Whey Soda

Step 1

If using juice, simply combine the juice and whey in a half-gallon (2-L) jar. If using sweetened teas or water, steep the tea at a rate of 1 teaspoon (1 g) of herb per cup of water. Strain and add the sugar while still hot. Allow to cool before combining with the whey and other flavorings.

Step 2

Seal the jar with a lid and allow to ferment for 2 to 6 days, depending on the temperature. Transfer the liquid to airtight bottles for a second fermentation of 1 to 3 days. Pour over ice and consume immediately or transfer to the refrigerator for 1 to 2 weeks.

Step 3

For lemonade, use ½ cup fresh lemon juice with the sugar and water.

Step 4

For a honey-sweetened version, replace the sugar with ½ cup raw honey.

Step 5

For root beer, use ⅓ cup of Root Beer Syrup in combination with the sugar, whey and water.
