Fermented beets are one of the easiest vegetables to ferment at home, requiring minimal equipment and ingredients. Whether you’re new to fermentation or looking to expand your gut-health kitchen, this straightforward method produces tangy, probiotic-rich beets that complement any meal. In just a week, you’ll have a shelf-stable condiment packed with naturally occurring beneficial bacteria.
How to Make Lacto-Fermented Beets
This method relies on salt and time to create an environment where lactobacillus bacteria thrive. The process is forgiving and requires only basic kitchen equipment.
Ingredients
- 2-3 pounds fresh beets, firm and medium-sized
- Sea salt or kosher salt (non-iodized), about 2 tablespoons per quart of brine
- Filtered or dechlorinated water, 2-3 cups
- Optional seasonings: dill, garlic cloves, peppercorns, or cinnamon sticks
Method
Prepare Your Beets
Scrub beets under running water to remove soil, then peel them using a vegetable peeler or knife. You can leave small beets whole, but slice larger ones into 1/4-inch rounds or sticks. Pat dry with a clean cloth to remove excess moisture before placing them in your container.
Create the Brine Solution
Dissolve salt in filtered water at a ratio of approximately 2 tablespoons salt per quart of water. Stir until salt is completely dissolved. Taste the brine–it should be pleasantly salty, like a potato chip. This salinity prevents harmful bacteria while allowing beneficial lactobacillus to flourish.
Pack Your Fermentation Vessel
Place beets and any optional seasonings into a clean glass jar. Layer them loosely rather than packing tightly, as the fermentation process creates gases that need room to move. Leave at least 2 inches of headspace at the top of the jar.
Submerge the Beets Completely
Pour brine over the beets until they are fully covered. Any beet pieces exposed to air above the brine line can develop mold. Use a fermentation weight, glass lid insert, or even a small glass placed inside the jar to keep everything submerged below the liquid.
Cover and Set in a Cool Location
Place a breathable cover like cheesecloth or a coffee filter over the jar’s opening, secured with a rubber band. This allows gases to escape while preventing dust and insects from entering. Set the jar on a kitchen counter away from direct sunlight at room temperature (60-75F is ideal).
Monitor and Taste Daily
Check your ferment each day. You may see cloudy sediment, tiny bubbles, or a white film form on the surface–these are all signs of healthy fermentation. Starting on day 3, remove the cover and taste a small piece of beet. They’ll become increasingly tangy as fermentation progresses.
Bottle When Flavor is Right
Once beets reach your preferred tanginess (usually 3-7 days), strain out the beets using a fine mesh strainer, reserving the brine. Pack fermented beets into clean jars, cover with their fermentation liquid, seal with lids, and refrigerate. Cold slows fermentation dramatically, preserving your product.
- If white surface mold (kahm yeast) appears, skim it off gently–it won’t harm your ferment, though it indicates fermentation may slow. Keep everything below the brine line to prevent it.
- Save your fermentation brine after bottling. Use it as a probiotic tonic, a salad dressing base, or to start your next batch of fermented vegetables.
- Fermented beets last 4-6 months refrigerated in sealed jars. Label yours with the fermentation date so you remember when they’re ready to enjoy.
What to Look For in Fermentation Equipment
- Glass Jar Quality and Size: Choose wide-mouth glass jars with straight sides, ideally quart-sized (32 oz) or larger. Straight sides make it easier to pack and remove beets, while glass doesn’t react with salt or acids. Avoid jars with narrow openings that make packing difficult.
- Fermentation Weights or Keepers: A proper weight keeps vegetables submerged, which is essential for success. Look for glass weights, ceramic discs, or stainless steel springs designed for fermentation. Improvised solutions like smaller jars can work but may break under pressure.
- Breathable Covers: Standard metal lids trap gases and can create pressure. Instead, use cloth covers, coffee filters, or specialized airlock lids that let CO2 escape while preventing contamination. This prevents messy overflow and explosive bottles.
- Salt and Water Quality: Use non-iodized sea salt or kosher salt, never table salt with iodine or anti-caking agents. Similarly, filter your water or let tap water sit uncovered 24 hours to allow chlorine to evaporate. Both elements support fermentation success.

Fermented beets are one of the most rewarding fermentation projects for beginners because they’re nearly impossible to fail and deliver results in just a few days. The minimal equipment needed–a jar, salt, water, and beets–means you can start this weekend with items already in your kitchen. The health benefits of consuming live probiotics, along with the satisfaction of creating shelf-stable food from scratch, make this a worthwhile addition to your homestead or kitchen routine.
Begin with a single quart jar and one batch. Pay attention to how your specific kitchen environment affects fermentation timing, taste, and texture. Once you experience success, you’ll likely find yourself fermenting beets regularly, experimenting with flavor combinations, and perhaps expanding to other vegetables. The equipment investments you make now will serve you for decades, creating a foundation for a lifelong fermentation practice.
Frequently Asked Questions
How do I know if my fermented beets are safe to eat?
Safe ferments smell pleasantly tangy and sour, not rotten. The beets should be fully submerged (preventing mold), and the brine should remain clear or slightly cloudy. If you see fuzzy mold, smell ammonia or decay, or notice slime on the beets themselves, discard the batch. White surface film (kahm yeast) is harmless and can simply be skimmed off.
Can I ferment beets at room temperature, or do they need to be cold?
Room temperature (60-75F) is perfect for initial fermentation. Cooler temperatures (50-60F) slow fermentation but produce more complex flavors; warmer temperatures (above 75F) speed fermentation but may create mushier beets. Once fermentation is complete, refrigeration preserves the final product for months by nearly halting bacterial activity.
Why do my fermented beets taste mushy or soft instead of crisp?
High temperatures and prolonged fermentation soften beets. Ferment at cooler room temperatures and taste daily starting on day 3 to bottle them earlier. Using whole smaller beets instead of slices also maintains better texture. A pinch of tannins from grape leaves or horseradish added to the brine can help preserve crunchiness.
Do fermented beets need to stay in the refrigerator permanently?
Once bottled and sealed, refrigeration dramatically slows fermentation and extends shelf life to 4-6 months. If you prefer room-temperature storage, use a dedicated airlock lid design that prevents contamination while allowing controlled fermentation to continue slowly over months.
Can I reuse the brine from my first batch to ferment new beets?
Absolutely. The brine from a successful ferment contains beneficial lactobacillus bacteria that can jump-start a new batch. Filter out any sediment, and use the brine as your liquid base for the next fermentation. This creates increasingly complex flavors over successive batches, similar to sourdough starter development.
