What you need
- 50 g hydrated water kefir grains (about 3 tablespoons)
- 50 g plain or unrefined cane sugar
- 900 g filtered or dechlorinated water
- Optional: 1 dried fig or a few raisins for the jar
- For the bottles, per liter: 10 g of fresh ginger, thinly sliced, and the zest and juice of half a lemon
Required gear
- Wide-mouth glass jar, 1.5 liters
- Clean cloth or coffee filter, and a rubber band
- Plastic or nylon strainer (not metal)
- Scale accurate to 1 g
- Pressure-rated glass bottles with tight caps, for the second stage
- Funnel
Step-by-step protocol
- 0:00Dissolve the sugar in 250 g of warm water, then add 650 g of cool, filtered or dechlorinated water. The sugar water must be at room temperature, below 30°C, before the grains go in.
- +10 minPour it into a clean glass jar, add the grains (and the dried fig, if using), and cover the jar loosely with a clean cloth or coffee filter and a rubber band.
- Day 1-2Leave it out of direct sun at 20 to 25°C for 24 to 48 hours. It is ready when it tastes lightly sweet and tart rather than sugary and a few bubbles rise when you tap the jar.
- Day 2Strain the liquid into a bowl through a plastic or nylon strainer. Start the next batch with the grains, or store them in sugar water in the refrigerator.
- +5 minPut the ginger and lemon in a pressure-rated bottle, pour in the strained liquid leaving 2 to 3 cm of headspace, and seal.
- +1-2 dLeave the bottle at room temperature for 1 to 2 days, briefly cracking the lid once a day to check the pressure, then refrigerate.
- ThenChill before opening, open slowly over a sink, and strain out the ginger and lemon as you pour.
Troubleshooting
What it may be good for
Keep the grains happy
Use water without chlorine, which harms the culture, and keep metal strainers and spoons away from the grains. Between batches they can rest in sugar water in the refrigerator, and a batch about once a week keeps them going.
It is not alcohol-free
A home batch usually holds around 0.5 percent alcohol or a little more, and in a British Columbia survey about one in five commercial water kefirs measured over 1 percent. A longer or warmer run means more.
What to watch out for
- Water kefir is a live, home-made drink that holds a little alcohol. If you are pregnant or nursing, have a weakened immune system, or have been told to avoid alcohol, check with your doctor first.
- Keep jars and utensils clean, use glass or food-grade plastic, and throw out a batch with dry, fuzzy mold or a rotten smell; sourness and foam are normal.
Water kefir is sugar water that kefir grains, small translucent clusters of bacteria and yeast, turn lightly sparkling and tart over a day or two. Lemon and ginger go into the bottle for a second round, giving a bright, peppery, citrus-sharp drink with no dairy and no tea.
Origin & Story
The grains look like crushed glass: pale, translucent, a little jelly-like, each one a colony of bacteria and yeast held together by a sugar chain that one of the bacteria, Lactobacillus brevis, spins around them. Feed them sugar water and a day or two later you have a lightly fizzy drink. The grains multiply as they work, so a jar becomes a gift to pass on.
No one can say where the grains began. Over the years they have been called tibicos, tibi, sugary kefir, Japanese water crystals and California bees, among other names. Most accounts point to Mexico, where tibicos is still a name for them: in 1899 a researcher named Lutz reported grains taken from the pads of a prickly pear cactus, and similar crystal-like grains are said to form on the fruit of the plant. A theory from 1889, that British soldiers carried the grains home from the Crimean War, was dismissed as unsupported three years later.
The chemistry is quick. In a lab study of water kefir, the sugar was used up in about a day, and over three days the pH fell from about 4.3 to about 3.5, which is why the drink swings from sweet to tart so fast. That is also why lemon and ginger go in at the end: a short second stage in a sealed bottle gives the fizz, and a little zest and spice finish the flavor.
Dissolve 50 g of sugar in 900 g of cool, non-chlorinated water, add about 50 g of hydrated water kefir grains, and leave the jar covered for 24 to 48 hours at 20 to 25°C; strain the grains out with a plastic strainer, bottle the liquid with 10 g of sliced ginger and the zest and juice of half a lemon per liter, leave it sealed 1 to 2 days at room temperature, and chill.

How much caffeine is in Lemon Ginger Water Kefir?
Lemon Ginger Water Kefir is naturally caffeine-free, so one serving, 8 oz cup (240ml), contains no measurable caffeine.
What temperature should I use for Lemon Ginger Water Kefir?
Keep it at a steady 25°C (77°F), out of direct sunlight. Warmer rooms ferment faster and taste more sour; cooler rooms slow everything down.
How long does Lemon Ginger Water Kefir take to make?
Timing: 24-48 hours in the jar, then 1-2 days in bottles. Method: Glass jar, then pressure-rated bottles. Ratio: 50 g kefir grains and 50 g sugar per liter, plus lemon and ginger in the bottles. Grind or leaf format: Hydrated whole grains and fresh ginger.
Why does my Lemon Ginger Water Kefir taste bitter?
A bitter or harsh note in a cultured drink usually comes from an ingredient that was scorched, over-spiced or not washed well, such as burnt bread or fruit skins, or from letting it run past its peak. Taste early and chill it as soon as it is pleasantly tart. Sharp, vinegary sourness is a different problem: it means it ran too long or too warm.
Is water kefir the same as milk kefir?
No. Milk kefir grains live on the lactose in milk and look like small cauliflower florets, while water kefir grains live on sugar water and look like translucent crystals. The two cultures are not interchangeable, and water kefir contains no dairy.
Why is my water kefir not fizzy?
Most of the fizz comes from the second stage in a sealed bottle, so leave it 1 to 2 days at room temperature in a pressure-rated bottle. Chlorinated water, metal tools or too little sugar slow the grains, and new grains may need a batch or two to settle in.
Who should avoid Lemon Ginger Water Kefir?
Water kefir is a live, home-made drink that holds a little alcohol. If you are pregnant or nursing, have a weakened immune system, or have been told to avoid alcohol, check with your doctor first. Keep jars and utensils clean, use glass or food-grade plastic, and throw out a batch with dry, fuzzy mold or a rotten smell; sourness and foam are normal.
