Is it normal to have coffee grounds in coffee

It is normal to have coffee grounds in coffee. Coffee grounds are the residue of ground coffee beans, mainly composed of coffee powder particles, coffee oil, coffee fibers, and other components. During the coffee making process, coffee grounds may remain in small amounts due to incomplete filtration or different brewing methods.

When using non filter paper brewing methods such as press pot and Türkiye coffee pot, coffee residue residue belongs to normal process characteristics. This type of method uses metal filters or direct precipitation separation, which is difficult to completely filter fine particles, but can retain more coffee flavor substances. If the filter paper of hand brewed coffee is damaged or the water is injected too quickly, it may also cause a small amount of fine powder to penetrate the filter paper. The powder of espresso coffee is loose after high-pressure extraction, and occasionally very fine powder is mixed into the cup. When using precision filtration equipment such as siphon pots and drip filters, a large amount of coffee grounds may appear, which may be related to rough grinding or equipment failure. Excessive roasting of coffee beans can lead to structural fragility and produce more fine powder. Storing expired pre ground coffee powder can cause uneven extraction and increased residue during brewing due to oxidation and clumping. Drinking coffee containing trace amounts of coffee grounds usually does not affect health, but individuals with gastrointestinal sensitivity may experience discomfort. It is recommended to choose fresh freshly ground coffee beans, adjust the grinding degree according to the brewing method, and use double-layer filter paper or metal mesh to enhance filtration. After brewing, let the residue settle for a moment and avoid stirring the bottom of the cup when drinking. If there is an abnormal increase in coffee grounds or an accompanying odor, it is necessary to check the storage status of the coffee beans and the cleanliness of the utensils.
