks minimum — up to several months or even a year for deeper flavor.
- Check occasionally for mold or pressure buildup.
- If your barrel allows gas to escape, you're good.
- If not, open the bung weekly to burp any pressure.
🧪 Step 5: Add Vinegar
Once fermentation is complete to your taste:
- Add vinegar (typically 10–30% of the batch) to stop fermentation and balance acidity.
- Apple cider vinegar and white vinegar are common choices.
🧴 Step 6: Final Touches
- Strain if you want a smoother sauce.
- Bottle and refrigerate. It will last for months, even longer with proper acidity (pH below 4.6).
🔄 Optional Flavor Variations:
- Rinse your barrel with tequila for a smoky, agave-rich profile.
- Use fruit additions like mango or pineapple in the mash for a sweet heat.
- Add roasted garlic or onions for savory depth.
- Barrels Farm can customize you barrel with a larger bug opening to make it easier to add your pepper mash.
