At an Indian gourmet food store, Avanti Mehta is organizing a blind tasting of drinks sourced from France, Italy and India. No, this isn¡¯t wine, it¡¯s water.

Participants use tiny shot glasses to check the minerality, carbonation and salinity in samples of Evian from the French Alps, Perrier from southern France, San Pellegrino from Italy and India¡¯s Aava from the foothills of the Aravalli mountains.

¡°They will all taste different ... you should be choosing a water that can give you some sort of nutritional value,¡± said Mehta, who ?is 32 and calls herself India¡¯s youngest water sommelier, a term usually associated with premium wine. Her family owns the Aava mineral water brand.
