Ginger Beer
Ginger beer is my gateway ferment: you cultivate a 'ginger bug' (a wild-yeast starter, the soda equivalent of sourdough) over about a week, then use it to naturally carbonate a sweet ginger brew. Sanitize everything before it touches the culture — contamination is the only real way to fail.
Method
- 1
Build the bug (Days 1–7)
Each day, feed your jar a spoonful of grated ginger and a spoonful of sugar, stir, and cover with cheesecloth. Within a few days it should start bubbling and smelling yeasty — that's the wild yeast colony establishing. Take it a full 7 days to make sure the colony is healthy and vigorous before you brew.
- 2
Make the sweet ginger base
Simmer fresh ginger with sugar and water to make a strong sweet ginger tea, then cool it completely to room temperature. Anything still warm will kill the yeast you're about to add.
- 3
Pitch the bug & bottle
Strain in a good glug of active ginger bug and a squeeze of citrus, stir, and funnel into sanitized flip-top bottles, leaving headspace. The yeast eats the sugar and traps CO₂ — that's your carbonation.

Carbonate, then refrigerate
Leave bottles at room temp ~1–3 days, 'burping' one daily to gauge pressure. Once they're firm and fizzy, move them to the fridge to slow the yeast right down. Open cold and over a sink the first few times — wild ferments can get enthusiastic.
Notes
- Keep the mother bug going by feeding it ginger + sugar every few days; refrigerate it to slow feedings when you're not brewing.
- Sanitation is everything: jars, utensils, and bottles all get sanitized before use.
