In 1914, the London brewer Whitbread & Co. claimed it was the “largest beer bottler in the world.” Arguably it was, it having a network of more than forty bottling depots and stores in Britain and Belgium, with a dozen bottles available anywhere in Britain for 2/6. This chapter shows how Whitbread’s market-leading position in the bottled beer segment between 1869 and 1914 was dependent on various factors. The company’s message about the purity and quality of bottled beer remained steadfast throughout the period; it also invested in production and, as the business grew, a system of management. Most significantly, integration into distribution and the creation of the bottling network reduced the risk of adulteration by controlling the product from brewery to retailer, allowed it to be responsive to changes in demand, and reduced costs. Consequently, Whitbread’s beer was consistent in all respects: in purity, quality, availability, and price.
