The coffee plants are evergreen woody plants that thrive in tropical climates. The majority of the world's beans is grown in the Bean Belt, which includes the areas around the Tropic of Cancer and the Tropic of Capricorn.

The most famous legend about coffee's beginnings starts with a goat herder named Kaldi in Ethiopia. He noticed that his herd became extremely energetic after eating the bright red berries that were found in certain coffee plants. Kaldi shared his discovery with the abbot of a nearby monastery who brewed a drink using the berries. The berries' energizing effects took off from there.

Currently coffee beans are produced by two major varieties of Coffea plants: Arabica and Robusta. Robusta is most commonly found in Africa and Indonesia and is generally more affordable than arabica. Apart from the major varieties, there are many smaller specialty beans that are a mix of arabica and robusta. These beans are referred to as peaberries and are much more flavorful than standard beans.

During roasting, beans could lose their moisture, which can result in them becoming stale or bitter. To avoid this, it's essential to select only fresh, premium beans for your coffee.

Flavor

The four components of flavor -acidity, bitterness saltiness, and sweetnessare influenced by beans' type, climate, and processing method. The amount of these components can create a wide range of flavor profiles, ranging from fruity and sweet to nutty, or even smoky.

When coffee beans are heated they react with amino acids within the seed, creating hundreds of aromatic compounds that alter the flavor profile of coffee beans. This reaction is known as the Maillard Reaction, and it occurs in virtually all cooking. The result is that the aroma of roasted coffee reflects those chemical compounds.

While the Maillard Reaction affects the overall flavor of roasts, nonvolatile and volatile compounds can also affect the flavor of a coffee. Green beans, whether unroasted or not, can have a taste that is sweet, floral or earthy. Bitterness is usually related to roasts that are full-bodied and contain more caffeine, however it can also be due to poor brewing methods or storage.

Flavored coffee beans are flavored with flavor oils on them which preserve the beans and add a certain flavor and aroma. The flavor oils are made up of chemicals and natural flavors, such as chocolate, cinnamon, vanilla. The flavors are attached to the beans using the chemical compound polyphenol.
