Put the wild blueberries into a blender jar.
Now add the water, it is good to have it a bit hot to help melt the frozen blueberries. If you let the blueberries thaw beforehand then just use room temperature water. Same if you are using fresh blueberries.
Add the stevia which is optional if you like this extra sweet.
Blend everything on liquefy until juicy.
Pour in glasses and serve the wild blueberry juice immediately.
