Origin

Coffee is a beverage made from the seeds that are roasted (beans) of the coffee plant. The beans are a popular and profitable international commodity. The coffee plants are evergreen woody shrubs that thrive in tropical climates. The majority of the world's coffee is grown in the Bean Belt, which includes the areas around the Tropic of Cancer and the Tropic of Capricorn.

The most well-known legend of coffee's beginnings began with the goat herder Kaldi in Ethiopia. He noticed that the bright red berries of certain coffee plants helped his goats become more energetic. Kaldi shared his findings with the abbot of a nearby monastery who made a drink out of the berries. The berries' energizing effects took off from there.

Presently coffee beans are made by two main varieties of Coffea plants: Arabica and Robusta. The latter is found mostly in Africa and Indonesia, and is usually cheaper than arabica. Apart from the major varieties, there are also smaller specialty beans that are a mixture of robusta and arabica. These beans are referred to as peaberries and are much more flavorful than standard beans.

When roasting, beans may lose moisture, which could result in them becoming bitter or stale. To prevent this from happening, it is essential to select only fresh, top quality beans for your coffee.

Flavor

The four components of flavor -acidity, bitterness sweetness, and saltiness -can be influenced by bean type, climate, and the method of processing. These components can be mixed in a variety of ways to create different flavors, ranging from sweet and fruity to nutty, and even smoky.

When coffee beans are exposed to heat, they react with amino acids within the seed, forming hundreds of unique aromatic compounds that alter the flavor profile of coffee beans. 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 flavor of coffee that is roasted reflects these compounds.

While the Maillard Reaction affects the overall flavor of a roast, nonvolatile or volatile compounds also contribute to the taste of coffee. Green beans, whether unroasted or not, can have a flavor that is fruity, floral, or earthy. Bitterness can be associated with roasts that are full-bodied and contain more caffeine. However, it can also be caused by improper processing or storage.

Flavored coffee beans have flavor oils on them which preserve the beans and add a certain flavor and aroma. The flavor oils are made up of chemicals and natural flavors, like chocolate, cinnamon, vanilla. The flavors bind to the beans through a special chemical compound called polyphenol.

Health Benefits

Coffee beans are an excellent source of potassium, magnesium, and B vitamins. They also provide a valuable source of antioxidants that help to prevent oxidative stresses (which can cause chronic diseases like cancer and atherosclerosis). The antioxidant chlorogenic acid that is found in coffee beans is particularly beneficial against obesity-related ailments, such as high cholesterol and diabetes.

Coffee is also a natural energy booster and helps people feel more alert and energetic. The caffeine in it stimulates neurochemicals in the brain, which improve mental vigilance and memory, increases cognitive function and helps to regulate blood sugar levels within the body. Studies have found that moderate consumption of coffee can help reduce the risk of developing Parkinson's disease and dementia, as well as improve mood, satisfaction energy, and concentration.

Anti-aging: The antioxidants found in coffee (including caffeine and chlorogenic acids) act as an natural moisturizer for the skin that increases cell turnover, as well as reducing the appearance of fine lines and wrinkles. They also possess UV-protection properties, filtering light and preventing sun damage to 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 also eases pain and inflammation, acting as a natural sedative and improving the effectiveness of medical pain killers. It also contains cafestol and Kahweol, two diterpene ester with lipolytic properties within the adipose tissue, thereby aiding in the fight against cellulite.

Caffeine

Coffee is one of the most sought-after drinks around the world and it has become integral to many morning routines. Coffee beans are actually seeds of a plant known as the coffee tree or cheaper coffee cherry. they contain the natural stimulant, caffeine. The caffeine content in coffee can vary depending on how it is roasted and prepared. It can also be brewed. There are some rules that can help you select the right coffee.

The average coffee bean has approximately 2 milligrams of caffeine per bean, but the exact amount varies dependent on the size of the bean and how darkly roasted it is. There is a popular belief that dark roasts have more caffeine than light roast ones, but this is not the situation. Dark roast coffee beans will have less caffeine than light roasts because of their smaller density. However the amount of caffeine remains the same.

A typical cup of coffee has about 95 milligrams (mg) of caffeine in it, but the recommended daily limit is 400 milligrams. If you're not sensitive to caffeine staying within this range will not cause any adverse consequences. Caffeine isn't harmful to those who aren't. However it is essential to be aware of how much caffeine you consume and be cautious about overdoing.
