Ingredients You’ll Need
What’s magical about Brine-Pickled (Fermented) Peperoncini is how a handful of honest ingredients can work together to create such complex flavor. Every component does its part, from infusing the peppers with gentle spice to building the briny bath where probiotic magic happens.
- Peperoncini Peppers (1 pound): Look for vibrant, firm, and blemish-free pods—these are the stars of the show and will retain their texture and gentle heat.
- Filtered Water (4 cups): Always use filtered or non-chlorinated water to help friendly bacteria thrive during fermentation.
- Kosher or Sea Salt (3 tablespoons, non-iodized): Salt not only seasons but also creates an environment that encourages good bacteria and repels the bad.
- Garlic (2 cloves, smashed): Adds delightful aroma and a mild bite that permeates the whole batch.
- Black Peppercorns (1 teaspoon): Sprinkle in subtle heat and a rich, earthy backbone to the brine.
- Mustard Seeds (1 teaspoon, optional): For those who enjoy a whisper of tangy complexity—mustard seeds make the flavor pop.
- Bay Leaves (2): These add an herbal, almost tea-like note that balances the punchy flavors.
How to Make Brine-Pickled (Fermented) Peperoncini
Step 1: Prepare the Peppers
Begin by giving your peperoncini a gentle but thorough wash. Make sure to scrub away any garden grit or waxy residue, as clean peppers equal a clean ferment. Trim the stems if they’re long or woody, but leave the peppers whole so they maintain their satisfying snap and beautiful appearance in the jar.
Step 2: Pack the Jar
Take a sparkling-clean glass jar or fermentation crock and start packing in the peppers. Layer in the smashed garlic cloves, black peppercorns, bay leaves, and (if you’re tempted) the mustard seeds for that extra punch. Nestle everything tightly—the more snug, the less chance the peppers will float and expose themselves to air.
Step 3: Mix the Brine
In a bowl or large measuring jug, stir kosher or sea salt into room-temperature filtered water until it dissolves completely. This saltwater is the heart of the fermentation, encouraging probiotics to thrive while keeping unwelcome guests at bay.
Step 4: Submerge and Weigh Down
Slowly pour the brine over your peppers until they are completely submerged. If needed, use a fermentation weight, a cleaned smaller jar, or even a ziplock bag filled with brine to gently keep everything under the liquid. This step is crucial—peppers exposed to air will spoil.
Step 5: Cover and Ferment
Cover the jar with a lid loosely (so gases can escape) or secure a clean cloth with a rubber band. Place the jar at room temperature, out of direct sunlight. Check daily—make sure all the peppers stay submerged and notice how the brine turns a little cloudy and bubbly. Start tasting after 7 days; let them go up to 14 for deeper tanginess, then refrigerate to slow further fermentation.

Make Ahead and Storage
Storing Leftovers
Once fermented to your liking, keep your Brine-Pickled (Fermented) Peperoncini sealed in the refrigerator. They’ll happily last for up to six months, staying tangy, crisp, and ready to lend pep to meals at a moment’s notice. Make sure peppers are always submerged in brine for best quality.
Freezing
Fermented peppers aren’t usually frozen, as it can damage their unique crunch and muddle the flavors. For long-term storage, simply keep them refrigerated, or share extra jars with friends—these peppers are best enjoyed fresh from the fridge.

FAQs
Can I use regular tap water?
It’s highly recommended to use filtered or non-chlorinated water, because chlorine in tap water can inhibit the beneficial bacteria that make fermentation possible. If filtered water isn’t accessible, let tap water sit out uncovered overnight to help some chlorine dissipate.
Do I have to trim the stems off the peppers?
No, but you can trim if they’re long or tough. Keeping the peppers mostly whole helps them stay crisp and look beautiful in your jar, though a tiny slit can help peppers ferment more evenly if you like extra tang.
What if I see white film or bubbles forming on the brine?
That’s perfectly normal! A white film (known as kahm yeast) and bubbles signal healthy fermentation. Simply skim off any white spots from the surface with a clean spoon, but discard the batch only if you see fuzzy, colorful mold or detect an off smell.
My peppers are soft—not crunchy. What went wrong?
Usually, peppers soften if the ferment gets too warm or if the peppers weren’t very fresh to begin with. Next time, make sure your fridge is set cold enough and use the freshest peppers possible for max crunch.
Can I reuse the brine for another batch?
It’s best to make a fresh brine each time for consistent results and safety, but you can use a tablespoon of leftover brine to help kickstart a new ferment if you’d like. Just remember to mind cleanliness and avoid any off-smelling or discolored brine.
