What are the reasons for caffeic acid? what are the factors that affect the acidity of coffee?

Is the coffee acidic? Is that why I have nausea and acid reflux every day? Yes, coffee contains some acids, which play an important role in its flavor. Unfortunately, some of these acids can cause heartburn in some coffee lovers. A number of studies have shown that coffee relaxes your lower esophageal sphincter. This increases your likelihood of heartburn because it provides an opening for acid in the stomach to return to the esophagus.

In the United States alone, more than 15 million Americans suffer from heartburn every day. Therefore, avoiding your favorite drinks should not be the only solution to avoid acid reflux. After all, there are many ways to reduce Joe's acidity without affecting your health. What makes coffee acidic? When we talk about the acidity of coffee, we don't mean its sour taste.

In fact, the sour taste may be the result of a poor extraction process. Instead, we're talking about its pH value, which is usually about 5. The pH value of shallow baking is about 4.7. Coffee grounds contain more than 850 compounds that can give your favorite drink a unique aroma and taste.

During brewing, coffee releases about nine major acids. Some of these acids include palmitic acid, linoleic acid, acetic acid, quinic acid, chlorogenic acid, citric acid, malic acid and lactic acid. These acids play an important role in the acidity level and the unique flavor of coffee.

Factors affecting the acidity of coffee

The way it's baked.

The roasting temperature and duration can affect the acidity level of coffee. A study conducted by Joon-Kwan Moon et al. It is confirmed that the longer the roasting time of coffee beans is, the hotter the content of chlorogenic acid is. In addition, this study shows that shallow baking has higher acidity than deep baking.

Cold or hot brew

Many studies have confirmed that the acidity of cold brewed coffee is lower than that of coffee brewed in hot water. Brewing time will also affect the acidity of the drink, the shorter the brewing time, the more sour the coffee.

Coffee Grinding

The size of coffee grounds also plays an important role in the acidity of the drink. Because the larger ground has a smaller surface area relative to the volume, less acid is extracted in the brewing process. This means that when you use finer coffee powder, you can expect to produce more acidic coffee.

Coffee has low acidity in some parts of Asia and South America.

Many kinds of coffee from different parts of the world have different acidity. Therefore, choosing the right option can ensure that you drink a less acidic drink. In fact, in order to reduce the acidity of the product, some manufacturers use solvents or steam to process beans.

On the other hand, some coffee beans are naturally less acidic because of where they are planted. For example, coffee from the Caribbean, India, Brazil, Hawaii and Sumatra has lower acidity.

Deep-roasted coffee beans

Of all three kinds of roasted coffee, dark coffee has the lowest acidity. These dark bakes undergo many chemical changes, which reduce the acidity of the baking process. It is well known that the roasting process removes acid, so the more it is roasted, the lower the acidity of the coffee. Moderate and light baking can cause your stomach wall to secrete more acid than dark baking.

Coarse ground beans

For people who like to over-extract coffee beans, finely ground coffee beans are the best choice. Unfortunately, this also means that they extract more acid, resulting in highly acidic drinks. Therefore, in order to reduce the acidity of the drink, you should choose rough coffee.
