Acidic Difference Between Tea & Coffee Tea’s Acidity. Tea contains tannic acid, which becomes bitterer as the tea is steeped. Depending on the type, tea has a pH ranging from 4.0 to 6.0. Ginger tea and green tea are lowest in acidity. Many coffee manufacturers, like Puroast and Hevla, offer low acid coffee. Yunnan tea has a low acid level, as do ginger and green teas.

- As the acid becomes more concentrated, its boiling point will rise. Pure Sulfuric acid will boil at a temperature of 337 ºC (610 K, 639 ºF), whereas the more dilute the solution is, the closer its boiling point will be to that of water (100 ºC).

Chapter 9 â Grape Acids Grape juice and the must obtained from pressing are acidic, with a pH that generally ranges between 3.2 and 4.0. At harvest time, over 90% of grape acidity is due to malic acid and tartaric acid. Malic acid is very common in the plant kingdom and is found, for example, in apples, plums, and peaches.

Tea In regions of the world that prefer mild beverages, such as the West and Far East, green tea should be steeped in water around 80 to 85 °C (176 to 185 °F), the higher the quality of the leaves the lower the temperature. Regions such as North Africa or Central Asia prefer a bitter tea, and hotter water is used.

How to Brew Green Tea for the Health Benefits If the water is too hot or if the tea has been steeped for too long, it can impart bitterness. If the water is too cool, the full flavor of the tea won't be properly extracted. The ideal steeping time varies according to the size and shape of the leaves, the grade of the tea, and when the tea was harvested. Green tea is generally heated to 140 to 185 F and is brewed for one to three minutes. Several studies suggest that the brewing method can alter the catechin content of a cup of tea.
