Mineral Water !
I was in India in May & June, the hottest months in India so my tips would revolve around my OWN experiences there.Yes, mineral water !Most important for me.Always check if the cap is properly sealed.Normally no problem but occasionally we would find that seals were broken off & the plastic bottles could be filled in with tap water !Any brand would do, normally priced at Rs 10 or Rs 12 (around the touristy places).It's pretty easy to find cold mineral water but in some areas, the weather was so hot even the mineral water was warm.Politely ask for a cooler one & they would let you choose.
