Origin of Nicaraguan coffee beans

Caffeine: it has a particularly strong bitter taste and stimulates the central nervous system, heart and respiratory system. Appropriate amount of caffeine can also reduce muscle fatigue and promote digestive juice secretion. Because it promotes kidney function, it is diuretic and helps the body to expel excess sodium ions from the body. But eating too much can lead to caffeine poisoning.

Tannic acid: the boiled tannic acid will decompose into pyrouric acid, so the coffee that has been brewed for too long will taste worse.

Fat: the most important ones are acid fat and volatile fat.

Acidic fat: that is, fat contains acid, its strength will vary according to the type of coffee.

Volatile fat: is the main source of coffee aroma, will emit about 40 aromatic substances.

Protein: the main source of calories, the proportion is not high. Most of the protein in coffee powder will not dissolve out when brewing coffee, so the intake is limited.

Sugar: coffee beans contain about 8% sugar. After baking, most of the sugars are converted to caramel, which browns the coffee and combines with tannins to produce sweetness.

Fiber: the fiber of raw beans will be carbonized after baking and combine with caramel to form the hue of coffee.

Minerals: contains a small amount of lime, iron, phosphorus, sodium carbonate and so on.

Roasted coffee beans

Peeling

Remove the peel and most of the flesh by mechanical, manual, or other means.

Ferment

By removing the mucus and film outside the core by fermentation, each manufacturer has its own fermentation time because the length of fermentation time will affect the flavor of coffee.

Drying

The drying method is mainly divided into natural sun drying and natural air drying. Too high water content can easily cause mildew and worms of raw coffee beans. High water content can also cause high acidity of coffee.

Baking

Through roasting, raw coffee beans can release the special aroma of coffee, and each coffee bean contains its aroma, sour taste, sweetness and bitterness.

From raw beans, light roasting, medium roasting to deep roasting, the water is released again and again, the weight is reduced, but the volume slowly expands, the color of the coffee beans deepens, the fragrant oil is gradually released, and the texture becomes crisp. In raw beans, there is a lot of chloric acid, which disappears with the baking process, releasing familiar and pleasant fruit acids such as acetic acid, citric acid and malic acid in wine.

Shallow baking: when the beans make the first light sound, the volume expands at the same time, and the color changes to a delicious cinnamon color. Acidity dominates the flavor of shallow roasted beans, texture and taste have not been brought into full play, generally used as canned coffee.

Medium roasting: coffee beans show an elegant brown color. This method of baking is also called city roast. Medium roasting can not only preserve the original flavor of coffee beans, but also moderately release aroma, so the blue mountains of Jamaica, Colombia, Brazil and other individual coffee, more choose this roasting method. At 20 minutes, the oil began to surface, and the beans were burned into a bright dark brown, called full-city roast, when the sour, sweet and bitter taste of the coffee reached the perfect balance.
