The Retailers Who Started Making It ThemselvesNarrow moat

Private label has always existed in soft drinks and has always been dismissed, because the argument for Coca-Cola was never that it was the cheapest. What has changed is who is making it and how seriously. Walmart has launched cane-sugar sodas under its Great Value label and expanded its bettergoods range into beverages¹ — a retailer with unmatched scale treating soft drinks as a category to own rather than to stock.

The threat is not that consumers stop preferring Coke. It is structural. A retailer that manufactures a competing product controls the shelf on which both sit, decides the relative pricing, and captures the full margin on one of them. Coca-Cola's distribution moat — the arm's-reach-of-desire argument the moat pages describe — assumes the retailer wants the traffic Coca-Cola brings. That assumption weakens when the retailer has an alternative it earns more on.

Coca-Cola's defences are real: brand preference that survives price gaps, and a bottling system that services the shelf in ways a private-label supplier cannot match. Neither addresses the fact that the largest customer is now also a manufacturer.

Watch price/mix in North America specifically. Private label does not take share by winning arguments; it takes share by widening the price gap until brand loyalty stops covering it, and that shows up in realised price long before it shows up in volume.
