History
Original cola recipes used kola nuts, coca leaves, and various spices. This kefir version recreates cola flavor using cinnamon, vanilla, citrus, and other warming spices fermented with probiotic cultures.
Ingredients
- 1 quart Water kefir — Finished first ferment; ensure it still has a hint of sweetness or add 1 tsp sugar for carbonation.
- 1 Cinnamon stick — Ceylon preferred
- 1/2 tsp Vanilla extract — Or 1 inch vanilla bean
- 1 tbsp Orange zest — Fresh
- 2 tbsp Lime juice — Fresh
- Pinch Nutmeg — Freshly grated
- 1 whole Star anise — Optional
- 1-2 tsp Molasses or Caramelized Sugar — Essential for the signature dark cola color and to provide fuel for carbonation.
Equipment
- Glass bottles
- Fine strainer
- Small pot for spice infusion
- Funnel
Instructions
Make spice concentrate
Simmer cinnamon, star anise, nutmeg, and molasses/caramelized sugar in 1/2 cup water for 10 minutes. This creates the 'cola syrup' base. Cool completely.
Time: 15 min
Tip: Don't boil - gentle simmer extracts flavor without bitterness.
Second ferment
Ferment 12-24 hours at room temperature until carbonated. SAFETY WARNING: Pressure builds rapidly in sealed bottles. Use at least one plastic 'tester' bottle; when the plastic feels rock-hard, the glass bottles are ready to be moved to the fridge.
Time: 12-24 hours
Tip: Burp bottles carefully if you suspect over-carbonation to prevent 'bottle bombs' or geysers.
