Chop the unpeeled ginger into small pieces (do not peel, as the skin contains wild yeasts)
Add the water, ginger, and sugar to a clean glass jar
Stir vigorously to dissolve the sugar and introduce oxygen
Cover loosely with a cloth or lid and keep at room temperature
Every 24 hours, feed with 1 tbsp chopped ginger and 1 tbsp sugar
Stir well daily
Repeat daily until you see bubbles, a slightly yeasty smell, and fizz when stirred (usually after 3-5 days)
Once active, store in the fridge and feed once a week
Use the starter to create naturally carbonated soda by sealing it in a bottle to trap carbon dioxide
