What Are Coffee Beans? The coffee beans you use to brew are actually seeds from a fruit called a coffee cherry. The coffee plant is a perennial, which means it comes back year after year. Consuming coffee beans in moderation is recommended due to the fact that they contain high levels of caffeine as well as other compounds. Learn more about this well-known seed. Origin Coffee is a drink made from the seeds that have been roasted (beans) of the coffee plant. Beans are a well-known and lucrative international commodity. Coffee plants are woody, evergreen plants that thrive 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 starts in Ethiopia with a goatherder named Kaldi. He noticed that his herd became more active after eating the bright red berries of some coffee plants. Kaldi shared his findings with the abbot of a nearby monastery who brewed a drink using the berries. From there, the energizing effect of the berries grew. Currently coffee beans are made by two major varieties of Coffea plants: Arabica and Robusta. Robusta is mostly in Africa and Indonesia and is usually less expensive than arabica. In addition to the primary varieties, there are also smaller specialty beans that are a mix of robusta and arabica. These beans are called Peaberries and have a more delicious taste than standard beans. In the process of roasting beans lose their moisture, which could result in them becoming stale and bitter. To avoid this, it is essential to select only fresh, top quality beans for your coffee. Flavor The four components of flavoracidity, bitterness saltiness, and sweetness- are influenced by the beans' type, climate, and the method of processing. Coffeee of these elements can create a wide variety of flavor profiles ranging from fruity and sweet to nutty or even smoky. When coffee beans are exposed to heat they react with amino acids inside the seed, creating hundreds of aromatic compounds that alter the flavor profile of coffee beans. This process is known as the Maillard Reaction and it is the same chemical reaction that happens in almost all cooking. The result is that the smell of coffee that is roasted reflects these compounds. While the Maillard Reaction affects the overall flavor of a roast, nonvolatile or volatile compounds also influence the flavor of coffee. Unroasted or green beans can have a flavor that is fruity, floral, or earthy. Bitterness is typically associated with full-bodied roasts that contain more caffeine, however it can also occur due to improper brewing methods or storage. Flavored coffee beans are coated with flavor oils to help preserve the beans while providing an aroma and flavor. These flavored oils are a mixture of natural and chemical flavors that can include everything from cinnamon to vanilla to chocolate. The flavors attach to the beans by using the chemical compound polyphenol. Health Benefits Coffee beans are a fantastic source of potassium, magnesium, and B vitamins. They are also a good source of antioxidants that help to prevent the effects of oxidative stress (which can cause chronic diseases such as cancer and atherosclerosis). The antioxidant chlorogenic acid that is found in coffee beans is especially beneficial against obesity-related diseases, such as diabetes and high cholesterol levels. Coffee is also an excellent natural energy booster that helps people feel more alert and energized. Caffeine increases neurochemicals, which improves alertness, memory and cognitive function. It also helps to regulate blood sugar levels. Drinking moderate amounts of caffeine has been proven to decrease 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 are an natural moisturizer for skin, increasing cell turnover to reduce wrinkles and fine lines. They also have UV-protection properties, absorbing light and avoiding sun-induced damage to the skin. Anti-depressant: Coffee beans can be used as an anti-depressant which boosts dopamine and serotonin in the brain, which increases the levels of happy hormones. It also helps reduce pain and inflammation by acting as a natural painkiller, and increasing the effectiveness of painkillers. Coffee also contains cafestol as well as kahweol which are diterpene esters that have lipolytic properties in the adipose layer, aiding in fighting cellulite. Caffeine Coffee is a well-loved drink around the world. It is now an integral part of many people's morning routines. Coffee beans are the seeds of the coffee plant or the coffee cherry. They contain caffeine, which is a natural stimulant. The caffeine in coffee may differ based on how the bean is roasted, brewed and prepared. However, there are some basic rules about the amount of caffeine present in every coffee bean that will allow you to make informed choices when selecting your joe. The average coffee bean has about 2 milligrams of caffeine per bean. However, the exact amount can vary depending on its size and the intensity at which it has been roast. There is a common misconception that dark roasted beans contain more caffeine in them than light roasts however this isn't the case. A dark roast coffee bean has 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 contains about 95 milligrams of caffeine in it, however the recommended daily limit is 400 milligrams. Aiming to stay within this range will not cause any adverse side effects unless you are sensitive to caffeine. Caffeine is not harmful to those who are not sensitive. However it is essential to be aware of the amount of caffeine you consume and to avoid overdoing.
