Peel the orange and lime: Remove the outer skins of 1 orange and 1 lime.
Juice the base ingredients: Using your Nama juicer, juice 5 carrots, 2 apples, 1 pear, 1 peeled orange, and 1 peeled lime. You should yield approximately 600–700ml (2 ½ – 3 cups) of juice.
Prepare the fermentation jar: Roughly slice 10g of fresh ginger (leave out the ginger if you prefer) and quarter 1 apple and 2 oranges. Add these to a 1-litre (4¼ cups) jar.
Combine and ferment: Pour the freshly prepared juice into the jar over the prepared fruit and ginger. Close the lid tightly and leave the jar to ferment for 3–5 days.
Fermentation timing: At room temperature (20°C / 68°F), fermentation takes approximately 3 days. In cooler conditions, it may take up to 5 days.
Strain and bottle the soda: Once fermented, strain the juice and use a funnel to decant it into 1–2 swing-top lid bottles. Seal the lids securely.
Secondary fermentation: Allow the bottles to ferment for 3–7 days at room temperature, burping them daily to release carbon dioxide. Burp by opening the lid for 1–2 seconds.
Fermentation timing: Warmer environments speed up fermentation, while cooler environments slow it down. Monitor the carbonation and taste until it reaches your desired fizziness.
Refrigerate and enjoy: Once the soda is fizzy and to your liking, transfer the bottles to the refrigerator. The soda will keep for up to 1 week in the fridge.
