Clean and hull the strawberries. Add 4 cups water, strawberries, ginger and maple syrup to the blender. Blend about 25 seconds, going from low to high speed.
Pour into a ½ gallon container. Add the remaining water, vinegar and basil. Stir.
Cover with a lid and a tea towel. Leave it at room temperature for 24 hours, then refrigerate overnight. The mix will get stronger in the fridge.
Strain and pour into glass bottles. Keep refrigerated up to two weeks.
Serve over ice.
Notes
Note: Resting at room temperature increases the probiotic content. You don't have to do this. You can blend and mix and serve right away or refrigerate right away. [nutrition-label]
