RECIPE: Naturally Fermented Raw Soda

This is a very simple raw soda. You can replace my local herbs with all kinds of aromatic and tasty herbs of your choice, foraged or not, such as mint, anise hyssop, sages, or elderflowers.

I’ve made similar ferments with herbs such as mugwort, California sagebrush, various wild mints, yarrow, elderflowers, pinyon pine branches, white fir (Abies concolor), spruce tips, and others.

Ingredients for a 32-ounce swing-top bottle (1 L)

• 1 sprig black sage
• 1 sprig yerba santa
• ¾ ounce (21 g) fresh gingerroot
• 1 lemon
• 3¼ cups (769 ml) water
• ⅓ cup (79 ml) maple syrup
• ¼ cup (59 ml) Culture Starter

Procedure

1. There’s not much to do here. Place the fresh herbs in your bottle or jar; I like to bruise them gently with my fingers, just enough to facilitate flavor extraction. My next steps are to dice the ginger such that the pieces can go through the opening and then juice my lemon.
2. Pour the water into the bottle, add the ginger pieces, lemon juice, maple syrup, and culture starter. You want the contents to reach up to the bottom of the bottle’s neck but no higher. Close the top.
3. Ferment for 2 to 4 days at room temperature and check the carbonation by opening the top slightly. Usually I get enough carbonation on day 3 or 4.

If I decide to drink the soda at this point, there is no need to strain the contents, but if I’d like to keep it in the fridge for a few more days, I first strain the liquid into a new bottle and leave it at room temperature for another day. This is usually enough to get some decent carbonation going again. Then I place the bottle in the fridge. Every couple of days, I still check the bottle and burp it if necessary.
