Question: how many litres of water does it take to make a bottle of coke?
Answer: Coca-Cola's water consumption As a result, a small 500 ml bottle of Coca-Cola takes roughly 1.9 litres of water to make (though Coca-Cola prefers to cite their own average figure from 2013 to the effect that each litre of Coke uses 1.29 litres of water).
