There are lots of probiotic drinks but most are marketed as something really fancy or as sodas etc. This water would just be marketed as plain old water... with bacteria.

The bacteria could be personified and catoonized on the packaging for kids, or scientifically described and depicted with electron micrographs for adults.-- JesusHChrist, Feb 11 2016 Kambucha ?-- normzone, Feb 11 2016 Gesundheit.-- MaxwellBuchanan, Feb 11 2016 random, halfbakery
