What Are Coffee Beans? The coffee beans you use to brew are actually the seeds of the coffee cherry. The coffee plant is perennial, meaning that it is able to grow year after year. Coffee beans have high levels of certain compounds – like caffeine, so they should be consumed in moderation. Find out more about this well-known seed! Origin The roasted seeds of the coffee plant are used to make coffee, a drink that is brewed. The beans are a favored and lucrative international commodity. The coffee plants are evergreen woody shrubs that flourish in tropical climates. The majority of coffee in the world is grown in the Bean Belt, which includes those areas that lie between the Tropic of Cancer and the Tropic of Capricorn. The most widely-known myth of coffee's origin begins with a goat herder named Kaldi in Ethiopia. He observed that the bright red berries from certain coffee plants caused his goats to be more energetic. Kaldi shared his findings with an abbot of the nearby monastery who had made drinks using the berries. The energizing effects of the berries took off from there. Today, coffee beans come from two main varieties of the Coffea plant: Arabica and Robusta. The latter is found primarily in Africa and Indonesia, and is usually cheaper than arabica. In addition to the major varieties, there are many smaller specialty beans that are a mix of robusta and arabica. These beans are referred as Peaberries and have a scrumptier taste than standard beans. During roasting, beans can lose moisture, which could lead to them becoming stale or bitter. To avoid this, it's important to use only fresh, high quality beans for your coffee. Flavor The four components of flavor- acidity, bitterness, saltiness, and sweetness- are influenced by the bean type, climate, and the method of processing. The degree of these elements can create a wide variety of flavors that range from sweet and fruity to nutty or even smoky. When coffee beans are exposed to heat, they react with amino acids present in the seed, creating hundreds of aromatic compounds that alter the flavor profile. This process is called the Maillard Reaction and it is the same chemical reaction that occurs in nearly all cooking. The result is that the aroma of coffee that is roasted reflects these chemical compounds. The Maillard Reaction is responsible for the overall flavor, however volatile and nonvolatile compounds also contribute to the taste of coffee. The flavor of a unroasted or green bean may be earthy, fruity, floral or chocolaty. Bitterness is often associated with roasts with a full body that contain more caffeine. However, it can also be caused by improper preparation or storage. Flavored coffee beans have flavor oils which help preserve the beans as well as provide a unique flavor and aroma. These flavor oils are a combination of natural and chemical flavors that can include everything from vanilla to cinnamon to chocolate. The flavors bond to beans through a special chemical compound called polyphenol. Health Benefits Coffee beans are a rich source of a variety of health-boosting nutrients including potassium, magnesium and B vitamins. They're also an excellent source of antioxidants, which help to prevent the oxidative stress (which causes chronic diseases such as cancer and atherosclerosis). The antioxidant chlorogenic acid found in coffee beans is particularly beneficial against obesity-related diseases, like diabetes and high cholesterol levels. Coffee is also an energy-boosting drink that is natural that helps people feel more alert and energized. Caffeine stimulates neurochemicals, which enhances alertness, memory and cognitive function. It also helps regulate blood sugar levels. Drinking moderate amounts has been proven to decrease the risk of developing Parkinson's disease and dementia. It can also improve mood, satisfaction and energy levels, as well as concentration. Anti-aging: The antioxidants (including caffeine and the chlorogenic acids) in coffee act as natural moisturizers for your skin, boosting cell turnover to reduce wrinkles and fine lines. Coffeee have UV protection properties, which block sunlight and preventing sun-induced damage to the skin. Anti-depressant: Coffee beans can be used as an antidepressant that boosts serotonin and dopamine in the brain to increase the levels of happy hormones. It can also relieve pain and inflammation by acting as a natural painkiller and improving the effectiveness of medical painkillers. Cafestol and Kahweol are diterpene ester compounds with lipolytic properties. They help reduce cellulite. Caffeine Coffee is one of the most sought-after drinks around the world and has become a staple of many morning routines. Coffee beans are the seeds of the coffee plant, or the coffee cherry. They contain caffeine, which is a natural stimulant. The amount of caffeine in coffee is contingent on the method of roasting or prepared, as well as the method of brewing it. There are some rules that can help you pick the right coffee. The average coffee bean contains approximately 2 milligrams of caffeine per bean, however the exact amount will vary according to the size of the bean and the degree of roasting it has been. There is a common misconception that dark roasted beans contain more caffeine than light roasted ones but this isn't the reality. A dark roast coffee bean will have less caffeine than a light roast due to its lower density, but the overall amount of caffeine will be similar. A typical cup of coffee has about 95 milligrams of caffeine within it, however the recommended daily limit is 400 milligrams. Keeping within this range should not cause any negative unwanted effects unless sensitive to caffeine. People who aren't sensitive to caffeine can enjoy their coffee, but it's crucial to be aware of the amount caffeine you're inhaling and avoid overdoing it.
