Coffee acidity and sweetness the principle of pressure coffee extraction by hand brewing coffee
Sweetness and sour A consensus about sweetness and sour is that sour and sweet complement each other. Sweet without sour will appear dull, while sour without sweet will be sharper. As the saying goes, sweet and sour and delicious, this is the truth. In terms of molecular polarity, due to the short extraction time, the sweet substances extracted by the hand filter droplets are usually less than the method pressure, and considering the contact with water caused by the degree of grinding.

Bitterness: caffeine is the best known bitter ingredient in coffee, but caffeine actually accounts for up to 10% of the bitter taste. This can be understood from the fact that the concentration of caffeine in roasted beans is not affected by the degree of roasting, and that non-caffeine also tastes bitter. So where does the remaining 90% of the bitterness come from? One of the sources of coffee bitterness is brown pigment. Brown pigment

Analysis of Acid components in Coffee decomposition of caffeic Acid in Coffee beans
The acidity of coffee is usually considered to be related to the quality of coffee. Acidity is typical of high-value coffee in Central America and East Africa. Excessive sour taste is considered to be the disadvantage of coffee. Acidity is related to growing at very high altitudes and mineral-rich volcanic soils. The acidity of washed beans is higher than that of sun-dried beans. For example, the concentration of sun-dried beans is heavier than that of washed beans, because the concentration obscures the acid of coffee.
