coffee beans types beans are high in concentrations of specific compounds - including caffeine, and should be consumed in moderation. Find out more about this renowned seed.

Origin

The seeds that are roasted from the coffee plant are used to make coffee, a drink that is brewed. The beans are among the most popular, and profitable international commodities. Coffee plants are woody, evergreen plants that thrive in the tropical regions. The majority of coffee in the world is produced in the Bean Belt, which includes those areas that lie between the Tropic of Cancer and the Tropic of Capricorn.

The most popular story about the origin of coffee began in Ethiopia with a goatherder named Kaldi. He observed that his flock was particularly active after eating the bright red berries that were found in certain coffee plants. Kaldi shared his findings with the abbot of a nearby monastery, who made a drink out of the berries. The energy-boosting effect of the berries grew.

Presently, coffee beans are produced by two major varieties of Coffea plants: Arabica and Robusta. The latter is found predominantly in Africa and Indonesia and is usually less expensive than arabica. In addition to the main varieties, there are smaller specialty beans that are a mix of robusta and arabica. These beans are referred to as peaberries and have more flavor than standard beans.

During roasting, beans could lose their moisture, which can lead to them becoming bitter or stale. To avoid this, it is crucial to use only fresh, premium beans for your coffee.

Flavor

The bean's variety, temperature and processing method can influence the four components of taste -- acidity and bitterness, sweetness and saltiness. The amount of these components can create a wide variety of flavor profiles that range from fruity and sweet to nutty and even smoky.

When coffee beans are heated, they react with the amino acids in their seeds, forming hundreds of aromatic compounds that influence their flavor profile. This process is known as the Maillard Reaction and it is the same chemical reaction that occurs in nearly all cooking. The aroma of beans cooked reflect these compounds.

While the Maillard Reaction affects the overall flavor of roasts, nonvolatile and volatile compounds also contribute to the taste of coffee. The flavor of a green or unroasted bean may be earthy, floral, fruity, or chocolatey. Bitterness is typically connected with roasts with a fuller flavor that contain more caffeine, however it can also be due to improper brewing methods or storage.

Flavored coffee beans come with flavor oils that help preserve the beans and add a certain flavor and aroma. The flavored oils are a combination of natural and chemical flavors that can include everything from cinnamon to vanilla chocolate. The flavors are bound to the beans by the chemical compound polyphenol.

Health Benefits

Coffee beans are a great source of potassium, magnesium, and B vitamins. They're also a good source of antioxidants, which help to prevent the oxidative stress (which causes chronic diseases like atherosclerosis and cancer). The antioxidant chlorogenic acid that is found in coffee beans is particularly beneficial against obesity-related diseases, like the high cholesterol level and diabetes.

Coffee is a natural energy boost that helps people feel more alert. Caffeine stimulates neurochemicals, which enhances alertness, memory and cognitive function. It also helps control blood sugar levels. Studies have shown that moderate consumption of coffee can lower the risk of Parkinson's disease and dementia, and also boost mood, happiness as well as energy and concentration.

Anti-aging: The antioxidants (including caffeine and the chlorogenic acids) in coffee work as an natural moisturizer for skin, increasing cell turnover, which reduces wrinkles and fine lines. They also have UV-protection properties, filtering the sunlight and preventing sun-induced skin damage.

Anti-depressant Coffee beans can be used as an anti-depressant that boosts serotonin and dopamine in the brain to increase the amount of happy hormones. It also eases pain and inflammation, acting as a natural painkiller, and improving the effectiveness of prescription painkillers. Coffee also contains cafestol as well as kahweol which are diterpene esters with lipolytic qualities in the adipose tissue, thereby aiding in fighting cellulite.

Caffeine

Coffee is among the most popular drinks in the world and it has become a staple of many morning routines. Coffee beans are actually seeds of a plant known as the coffee plant or coffee cherry, and they contain the natural stimulant caffeine. The amount of caffeine in coffee can differ based on the method by which the bean is made, roasted, and brewed. There are some rules to help you select the best coffee.

The average coffee bean contains approximately 2 milligrams per bean. However the exact amount will differ depending on its size and how darkly it was roast. There is a popular belief that darker roasted beans have more caffeine in them than lighter roasted ones, but this is not the reality. Dark roast coffee beans contain less caffeine than light roasts due to their smaller density. However the amount of caffeine remains the same.

A typical cup of brewed coffee has around 95 milligrams caffeine in it, however the recommended daily limit is 400 milligrams. If you're not sensitive to caffeine staying within this limit will not cause any adverse consequences. If you're not sensitive to caffeine can still enjoy their coffee, but it's important to be aware of the amount of caffeine you're ingesting and avoid overdoing it.
