Espresso smells like a rich, intense, and deeply roasted coffee scent. It's darker and more concentrated than regular coffee, with a bold, slightly bitter edge and a deep, caramel-like sweetness underneath. It's a powerful, wake-you-up kind of smell. Espresso smells like the inside of a busy coffee shop right when they're pulling a fresh shot, or the rich, bold coffee flavor in your favorite energy drink. It's used in fragrances to add a bold, dark, and energizing depth that makes a scent feel strong and sophisticated.
