This Common Myth About Beer Expiring Is Totally Wrong — Scientists Just Got to the Bottom of It! When it comes to beer, one long-standing belief has stuck for decades: “Beer expires and goes bad after a certain date.” Whether checked on the bottle, labeled on the can, or simply ignoring use-by dates, many beer fans have shied away from enjoying their favorite brews past what they assume is their shelf life. But recent scientific research is shaking up that myth — and now, longtime brewers and science enthusiasts alike are stepping in to set the record straight. ### The Big Lie: Beer Expires Like Milk Most people assume beer spoils in a similar way to perishables such as milk or juice — meaning date labels and shelf-life claims are rigid rules. The idea is that hop compounds, alcohol content, and residual sugars signal rapid degradation over time, making beer unsafe or undrinkable after a few months or years. But new studies by microbial ecologists and food scientists have revealed a very different truth.
