What Are Coffee Beans? The coffee beans that you brew are actually the seeds of an edible fruit known as a coffee cherry. The coffee plant is a perennial plant, which means that it comes back year after year. Coffee beans are high in concentrations of certain compounds – like caffeine, and should be consumed in moderation. Find out more about this popular seed. Origin The seeds that are roasted from the coffee plant are used to make a brewed beverage called coffee. The beans are one of the most well-known and lucrative commodities in the world. Coffee plants are woody evergreen plants that flourish in the tropics. The Bean Belt includes the areas around the Tropic of Cancer, and the Tropic of Capricorn. The most famous origin story of coffee began in Ethiopia with a goatherder named Kaldi. He discovered that the bright red berries from certain coffee plants stimulated his goats. Kaldi shared his discovery with the abbot of a nearby monastery, who brewed a drink using the berries. From there, the energetic effect of the berries grew. Presently, coffee beans are produced by two main varieties of Coffea plants: Arabica and Robusta. Robusta is mostly found in Africa and Indonesia and is generally cheaper than arabica. Apart from the major varieties, there are smaller, specialty beans that are a mixture of arabica and robusta. These beans are called Peaberries and have a scrumptier taste than standard beans. During roasting, beans could lose their moisture, which can lead to them becoming stale or bitter. To avoid this, it's important to use only fresh, premium beans for your coffee.

When coffee beans are exposed to heat they react with amino acids within the seed, forming hundreds of unique aromatic compounds that impact their flavor profile. This reaction is referred to as the Maillard Reaction, and it occurs in virtually all cooking. The result is that the flavor of roasted coffee is a reflection of these chemical compounds. The Maillard Reaction is responsible for the overall flavor, however volatile and nonvolatile compounds also contribute to the flavor of coffee. The taste of a fresh or unroasted bean could be earthy floral, fruity, or chocolaty. Bitterness is often due to roasts with a full body that contain more caffeine, but it could also be due to improper brewing methods or storage. Flavored coffee beans are coated with flavor oils to help preserve the beans and add the flavor and aroma. These flavored oils can be mixed with chemicals and natural flavors, including chocolate, cinnamon, vanilla. The flavors bond to beans with the help of an extremely chemical compound known as polyphenol. Health Benefits Coffee beans are a great source of magnesium, potassium and B vitamins.
