Pinecone soda uses the natural yeast on unripe pinecones and sugar water to create a naturally fermented soda. 

Ingredients

Units Scale
  • Green (unripe) pinecones – about a handful
  • 3/4 cup (150 g) granulated white or brown sugar
  • 2 quarts (about 2 liters) good quality non-chlorinated water

Instructions

Start with a half gallon (~2 liter) glass jar and pour in 3/4 cup (150 g) sugar. Fill the jar with water, and add some unripe pinecones. Place a lid on the jar tight enough to keep dust out, but loose enough for gases to escape.

Each day, tighten the lid and shake the jar 2-3 times per day for about 10 seconds each time. (Loosen the lid again after shaking.) You should see bubbles within 2 to 3 days.

Once you see bubbles, you start working with your soda. Continue shaking each day, and taste test. When you like the flavor, remove the cones, strain, bottle, and refrigerate. Best if consumed within a week or so.

Notes

If you’d like to make a mildly alcoholic drink, you can add extra sugar, and let it ferment longer. The sugars eventually convert to alcohol.

For bottling, use bail top bottles or recycled plastic soda bottles. You want a container that is strong enough to hold up to carbonation build up.
