Coffee: Introduction, Ingredients, Health Benefits, and Keynotes

Introduction

Coffee is one of the most popular aromatic beverages in the world, made from roasted coffee beans — the seeds of the Coffea plant.
Originating from Ethiopia and later popularized globally, it is cherished for its rich flavor, stimulating aroma, and energizing effects due to its caffeine content.

It is consumed in various forms — black coffee, espresso, cappuccino, latte, or cold brew — and is a central part of both daily routines and social culture worldwide.
