The shelf life of beer is a complex topic influenced by various factors. Unlike some beverages, beer does not necessarily “expire” in a way that makes it unsafe to consume. Instead, it degrades in quality over time. The duration of time before noticeable degradation occurs depends on the type of beer, its storage conditions, and its packaging.
Understanding the factors influencing beer’s shelf life is important for both consumers and retailers. Optimal storage can extend the enjoyment of the beverage. Historically, preserving beer quality was a major concern for brewers, leading to innovations in packaging and brewing techniques that impact longevity.
