I worked for a B-School program which looked at growth opportunities for Cola in India.
One of the challenges were lack of electricity in large parts of the country. Even those who had electricity did not get it for 24x7. Those who had it uninterrupted could not afford to buy a freezer. This prevented the whole appeal of cold drinks that are not cold. Coca Cola and Pepsi invested heavily in refrigeration technologies as they mass imported cheap fridges and offered them for free. But electricity being government controlled remains a luxury in India. Coca Cola and Pepsi did crazy things to solve this problem including creating tie ups with ice makers who supply ice slabs for special events to brine based coolers than can keep things cool for 12 hours.
The results however were stunning. From 2016 to 2020, India has doubled the per capita consumption of cola per year to around 88 bottles. I think it is fair to assume that the ceiling for this number is around 1500 bottles per year because both USA and Mexico consume that much soda. Given the income difference between both countries I think that is an upper bound.
USA has 30x of India's per capita income but only 20x more soda consumption. Which makes me think Indians are going to hit that 1500 bound much much sooner than expected.
Note:
Some of our research results were fascinating and counterintuitive.
People preferred Coca Cola because it was "healthy" to a locally produced freshly squeezed sugarcane juice. The reasoning was that while the juicer center does not even have a food department clearance and is unsanitary, people had more faith in soft drink manufacturers quality control. Ice mixed with sugar cane juice was often transported via two wheelers, kept on the road and smashed into smaller pieces with a hammer.
When people were convinced that the sugar cane juice was produced in extremely clean fashion people preferred it over coke and were willing to even pay more than coke.
Companies like Paperboat in India have come into existence from these sort of insights.
