Coffee Syrup

  • Bring water to a boil.
  • Turn off heat, add coffee, and let brew for 10-20 minutes.
  • Pour your coffee into a strainer lined with a paper filter into a large bowl.
  • When it’s strained, add liquid coffee that was strained back to your saucepan.
  • Bring to a simmer and add sugar.
  • Let boil for 5 minutes, stirring to dissolve sugar.
  • Remove from heat and let cool

Coffee Water Kefir

  • Add 2-4 tablespoons of the coffee syrup to a 16-ounce bottle.(Make sure you use bottles such as Grolsch or Bormioli thick glass bottles. Bottles bought at craft stores can explode.)
  • Add 14-15 ounces of Basic Water Kefir to the bottle leaving a small amount of room (about 1 inch) at the top. Seal your bottle.
  • 2nd Fermented Water Kefir only needs to sit 1-3 days or until it becomes bubbly. Check it often by opening it to see if it is bubbly. (Warmer homes take less time)
  • Once ready, you can drink or refrigerate for storing. (Drink within 1 week for optimal flavor and benefits.)
  • Note: You can use remaining coffee syrup to make more water kefir or store in the fridge in a jar for up to 3 weeks
