There's one detail on coffee bags that tells you if it's worth buying

Most coffee bags display origin details and tasting notes, but one crucial piece of information often gets overlooked: the roast date. This single detail determines whether you're buying fresh coffee at its peak or stale beans that have been sitting on shelves for months.

To celebrate Tom's Guide Coffee Week, we're explaining why this simple check transforms your coffee experience. Fresh coffee tastes dramatically different from old coffee, with beans losing aromatic compounds and flavor complexity within weeks of roasting. Checking for a roast date takes seconds but ensures you're getting coffee worth drinking. The sweet spot for flavor and freshness is somewhere between two and four weeks after roasting. Here's what to look for and why it matters.
