Use this wild fermented ginger beer recipe is a baseline, try it as written the first time and then you can alter the flavour to your own preferences. Add more or less ginger or more or less sugar. Use a lemon instead of a lime, try a different type of sugar. It really can become your own . I use plastic bottles to store the final ginger beer as the fermentation process can lead to unexpected explosions. Tip: If you buy a couple of 1 litre bottles and a 500ml bottle of filtered water to start off with then just clean and reuse them as you go.
