Rejuvelac: A Journey to Gut Health with Fermented Grains

My earliest encounters with fermentation weren’t in some fancy culinary school, but in my grandmother’s sun-drenched kitchen. She wasn’t making kombucha or kimchi; instead, she was crafting this intriguing cloudy liquid from sprouted grains, something she called “rejuvelac.” The slightly tangy, almost effervescent drink always seemed a bit mysterious, a homemade elixir whispered to be good for what ailed you. It wasn’t until years later, as a professional chef delving into the world of probiotics, that I truly understood the power of that simple, yet potent, beverage. Now, I’m excited to share my version of this classic probiotic drink with you.

Recipe Overview

• Prep Time: 15 minutes + soaking/sprouting time
• Fermentation Time: 2 days
• Total Time: 2 days, 15 minutes
• Yield: 4 cups
• Serves: 4
• Dietary Type: Vegan, Gluten-Free (if using rice or gluten-free oats)

Ingredients

• 1 cup rye berries (or wheat berries, or brown rice, or whole oat groats, or other sproutable grain)
• 8 cups water, divided

Equipment Needed

• Large bowl
• Fine-mesh sieve or colander
• Wide-mouth jar or bowl
• Towel or cheesecloth

Instructions

1. Begin by soaking the grains. In a large bowl, combine the rye berries (or your chosen grain) with 2 cups of water. Ensure all the grains are submerged. Let them soak for 8-12 hours. This initial soak softens the grains and begins the sprouting process.

2. After the soaking period, drain and rinse the grains thoroughly under cold running water. Rinsing removes any starches released during soaking and prevents unwanted bacteria from growing.

3. Repeat the soaking procedure. Place the drained and rinsed grains back into the bowl and add another 2 cups of fresh water. Let them soak again for another 8-12 hours. This process helps to further activate the sprouting. Continue this soak-rinse-soak cycle until you see the grains begin to sprout. You’re looking for small tails to emerge from the grains, indicating that they’re ready for the next stage.

4. Once the grains have sprouted, drain them thoroughly one last time. Excess water can hinder the fermentation process.

5. Transfer the sprouted grains to a wide-mouth jar or bowl. Add 4 cups of water to the jar, ensuring the grains are submerged.

6. Cover the jar loosely with a clean towel or cheesecloth secured with a rubber band. This allows air circulation while preventing fruit flies and other contaminants from entering. Let the jar sit at room temperature (ideally around 70-75°F or 21-24°C) for 2 days, until a white, cloudy liquid forms. This is the rejuvelac.

7. After 2 days, strain the grains using a fine-mesh sieve or colander, reserving the white liquid. The liquid is your rejuvelac.

8. Taste the rejuvelac. It’s ready when it has a tart, slightly lemony taste. This indicates that the fermentation process has created beneficial acids and probiotics.

9. Chill the rejuvelac before drinking directly. It’s also a fantastic addition to smoothies, vegan cheese recipes, or salad dressings.

10. The sprouted grains can be discarded, or preferably composted. They have given up their essence to create this probiotic-rich beverage.

Expert Tips & Tricks

• Water Quality: Use filtered or spring water to avoid chlorine or other chemicals that can inhibit fermentation.
• Temperature Matters: Maintaining a consistent room temperature is crucial for successful fermentation. Avoid placing the jar in direct sunlight or near heat sources.
• Observe and Adjust: The fermentation time may vary depending on the ambient temperature and the type of grain used. Taste the rejuvelac daily after the first day to gauge its progress.
• Sprouting Made Easy: To ensure even sprouting, spread the grains in a thin layer in a wide bowl. This prevents clumping and allows for better air circulation.
• Don’t Over-Ferment: Over-fermented rejuvelac will have an unpleasant, overly sour taste. If this happens, it’s best to discard it and start a fresh batch.
• Second Batch: You can actually get a second, weaker batch of rejuvelac by adding another 4 cups of water to the already used, strained grains, and repeating the fermentation process. The result will be less potent and flavorful, but still usable.

Serving & Storage Suggestions

Rejuvelac is best served chilled. You can drink it straight as a probiotic tonic, or incorporate it into other recipes. Try adding it to smoothies for a tangy boost, or use it as a starter culture for homemade vegan cheeses.

Store rejuvelac in a sealed glass jar in the refrigerator. It will keep for up to 1 week. The taste may become more tart over time as the fermentation continues slowly in the fridge.

It is not recommended to store rejuvelac at room temperature for extended periods, as it will continue to ferment and may become overly sour or develop undesirable bacteria. Freezing is also not recommended, as it can alter the texture and potentially damage the beneficial bacteria.

Variations & Substitutions

• Gluten-Free Rejuvelac: Use brown rice or gluten-free oat groats to make rejuvelac that is suitable for those with gluten sensitivities.
• Herb-Infused Rejuvelac: Add a few sprigs of fresh herbs, such as mint, basil, or rosemary, to the jar during the fermentation process for a subtle flavor infusion.
• Fruit-Infused Rejuvelac: Add a few slices of fruit, such as lemon, ginger, or cucumber, to the jar during the fermentation process for added flavor and nutrients. Be mindful to watch for mold if adding fruit.
• Spiced Rejuvelac: Add a pinch of spices, such as ginger, cinnamon, or turmeric, to the jar during the fermentation process for a warming and flavorful twist.
