Grapefruit Soda Recipe


  • 1 cup water
  • 9 tbsp sugar
  • Pinch of salt
  • Black pepper
  • 4 cups of fresh squeezed grapefruit juice
  • teaspoon dry champagne yeast


  1. Make a simple syrup by simmering sugar and water over medium low heat until sugar is dissolved.
  2. Let the syrup cool and combine it with the grapefruit juice.
  3. Using a funnel, pour the syrup into a clean 2 liter plastic bottle.
  4. Fill the bottle with water, leaving at least 1 inch of headspace at the top.
  5. Add the yeast to the bottle. Cap it, and shake it up to mix up the yeast.
  6. Let the bottle sit at room temperature for 12 to 48 hours. Check the bottle periodically. When it feels solid and has very little give it is ready.
  7. Refrigerate overnight. It will keep for up to 2 weeks.
  8. Unscrew the cap slightly every day to relieve pressure. Open it slowly to avoid a fountain.
