How to Make It
Start your fermentation journey with these simple steps.
Simmer the Berries
In a large pot, combine the raspberries and sugar with 2 quarts of filtered water. Simmer for 20-30 minutes to dissolve the sugar and release berry flavors.
Cool and Strain
Let the mixture cool to room temperature. Strain out the berries to obtain sugary raspberry juice.
Transfer to Fermentation Vessel
Pour the juice into a clean 2-quart glass jar or demijohn.
Add the Starter Culture
Add ½ cup of whey or equivalent starter culture. Stir well to combine.
Fermentation Process
Cover the jar with a cloth or paper towel secured with a rubber band. Place it in a warm, dark place for at least 3 days until slightly fizzy. Taste periodically to check for your desired sweetness.
Bottling
Transfer the soda into clean glass bottles using a funnel, leaving an inch of headspace. Seal the bottles tightly to keep the fizz in.
Secondary Fermentation
Leave the bottles at room temperature for 1-2 days, checking daily and releasing pressure as needed to prevent bursting.
Refrigerate and Enjoy
Transfer the bottles to the refrigerator to slow fermentation. Serve chilled and enjoy your refreshing, bubbly Fermented Berry Soda!
