Can coffee grounds be soaked in water for drinking

It is not recommended to directly soak coffee grounds in water for drinking. Coffee grounds are the residue left after coffee extraction, containing small amounts of caffeine and oil, which may irritate the gastrointestinal tract and affect taste. If you need to use coffee grounds, it is recommended to use other methods such as composting or deodorization. Soaking coffee grounds in water may cause discomfort. The coffee grounds have rough particles, and after brewing, they have a bitter taste with a residue sensation, which can easily irritate the mouth and throat when consumed. Although the residual caffeine concentration in coffee grounds is lower than that in coffee liquid, sensitive individuals may still experience palpitations or insomnia. The residual oil on the surface of coffee grounds may float on the water surface after being brewed with hot water, and long-term intake may increase digestive burden.

Caution should be exercised when using small amounts of coffee grounds in special circumstances. In a very small number of regions, there is a traditional process of using roasted coffee grounds for tea drinks, but it requires high-temperature sterilization and fine filtration. Improper storage of coffee grounds can easily breed mold, and direct brewing may pose a risk of microbial contamination. People who are allergic to caffeine or have weak gastrointestinal function may experience abdominal pain or acid reflux symptoms after drinking.

When handling coffee grounds in daily life, it is recommended to prioritize environmentally friendly uses. Mixing dry coffee grounds with soil can be used as a plant fertilizer, and its nitrogen-containing substances help improve soil quality. Coffee grounds can also absorb refrigerator odors. Simply put them in a breathable cloth bag and place them in a corner. If you want to consume coffee ingredients, choosing freshly ground coffee powder for brewing is safer and healthier, and it is also important to note that daily caffeine intake should not exceed 400 milligrams.
