In India, Iran war forces Diet Coke to roll out a bigger can, heftier price tag

Unlike most other markets, Diet Coke is sold mostly in cans in India, making it more vulnerable to disruptions. Its most popular variant in India is the 300-milliliter can, priced at 40 Indian rupees (41 U.S. cents).

Coca-Cola has now rolled out 330-ml cans of Diet Coke in India for 50 Indian rupees, as the smaller ones are in tight supply, the sources said, adding the decision was made to account for higher costs.

On a per-ml basis, the price increase translates to 13.6%.

Coca-Cola, which has not publicly unveiled pricing changes, did not respond to multiple requests for comment.

At least one of the company's Indian bottlers has for a limited time started offering Diet Coke in small 200-ml glass bottles, though they are much more expensive than the canned drink, according to online listings and a third source with direct knowledge of the matter.
