The humble coffee mug isn’t just a cup — it’s a daily ritual, a personality test, and sometimes, a small act of rebellion. From hand-thrown ceramics that cradle your morning to travel mugs that survive rush-hour chaos, your mug says more about you than your words do before caffeine hits. This guide breaks down design, material, and meaning — from heat retention science to the soul of sustainability. Because coffee isn’t just about the brew — it’s about the vessel that carries your calm. Choose wisely. Sip slower. And never underestimate the power of your coffee mug.
