Why Is My Urine Sour? Causes & What It Means

The main thing that makes urine taste sour is the presence of concentrated waste products in the urine, particularly uric acid. When the urine is concentrated, these waste products can provide the urine with a sour, acidic taste. Additionally, the presence of certain medications or foods, such as asparagus, can also alter the taste of urine, making it more sour.
