Coffee itself wouldn't make your burps taste like gasoline, but it can contribute to digestive issues in some people, leading to more noticeable or unpleasant burps. The taste of burps is primarily influenced by the food and beverages consumed, as well as individual digestion. If you experience a gasoline-like taste, it could be due to other factors like acid reflux or certain foods, rather than coffee alone. If this is a regular occurrence, it might be worth consulting a healthcare professional.

Burps that taste like boiled eggs may be due to the presence of sulfur compounds in the digestive process. Foods high in sulfur, such as eggs, garlic, and certain vegetables, can lead to the production of hydrogen sulfide gas, which is responsible for the eggy flavor. Additionally, digestive issues or an imbalance of gut bacteria can exacerbate this taste. If the problem persists or is accompanied by other symptoms, it's a good idea to consult a healthcare professional.
