Combine all ingredients for the base ginger juice in a heavy bottomed sauce pan on low heat.
When the sugar has dissolved, taste the juice and adjust as needed-I usually end up adding a little more ginger and lemon, but trust your own taste buds!
Remove from the heat and cool to room temperature
Meanwhile, prepare your sanitized swing top bottles and a funnel with a filter
To each swing top bottle, add the cooled ginger juice, leaving about 5 inches of space at the top
Add 2 tablespoons of ginger bug liquid to the bottle, leaving a few inches of head space at the top
Repeat until you run out of juice or bottles
Rest on the counter for a few days until fizzy-I like the check every day for carbonation. This will take 1-3 days
Once fizzy, place in the fridge until ready to drink
Enjoy with a slice of lime, in a mocktail, or simply over ice
