What Are Lacto Fermented Pickles?
Lacto fermented pickles are cucumbers preserved in a saltwater brine rather than vinegar. During fermentation, naturally occurring beneficial bacteria consume the sugars in the cucumbers and produce lactic acid. This natural acid preserves the pickles while creating their signature tangy flavor.
Unlike vinegar pickles, which rely on added acid, this lacto-fermented pickles recipe develops its flavor naturally over several days.
Ingredients
You’ll only need a handful of simple ingredients to make these traditional fermented dill pickles.
- 2 pounds small pickling cucumbers (Kirby preferred) or mini/Persian cucumbers
- 4–6 sprigs fresh dill
- 4 garlic cloves, thinly sliced
- 1 teaspoon whole mustard seeds (optional)
- ½ teaspoon whole black peppercorns
- 1 oak leaf (preferred) or 1–2 grape leaves (optional, for extra crisp pickles)
- 2 fresh bay leaves (optional)
Salt Brine
- 5 cups filtered water
- 2 tablespoons fine sea salt
How to This Make Fermented Pickles Recipe No Vinegar
1. Soak The Cucumbers
Wash the cucumbers thoroughly under cool running water to remove any dirt. For the crispiest pickles, soak them in an ice water bath for 1–2 hours before fermenting, then drain well.
2. Trim the blossom end
Trim about ⅛ inch from the blossom end (flowering end) of each cucumber. This helps remove natural enzymes that can cause pickles to soften during fermentation, resulting in a crispier finished pickle.
3. Pack the jars
In a large, clean two-quart mason jar (or two 32 oz mason jars), place all the whole spices into the bottom. Then add the dill and garlic. With clean hands, pack one layer of cucumbers tightly, standing on end, then add the bay leaves, then add the second layer of cucumbers standing on end. Or if using two 32 oz mason jars you’ll only do one layer. Press everything down, leaving 1 ½ inches of headroom.
4. Prepare the brine
In a measuring cup or bowl, whisk together the filtered water and sea salt until the salt has completely dissolved. After experimenting with many different salt ratios, I prefer a 3% salt brine. This salt concentration creates the ideal environment for beneficial lactic acid bacteria to thrive while helping keep unwanted bacteria at bay, resulting in crisp, flavorful fermented pickles.
5. Add the brine
Pour the salt brine over the cucumbers until they’re fully covered, leaving about 1 inch of headspace. . Place a glass fermentation weight on top to keep everything submerged.
5. Ferment
Ferment the Pickles: Cover the jar with an airlock lid or a regular lid left slightly loose to allow gases to escape. Place the jar in a cool spot out of direct sunlight (ideally 68–72°F) and ferment for 5–10 days. The brine will become cloudy and small bubbles may appear—both are normal signs of fermentation.
Begin tasting the pickles around day 5. They’ll have a light tang at first, while the sweet spot is usually 6–8 days, when the flavor is well-developed and the pickles are still wonderfully crisp. By day 9–10, they’ll be tangier and slightly softer.
I prefer a shorter ferment (around 5 days) as it results in a crispier pickle and slightly less tang. Once the pickles reach your preferred flavor, transfer the jar to the refrigerator to slow fermentation and preserve their crisp texture.
6. Refrigerate
Once the pickles reach your preferred level of tanginess, cover with an airtight lid and transfer them to the refrigerator or another cool place for cold storage. The flavor will continue to develop slowly while staying wonderfully crisp.
During fermentation the pickles will gradually change from bright green to a more muted olive green. This color change is completely normal and is a sign that fermentation is progressing.
Why I Use a 3% Salt Brine
A 3% salt brine is my preferred ratio because it creates the ideal environment for beneficial lactic acid bacteria to thrive while slowing the growth of unwanted bacteria. As the cucumbers ferment, these beneficial bacteria produce the tangy flavor and natural probiotics that make fermented pickles so delicious.
I’ve found that 3% is the sweet spot. It’s salty enough to help keep pickles crisp and support a healthy fermentation, but not so salty that it slows the process or overpowers the flavor. Combined with fresh cucumbers, a tannin-rich oak or grape leaf, and keeping the cucumbers fully submerged, it consistently produces crisp, flavorful fermented pickles.
Expert Tips
A few simple techniques make all the difference when making the best fermented pickles recipe.
Start with the Freshest Cucumbers
Freshly picked cucumbers produce the crispiest pickles. Kirby cucumbers are ideal, but mini cucumbers are an excellent substitute if you can’t find traditional pickling cucumbers.
Soak the Cucumbers in Ice Water
An ice bath for about 30 minutes to two hours helps rehydrate the cucumbers before fermentation and improves their final crunch.
Trim the Blossom End
Cut a thin slice from the blossom end of each cucumber. This removes natural enzymes that can soften the pickles during fermentation.
Don’t Cut Your Cucumbers
Leaving your cucumbers whole during fermentation will result in a crispier pickle.
Keep Everything Below the Brine
The top of the cucumbers should always stay beneath the saltwater brine. I recommend using a glass fermentation weight to prevent the cucumbers or any ingredients from floating above the liquid, where unwanted bacteria and mold are more likely to develop.
Use Filtered Water
Always use filtered water rather than chlorinated tap water. Chlorine can slow or inhibit the growth of the beneficial bacteria that make fermentation possible.
Don’t Worry About Cloudy Brine
A cloudy brine is completely normal and is actually a good sign that fermentation is active. As the healthy bacteria multiply, the brine naturally becomes cloudy.
Airlock Lids Make Fermentation Easier
An airlock lid is my favorite option because it automatically releases carbon dioxide while preventing oxygen from entering the jar. If you don’t have one, simply use a loose lid and burp the jars once a day.
Refrigerate at the Right Time
Begin tasting your pickles around day 5. Once they’ve reached your preferred level of tanginess, move them to the refrigerator or other cold storage to dramatically slow fermentation and preserve their crisp texture.
Storage
Store finished fermented pickles in the refrigerator or another cool place.
They’ll stay delicious for 2–3 months, and often much longer when kept consistently cold.
Before refrigeration, people traditionally stored fermented vegetables in root cellars, where the cool temperatures slowed fermentation naturally.
Frequently Asked Questions
How long do you lacto ferment pickles?
Most pickles ferment for 5–7 days at room temperature (68–75°F). Smaller cucumbers may be ready in as little as 4 days, while larger cucumbers can take closer to a week. Begin tasting after day 4 and refrigerate once they reach your preferred flavor.
Are lacto fermented pickles healthy?
Yes! Because they aren’t made with vinegar or heat processed, they contain naturally occurring healthy probiotics and beneficial bacteria that may support gut health. They’re also a delicious probiotic-rich snack made from simple whole-food ingredients.
What are common problems in lacto-fermentation?
The most common issues include soft pickles, mold, or slow fermentation. These are usually caused by cucumbers floating above the brine, using chlorinated water instead of filtered water, fermenting in temperatures that are too warm or too cold, or allowing unwanted bacteria to grow because the vegetables weren’t fully submerged. A cloudy brine is expected and is a sign of active fermentation.
How do you keep pickles crisp when fermenting?
For the crispiest pickles, start with fresh cucumbers, soak them in an ice bath, trim the blossom end, keep them completely submerged beneath the brine with a glass fermentation weight, and add fresh bay leaves if desired. Refrigerate the pickles as soon as they reach your preferred level of sourness to preserve their crunch.
Final Thoughts
If you’ve never made a fermented pickles recipe no vinegar, you’ll be amazed by how simple and rewarding it is. This traditional method creates crisp, tangy dill pickles packed with natural flavor—no vinegar or canning required.
Whether you’re new to fermentation or already love homemade ferments, this fermented pickles recipe is an easy way to enjoy real food made the old-fashioned way. Once you taste these crunchy lacto fermented pickles, you’ll never want to go back to store-bought pickles again.
