6 Common Coffee Myths—Debunked (The Truth Might Surprise You)

The world spins fast, and coffee myths have been spinning even faster.

Somewhere along the way, these myths about coffee found their way into our lives. Passed down like whispers, repeated without question: "Dark roast carries more caffeine." "Coffee dehydrates. "It stunts your growth or strains your heart." I'm sure you've heard them all and believed them like I did until one day, I paused… and began to wonder what was true. 

Well, FreshFields Coffee was founded on the belief that coffee moments should feel easy. We're all about simple joys, and in mornings that don’t ask for perfection, just presence.

So let’s exhale, slow the spin, and untangle a few of these myths together. Not with noise or jargon. But with honesty, and the kind of clarity that lingers long after the last sip. 

Myth 1: Dark Roast Has More Caffeine

The truth is, it doesn’t. In fact, it contains slightly less.

Dark roast tastes deep, smoky, and bold, but those flavors come from a longer roasting process, which gently lessens the caffeine. Light roast, in contrast, holds more of its natural energy. And while volume and weight can blur the lines a bit, if you’re measuring by grams, the caffeine difference is small, but real.

Take this with you: Light roast holds a little more spark. Dark roast carries the drama.

Myth 2: Coffee Dehydrates You

The truth? Coffee is like love, it gives more than it takes.

Yes, caffeine is a mild diuretic—but in moderate amounts, your cup still offers hydration. It’s mostly water, after all. And study after study reminds us that morning mugs are some of the best ways to show love to ourselves.

Take this with you: Your brew isn’t stealing from you—it’s helping fill the glass.

Myth 3: Coffee Stunts Your Growth

The truth: There’s no science behind the fear.

This one lingers from childhood warnings—softly spoken to keep little hands away from grown-up drinks. But, research finds no link between coffee and height, bone loss, or development.

Take this with you: Your height belongs to your DNA, not your drink.

Myth 4: Coffee Hurts Your Heart

The truth is, for many, it may do the opposite

Moderate coffee consumption—around 3 to 5 cups a day—has shown no increase in heart disease risk. In fact, coffee’s antioxidants may offer gentle support to heart health. But everyone is unique. If caffeine makes your pulse race, listen to that rhythm. And consult with a healthcare provider. 

Take this with you: For most, coffee and the heart can live in beautiful harmony.

Myth 5: Coffee Sober You Up

Here is the truth: It can’t undo what alcohol has done.

Coffee may help you feel more awake, but it won’t help your body process alcohol any faster. Alert doesn’t mean sober, and the danger lies in mistaking the two. If you've been drinking, time, not coffee, is your way home.

Take this with you: Coffee is clarity, not a cure. Let it hold space, not promises.

Myth 6: Freezing Beans Keeps Them Fresh

The truth: It can—if you treat them gently.

Freezing can preserve flavor, but only when done with care. Use airtight containers. Store in small portions. Avoid the dance of thawing and refreezing. When left exposed, your beans will lose their quiet magic to frost and air.

Take this with you: Freeze like you love them—sealed, slow, and with intention.
