Water Kefir (Tibicos)

Sugar water fermented by translucent, crystal-like grains into something light, tart and genuinely fizzy — closer to a soda than to a dairy drink, and dairy-free BY NATURE rather than by substitution, which makes it a much better answer than plant-milk kefir for anyone avoiding dairy. The step everyone skips is the minerals.

Ingredients

• 3–4 Tbsp water kefir grains
• 1 quart water

¼ cup sugar (unrefined is better)

• 1 dried fig or other unsulphured dried fruit, OR a pinch of molasses, OR a clean eggshell
• Fruit juice for the second ferment (optional)

Directions

Key ingredients

Water kefir grains, sugar, water — and a mineral source.

1. Dissolve the sugar in the water completely. Room temperature.
2. Add the grains — a few tablespoons per quart.
3. ADD THE MINERALS. This is the part that gets skipped and it is why cultures dwindle and die. Water kefir grains need minerals and trace elements: a slice of dried fig, a piece of unsulphured dried fruit, a pinch of unrefined sugar or molasses, or an eggshell. On pure white sugar and distilled water they starve.
4. Cover loosely, 24–48 hours at room temperature.
5. Strain and re-feed the grains immediately.
6. Second-ferment for fizz: bottle the liquid with a little fruit juice in pressure-capable bottles for 1–2 days, then refrigerate.

Notes

PROVENANCE. Mine.

THESE ARE NOT MILK KEFIR GRAINS and you cannot convert one to the other. Water kefir grains are translucent and gelatinous; milk kefir grains are opaque, lobed and cauliflower-like. Moving milk grains into sugar water will kill them.

DO NOT USE HONEY as the primary sugar — it is antimicrobial and weakens the culture.

USE UNREFINED SUGAR, or add molasses. Refined white sugar alone provides calories and nothing else; the culture needs the trace minerals that refining removes. This is the single most common reason a water kefir culture fades over a few months.

PRESSURE WARNING: a sealed glass bottle of second-fermenting water kefir is a pressure vessel. Use swing-top or heavy bottles, do not over-sugar, refrigerate to stop it, and keep one plastic bottle in the batch as a squeeze-test gauge.

It is a genuinely good way to get a household off commercial soft drinks.
