We had so much fun busting coffee myths the first time, we couldn’t resist coming back for round two. Coffee culture is full of beliefs that sound true but don’t hold up under closer inspection. So, here are five more coffee myths we think it’s time to set straight.
Myth #1: Espresso Is the Strongest Coffee
Espresso is more concentrated per ounce, but a standard cup of drip coffee usually contains more total caffeine simply because it’s a larger volume.
Myth #2: Decaf Coffee Has No Caffeine
Decaf isn’t caffeine-free, it just contains much less. A typical cup of decaf has about 2–5 mg of caffeine compared to 95+ mg in regular coffee.
Myth #3: Dark Roast Has More Caffeine
Many people think dark roast coffee is more caffeinated because of its bold flavor. In reality, caffeine content changes very little during roasting, and if anything, lighter roasts retain slightly more caffeine by weight.
Myth #4: Coffee Goes “Bad” After a Few Hours
Brewed coffee can lose flavor and aroma over time, but it doesn’t suddenly become unsafe to drink. Storing it in an airtight container can help preserve taste for several hours.
Myth #5: Coffee Is Bad for Your Heart
Older studies suggested coffee could raise heart disease risk, but modern research shows moderate coffee consumption may actually benefit heart health due to antioxidants and anti-inflammatory compounds.
