Serves: 1 quart
Ingredients
- 2 medium sweet potatoes, peeled and chopped
- 1/4 cup sugar
- 1/4 cup whey or probiotic starter
- 1 quart water
Instructions
- Thoroughly wash and peel two medium sweet potatoes, then chop them into small, roughly 1-inch cubes to maximize surface area for fermentation.
- In a clean, sterilized glass jar, place the chopped sweet potato cubes, ensuring they fill approximately 1/3 of the jar's volume.
- Add 1/4 cup of sugar directly over the sweet potato cubes, which will help feed the fermentation process and create a slightly sweeter kvass.
- Pour 1/4 cup of whey or probiotic starter culture over the sweet potatoes and sugar, which will introduce beneficial bacteria to initiate fermentation.
- Slowly add 1 quart of filtered or spring water to the jar, leaving about 1-2 inches of headspace at the top to allow for fermentation expansion.
- Cover the jar with a breathable cloth or coffee filter secured with a rubber band to allow air circulation while preventing contamination.
- Place the jar in a warm, dark location with a consistent temperature between 70-75°F (21-24°C) for optimal fermentation.
- Let the mixture ferment for 2-3 days, gently stirring or swirling the jar once daily to distribute the cultures and prevent mold growth.
- After 2-3 days, strain the liquid through a fine-mesh strainer or cheesecloth, separating the kvass from the sweet potato solids.
- Transfer the strained kvass into clean bottles and refrigerate. The kvass will continue to develop flavor and can be consumed immediately or stored for up to one week.
- Optional: For a second fermentation, reserve a small amount of the liquid as a starter for your next batch, which can enhance probiotic content and flavor complexity.
Tips
- Always use clean, sterilized equipment to prevent unwanted bacterial growth and ensure a successful fermentation.
- Choose organic sweet potatoes if possible, as they tend to have more robust natural yeasts that can enhance fermentation.
- Water quality matters! Use filtered or spring water to avoid chlorine, which can inhibit fermentation.
- Monitor the fermentation temperature carefully—too cold, and fermentation will be slow; too hot, and you risk off-flavors or spoilage.
- Trust your senses: If the kvass smells unpleasant or shows signs of mold, discard the batch and start over.
- Experiment with adding spices like ginger or cinnamon during the initial fermentation for extra flavor complexity.
- Save a small amount of each batch as a starter for your next fermentation to build a more robust probiotic culture.
