Origin

Coffee is a drink made from the seeds that are roasted (beans) of the coffee plant. The beans are among the most sought-after and profitable commodities on the planet. The coffee plants are evergreen, woody plants that thrive in tropical climates. The Bean Belt includes the areas that surround the Tropic of Cancer, and the Tropic of Capricorn.

The most famous legend about coffee's genesis starts with the goat herder Kaldi in Ethiopia. He observed that his flock became especially active after eating the bright red berries of some coffee plants. Kaldi shared his findings with the abbot of a nearby monastery who made a drink out of the berries. The positive energy of the berries was spread.

Coffee beans today come from two major varieties of the Coffea plant: Arabica and Robusta. Robusta is found primarily in Africa and Indonesia and is generally cheaper than arabica. In addition to the main varieties, there are also smaller, specialty beans that are a mixture of arabica and robusta. These beans are known as peaberries and are much more flavorful than regular beans.

During the process of roasting beans lose their moisture which could result in them becoming stale and bitter. To prevent this from happening, it is essential to select only fresh, top quality beans for your coffee.

Flavor

The four components of flavor -- acidity, bitterness, sweetness, and saltiness -are influenced by beans' type, climate, and processing method. These components can be combined in a variety of ways to create various flavor profiles, from sweet fruity to nutty and even smoky.

When coffee beans are exposed to heat, they react with amino acids inside the seed, creating hundreds of unique aromatic compounds that impact their flavor profile. This process is called the Maillard Reaction and it is the same chemical reaction that occurs in nearly all cooking. The result is that the scent of coffee that has been roasted is a reflection of those compounds.

While the Maillard Reaction affects the overall flavor of the roast, nonvolatile as well as volatile compounds also influence a coffee's taste. The flavor of a unroasted or green coffee can be earthy, fruity, floral, or chocolaty. Bitterness can be a result of full-bodied roasts containing more caffeine. However, it could be caused by faulty brewing or storage.

Flavored coffee beans contain flavor oils on them that preserve the beans and provide a unique aroma and taste. The flavor oils can be mixed with chemicals and natural flavors, including chocolate, cinnamon, vanilla. The flavors are bound to the beans using polyphenol, a chemical compound.
