How to Make Fermented Pomegranate
Fermented pomegranate arils become jewel-like probiotic treats, their natural tartness enhanced by lactic acid fermentation. The seeds add pleasant crunch.
Category: Fruits · Method: Lactic Acid · Time: 7-14d · Difficulty: 2/5 · Yield: varies · Temp: 18-22°C
History
Pomegranates have been cultivated for millennia in the Middle East. Fermenting the arils is a modern technique that builds on traditions of pomegranate molasses and wine.
Ingredients
- 500g (approx. 3 cups) Pomegranate arils — Freshly extracted, free of white pith
- 2% of total weight Sea salt — Non-iodized; calculate weight of arils + water and multiply by 0.02
- As needed Filtered water — Only use if arils aren't fully submerged; must be mixed with 2% salt
Equipment
- Glass jar
- Fermentation weight
- Bowl
- Cloth cover
Instructions
Extract and Weigh
Remove arils from pomegranates, avoiding any bitter white pith. Weigh the arils on a digital scale to determine the exact salt requirement.
Time: 20 min
Tip: Submerge the pomegranate in a bowl of water while peeling to prevent juice splatter and easily separate floating pith from sinking arils.
Salt and Macerate
Calculate 2% of the arils' weight in salt (e.g., 10g salt for 500g arils). Toss arils with salt in a non-reactive bowl and let sit for 30-60 minutes to draw out juice.
Time: 30-60 min
Tip: Using weight instead of volume ensures a safe environment for Lactobacillus to thrive while inhibiting spoilage bacteria.
Pack and Submerge
Pack the arils and their juices into a clean jar. If the liquid doesn't cover the arils, top with a 2% salt brine (20g salt per 1 liter of water). Use a fermentation weight to keep arils submerged.
Time: 10 min
Tip: Leave at least 1-2 inches of headspace; pomegranates are active fermenters and may bubble vigorously.
Ferment with Airlock
Seal with an airlock to prevent oxygen exposure. Ferment at 18-22°C for 5-10 days. Taste daily after day 5. The ferment is ready when the sweetness has faded and a bright, lactic tang is present.
Time: 5-10 days
Tip: Using an airlock is critical for fruit ferments to prevent Kahm yeast and minimize the risk of alcoholic fermentation.
Fermentation Timeline
- Day 1-2: Rest — Juices release, color deepens.
- Day 3-7: Active — Bubbles form, tang develops.
- Day 7-10: Ready — Tart, probiotic jewels.
Signs of Success & Spoilage
Good signs
- Deep red color
- Tart flavor
- Firm arils
- Light effervescence
Warning signs
- Mushy
- Mold
- Off smell
- Brown color
Troubleshooting
- Floating arils
- Cause: Natural buoyancy and CO2 trapped in seeds Solution: Use a glass fermentation weight and ensure the brine level is at least 1cm above the weight.
- Alcoholic smell
- Cause: Yeast dominance due to high sugar content or high temperature Solution: Ensure a strict 2% salt ratio and keep temperatures below 22°C. If it smells like wine/acetone, discard.
- pH remains high
- Cause: Insufficient fermentation time or low microbial activity Solution: Test with pH strips; the ferment is shelf-stable and safe when the pH is 4.6 or lower (ideally 3.5-4.0).
Storage
Refrigerate in juice Keeps 3-4 weeks. Gorgeous color persists.
