What Are Coffee Beans?

The coffee beans you use to brew are actually the seeds of the fruit called a coffee cherry. The coffee plant is a perennial, meaning that it returns every year.

Coffee beans contain high concentrations of specific compounds - including caffeine, which is why they should be consumed in moderation. Learn more about this renowned seed.

Origin

Coffee is a brewed beverage made from the seeds that are roasted (beans) of the coffee plant. The beans are a sought-after and profitable international commodity. Coffee plants are woody evergreen trees that are found in the tropics. The Bean Belt includes the areas that surround 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 from certain coffee beans in bulk plants helped his goats become more energetic. Kaldi shared his discovery with the abbot of a nearby monastery who brewed a drink using the berries. The energizing properties of the berries took off from there.

Currently, coffee beans are produced by two main varieties of Coffea plants: Arabica and Robusta. Robusta is predominantly in Africa and Indonesia, and is usually cheaper than arabica. There are also many smaller varieties that are a mix of arabica & robusta. These beans are referred as Peaberries and have a scrumptier taste than regular beans.

During roasting, beans can lose moisture, which could cause them to become stale or bitter. It is crucial to utilize fresh, high-quality beans for your coffee.

Flavor

The four components of flavor- acidity, bitterness, sweetness, and saltiness -are influenced by bean's type, climate and processing method. The level of these elements can produce a variety of flavor profiles that range from fruity and sweet to nutty, or even smoky.

When coffee beans are exposed to heat, they react with amino acids inside the seed, forming hundreds of aromatic compounds that alter their flavor profile. This reaction is referred to as the Maillard Reaction, and it is found in almost all cooking. The smell of beans that are roasted is a reflection of these compounds.

While the Maillard Reaction affects the overall flavor of a roast, nonvolatile or volatile compounds can also affect a coffee's taste. Green beans, whether unroasted or not, can have a flavor that is fruity, floral, or earthy. Bitterness is often associated with full-bodied roasts that contain more caffeine, but it can also be due to poor brewing methods or storage.

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

Health Benefits

Coffee beans are packed with a variety of nutrients that promote health including magnesium, potassium and B vitamins. They are also a good source of antioxidants that help to prevent the oxidative stresses (which can cause chronic diseases such as cancer and atherosclerosis). The antioxidant chlorogenic acid that is found in coffee beans is especially effective against obesity-related illnesses such as the high cholesterol level and diabetes.

Coffee is also an energy-boosting drink that is natural and helps people feel more energetic and alert. Caffeine increases neurochemicals, which improves alertness, memory and cognitive performance. It also helps regulate blood sugar levels. Drinking moderate amounts has been shown to reduce the risk of developing Parkinson's disease and dementia. It also boosts happiness, mood and energy levels as well as concentration.

Anti-ageing: The antioxidants (including caffeine and the chlorogenic acids) in coffee serve as natural moisturizers for the skin, boosting cell turnover, which reduces wrinkles and fine lines. They also have UV protection properties, blocking light and avoiding sun-induced damage to the skin.

Anti-depressant Coffee beans can be used as an antidepressant, boosting serotonin and dopamine in the brain to boost the levels of happy hormones. It also eases pain and inflammation, acting as a natural analgesic, and improving the effectiveness of pain killers. Cafestol and Kahweol are diterpene esters compounds that possess lipolytic properties. They can help reduce cellulite.

There is a widespread belief that dark roasted beans contain more caffeine in them than light roasted ones, but this is not the case. Dark roast coffee beans have less caffeine than light roasts due to their lower density. However, the amount of caffeine is similar.

The recommended daily limit for caffeine is 400 milligrams. A typical cup of coffee contains 95 milligrams.
