Classification of Acids on Basis of source, Concentration Teachoo
The Key Acids. Several acids are present in high amounts in green coffee. They make up roughly 11% (by weight) of compounds in green coffee. Chlorogenic acids are by far the most common, followed by citric, malic and succinic acids. These are the products of the Krebs Cycle, an important chemical reaction responsible for releasing stored energy.
What Is Citric Acid?
Black coffee and black tea have almost identical levels of acidity, with coffee having an average pH of 4.5 - 6, and black tea having a pH of 4.9 - 5.5. Green tea, on the other hand, has an average pH of 10, making it 100,000 times less acidic than black tea. The brewing process also affects the acidity of coffee and tea.

Roasting decreases the amount of citric acid in arabica coffee but increases the amount of citric acid in robusta coffee (Fig. 4a). Green arabica has a higher amount of citric acid than green robusta, while the reverse is true for roasted coffee - roasted arabica has a lower concentration of citric acid than roasted robusta.
Citric Acid Benefits, Side Effects & Dosage
Citric Acid. Citric acid is the 2nd to 3rd highest organic acid found in coffee after chlorogenic acid. A typical medium roast will lose about 50% of its initial citric acid content and contributes to the bright acidity found in arabica coffee. It is extremely soluble in water and readily extracts into the cup at both ambient and hot temperatures.
