A bottle of Pepsi generates revenue for multiple parties, and it's difficult to say who makes the most money without a detailed analysis of the specific costs, margins, and pricing strategies of each party involved.

However, generally speaking, the largest profit margins tend to be made by the retailer who sells the product to the consumer. Retailers often mark up the price of products to cover their own costs and generate a profit, and in many cases, this markup can be significant.

It's worth noting that the manufacturer and other middlemen involved in the distribution chain also make a profit on each bottle of Pepsi, but the exact amount of profit can vary greatly depending on a number of factors, such as the cost of production, transportation, and marketing.
