What Are Coffee Beans?
The coffee beans you use to brew are actually seeds from the fruit called a coffee cherry. The coffee plant is perennial plant, which means that it is able to grow every year.
Coffee beans are high in concentrations of certain compounds - such as caffeine, and should be consumed in moderation. Learn more about this well-known seed.
Origin
The seeds that are roasted in the coffee plant are used to create a brewed beverage called coffee. The beans are among the most coveted and profitable commodities on the planet. Coffee plants are woody, evergreen plants that thrive in the tropical regions. The Bean Belt includes the areas surrounding the Tropic of Cancer, and the Tropic of Capricorn.
The most well-known origin story of coffee began in Ethiopia with a goatherder named Kaldi. He noticed that his herd became especially active after eating the bright red berries of some coffee plants. Kaldi shared his discovery with the abbot of a nearby monastery, who created a drink from the berries. From there, the energetic effect of the berries 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 more affordable than arabica. There are many smaller varieties that are a mixture of robusta and arabica. These beans are referred to as Peaberries and have a more flavorful taste than standard beans.
When roasting, beans may lose their moisture, which can lead to them becoming bitter or stale. To avoid this, it is crucial to select only fresh, high-quality beans for your coffee.
Flavor
The four components of flavor -- acidity, bitterness, saltiness, and sweetnessare influenced by bean type, climate, and the method of processing. These elements can be combined in a variety of ways to create different flavor profiles, from sweet fruity to nutty and even smoky.
When coffee beans are exposed to heat they react with amino acids present in the seeds, resulting in hundreds of unique aromatic compounds that impact their flavor profile. This process is known as the Maillard Reaction and it is the same chemical reaction that happens in nearly all cooking. The aroma of roasted beans is a reflection of these compounds.
The Maillard Reaction is responsible for the overall flavor, but volatile and nonvolatile compounds can also play a role in the taste of coffee. The taste of a unroasted or green bean could be earthy floral, fruity, or even chocolaty. Bitterness is often associated with roasts that are full-bodied and contain more caffeine. However, it could also be caused by improper processing or storage.
Flavored coffee beans contain flavor oils that help preserve the beans and provide a unique flavor and aroma. These flavored oils are a combination of natural and chemical flavors that range from vanilla to cinnamon to chocolate. The flavors bind to the beans using a chemical compound that is called polyphenol.
Health Benefits
Coffee beans are a good source of potassium, magnesium, and B vitamins. They are also a good source of antioxidants, which help prevent oxidative stresses (which can cause chronic diseases like atherosclerosis and cancer). The antioxidant chlorogenic acids found in coffee beans are especially effective against obesity-related diseases, such as diabetes or high cholesterol levels.
