Origin

Coffee is a drink made from the seeds that have been roasted (beans) of the coffee plant. The beans are one of the most sought-after and profitable commodities on the planet. The coffee plants are evergreen woody shrubs that flourish in tropical climates. Most of the world's coffee is grown in the Bean Belt, which includes the areas surrounding the Tropic of Cancer and the Tropic of Capricorn.

The most popular origin story of coffee began in Ethiopia with a goatherder named Kaldi. He observed that the bright red berries of certain coffee plants stimulated his goats. Kaldi shared his findings with the abbot of a nearby monastery who brewed a drink using the berries. The energizing effect of the berries grew.

The coffee beans we have today come from two main varieties of the Coffea plant: Arabica and Robusta. Robusta is mostly in Africa and Indonesia and is typically cheaper than arabica. There are many smaller varieties that are a blend of arabica & robusta. These beans are known as peaberries and are much more flavorful than regular beans.

While roasting, beans can lose their moisture, which can result in them becoming stale or bitter. To avoid this, it is important to use only fresh, top quality beans for your coffee.

organic coffee beans of flavor -- acidity, bitterness, sweetness, and saltiness -can be influenced by variety of beans, the climate, and the method of processing. These components can be blended in a variety ways to create various flavor profiles, from sweet fruity to nutty, and even smoky.

When coffee beans are heated they react with the amino acids in their seeds to form hundreds of aromatic compounds that affect the flavor profile of the coffee. This process is called the Maillard Reaction and it is the same chemical reaction that occurs in nearly all cooking. The aroma of beans cooked reflect these compounds.

The Maillard Reaction is responsible for the overall flavor, however volatile and nonvolatile components also play a role in the flavor of coffee. The flavor of a unroasted or green coffee can be earthy, floral, fruity, or even chocolaty. Bitterness is often linked to full-bodied roasts that have more caffeine. However, it can also be caused by poor processing or storage.

Flavored coffee beans are coated with flavor oils that help preserve the beans while adding an aroma and flavor. These flavor oils are a combination of chemicals and natural flavors that can include everything from vanilla to cinnamon to chocolate. The flavors are linked to the beans by polyphenol, a chemical compound.

Caffeine

Coffee is one of the most sought-after drinks around the world, and it is now a part of the routine of many mornings. Coffee beans are actually seeds of a plant called the coffee plant or coffee cherry, and they contain the natural stimulant caffeine. The caffeine content in coffee varies based on the method of roasting, prepared and brewed. There are a few guidelines that can help you choose the right coffee.

The average coffee bean has approximately 2 milligrams of caffeine per bean, but the exact amount will differ dependent on the size of the bean and the amount of roasting it has. It is a popular myth that coffee beans that are darker roasted contain more caffeine than lighter roasted ones. This isn't the case. A dark roast coffee bean will have less caffeine in it than lighter roasts due to its lower density, however the overall amount of caffeine will be the same.

A typical cup of brewed coffee has about 95 milligrams (mg) of caffeine in it, however the recommended daily limit is 400 milligrams. Keeping within this range should not cause any negative side effects unless you are sensitive to caffeine. Caffeine does not cause harm to those who are not sensitive. However it is crucial to be aware of the amount of caffeine you drink and to avoid overdoing.
