Caffeine Myth – Does Roast Level Matter?

"Caffeine Truth: Light Roasts Have More (And Why It Doesn't Matter)"
The caffeine myth persists: "Dark roast = more caffeine." Wrong. Light roasts retain slightly more caffeine because roasting breaks down caffeine molecules. However, the difference is negligible (~0.06%). What matters more? Bean origin, brew method, and cup size. Learn what actually affects your coffee's kick.
Caffeine Truth: What Actually Affects Your Coffee's Kick
| Factor | Impact on Caffeine | Notes |
|---|---|---|
| Roast Level | Minimal (~0.06% difference) | Light retains slightly more |
| Bean Origin | Moderate (varies by variety) | Robusta > Arabica |
| Brew Method | High (extraction time) | Espresso < French Press |
| Cup Size | High (volume) | Larger cup = more caffeine |
| Grind Size | Moderate (surface area) | Finer grinds extract more |
Key Takeaway: Roast level has minimal impact on caffeine. Focus on brew method, cup size, and bean origin for the caffeine kick your customers want.
