Mexico City artisan bar Casa del Agua has likely pulled off a world first by selling rainwater collected and filtered onsite in specially designed, reusable glass bottles.
Zenith International chair Richard Hall today noted the launch of the water, which has apparently been sold since 2012.
It's clearly a major customer draw, if the Casa del Agua Facebook page is anything to go by! It's also quite a business model. Clearly you'd need somewhere relatively pollution free with a high rainfall.
I'm not saying anything about Mexico City pollution levels - they appear to be quite high - but the water is clearly a seasonal product. Beyond June-October there's relatively little rain .
