Coca-Cola has been consumed through two World Wars, the Great Depression, the Cold War, the 2008 financial crisis, and COVID-19. In every crisis, discretionary spending collapsed — except the small daily pleasure of a cold Coke. This is what 'consumer staple' means in practice: the tax keeps being collected regardless of what happens in the world.
Coca-Cola's moat rests on unparalleled global brand equity, a franchise bottling network covering 200+ countries, and concentrate pricing power that generates ~65% of revenue at high margins. The asset-light refranchising strategy (India, Philippines, Africa) further concentrates value in intangible assets—$13.5B trademarks and $18.7B goodwill—while reducing capital intensity.
