April 23

The Munich Reinheitsgebot, enacted on 23 April 1516, established strict regulations on beer ingredients within the Duchy of Bavaria. Mandating only water, barley, and hops, the law aimed to ensure quality, protect consumers, and stabilize grain supplies for bakers. It became one of history’s earliest food safety guidelines and shaped German brewing traditions. Over time, the Reinheitsgebot influenced beer production standards across Europe and remains synonymous with German beer purity. Modern brewers both honor and debate its legacy in craft brewing movements.

On April 23, 1985, The Coca-Cola Company unveiled New Coke, a reformulated version of its flagship soft drink designed to revive declining sales and compete with rivals. Despite positive initial taste tests, loyal consumers reacted with shock and disappointment, staging protests and campaigns demanding the classic taste. The backlash became a landmark marketing misstep and highlighted the deep emotional bond between consumers and the brand. Facing plummeting public approval, Coca-Cola reinstated the original formula as 'Coca-Cola Classic' on July 11, 1985. The episode remains a case study in brand management, demonstrating the risks of altering iconic products and the power of customer loyalty.
