What Are Coffee Beans? The coffee beans you use to brew are actually seeds from an edible fruit known as a coffee cherry. The coffee plant is perennial, meaning that it will grow every year. Coffee beans contain high concentrations of certain compounds, such as caffeine, and should be consumed in moderation. Find out more about this well-known seed! Origin The seeds that are roasted in the coffee plant are used to create coffee, a beverage that is brewed. The beans are a popular and profitable international commodity. The coffee plants are evergreen, woody plants that thrive in tropical climates. The majority of the world's beans is produced in the Bean Belt, which includes the areas around the Tropic of Cancer and the Tropic of Capricorn. The most widely-known myth of coffee's history starts with the goat herder Kaldi in Ethiopia. He observed that his herd was particularly energetic after eating the bright red berries of some coffee plants. Kaldi shared his findings with the abbot of a nearby monastery who created a drink from the berries. From there, the energy-boosting effect of the berries spread. Currently coffee beans are produced by two major varieties of Coffea plants: Arabica and Robusta. The latter is primarily found in Africa and Indonesia and is generally less expensive than arabica. There are also many smaller varieties that are a blend of arabica & robusta. These beans are referred as Peaberries and have a more delicious taste than standard beans. During roasting, beans could lose their moisture, which can lead to them becoming bitter or stale. To avoid this, it's crucial to select only fresh, top quality beans for your coffee. Flavor The bean's type, climate and processing method can affect the four components of taste: acidity and bitterness as well as saltiness and sweetness. The degree of these elements can result in a variety of flavor profiles that range from sweet and fruity to nutty, or even smoky. When coffee beans are exposed to heat, they react with amino acids within the seed, creating hundreds of unique aromatic compounds that alter their flavor profile. This process is called the Maillard Reaction and it is the same chemical reaction that occurs in all cooking. The aroma of beans roasted is a reflection of these compounds. The Maillard Reaction is responsible for the overall flavor, however volatile and nonvolatile substances also contribute to the taste of coffee. Green beans, whether unroasted or not, can be a bit earthy, floral or fruity. Bitterness is typically connected with roasts with a fuller flavor that contain more caffeine, but it can also occur due to improper brewing methods or storage. Flavored coffee beans are coated with flavor oils that help to preserve the beans while providing an aroma and flavor. These flavor oils are a mixture of natural and chemical flavors that can include everything from vanilla to cinnamon to chocolate. The flavors stick to the beans with the help of the chemical compound polyphenol. Health Benefits Coffee beans contain a vast variety of health-boosting nutrients, such as potassium, magnesium and B vitamins. They also provide a valuable source of antioxidants that prevent the oxidative stress (which can cause chronic diseases such as cancer and atherosclerosis). The antioxidants found in the chlorogenic acids in coffee beans are particularly effective against obesity-related ailments such as diabetes and high cholesterol levels. Coffee is also an energy-boosting drink that is natural and helps people feel more energetic and alert. Its caffeine stimulates neurochemicals in the brain, improves the vigilance and memory, improves cognitive function and aids in controlling blood sugar levels within the body. Studies have found that drinking moderate amounts of coffee can help reduce the risk of Parkinson's disease and dementia, and also improve mood, satisfaction, energy and concentration. Anti-aging: The antioxidants in coffee (including caffeine and chlorogenic acids) act as a natural skin moisturizer increasing cell turnover and reduce the appearance of wrinkles and fine lines. They also have UV-protection properties, blocking sunlight and preventing sun damage to the skin. Anti-depressant Coffee beans can be used as an anti-depressant, boosting serotonin and dopamine in the brain to boost the level of happy hormones. It also eases inflammation and pain, acting as a natural painkiller and improving the effectiveness of medical painkillers. Cafestol and Kahweol are diterpene esters compounds that have lipolytic properties. They help to reduce cellulite. Coffeee is among the most loved drinks in the world, and it is now a part of many of our morning routines. Coffee beans are actually the seeds of a plant called the coffee plant or coffee cherry and they are a natural stimulant, caffeine. The caffeine content in coffee may differ based on how the bean is processed, roasted, and prepared. But, there are fundamental rules regarding the amount of caffeine in each coffee bean to allow you to make informed choices when selecting your joe. The average coffee bean contains approximately 2 milligrams in each bean. However the exact amount will vary depending on its size and the degree to which it has been roasted. It is a popular myth that coffee beans roasted in darker roasts contain more caffeine than lighter-roasted ones. This is not true. A dark roast coffee bean will contain less caffeine in it than a light roast due to its lower density, however the total amount of caffeine will be similar. The recommended daily limit for caffeine is 400 milligrams. A typical cup of coffee contains 95 milligrams. Keeping within this range should not cause any negative side effects unless you're sensitive to caffeine. People who aren't sensitive to caffeine can still enjoy their coffee, however it is important to be aware of the amount of caffeine you're inhaling and avoid overdoing it.
