- How much alcohol will be in it?
- Due to the short fermentation, very little (approx. 0.5-1%), similar to kefir. If left longer, alcohol content can increase.
- Can the bottle explode?
- YES. The gases produced exert huge pressure. Use a plastic bottle as a tester (if hard, it's ready), or 'burp' the bottles daily.
Homemade Ginger Beer (Fermented)
Homemade ginger beer takes us back to a time when soft drinks were made from real, living ingredients, not in a laboratory. This is a naturally fermented, probiotic drink where yeast processes the sugar, creating fizzy carbonation and that characteristic slightly spicy flavour profile. The process itself is magic: sparkling life born from water and ginger.

Instructions
1
✓
Make ginger syrup: bring the grated ginger, sugar, and 500 ml water to a boil, then cook for 5 minutes. Let it stand until lukewarm.
Tip: The heat extracts the spicy gingerol compounds from the ginger and sterilises the base.
2
✓
Strain the lukewarm syrup into a large jug. Add the remaining 1 litre of water, lemon juice, salt, and yeast.
Tip: It is important that the liquid is below 30°C, otherwise the heat will kill the yeast. The lemon juice creates an acidic environment that yeast loves but harmful bacteria do not.
3
✓
Stir until the yeast dissolves, then fill into clean, pressure-resistant bottles. Leave 3-4 cm of empty space at the neck!
Tip: The headspace is essential so the generated gases have somewhere to expand before dissolving into the liquid (carbonation).
4
✓
Seal and place in a dark, room-temperature spot for 24-48 hours.
Tip: Fermentation happens here: the yeast eats the sugar and produces carbon dioxide in return (anaerobic process).
5
✓
Check the pressure (by squeezing a plastic tester bottle). When ready, refrigerate until consumption.
Tip: The cold slows down the yeast activity, stopping excess pressure buildup.
