Some people when they have damage to their ears experience a change in taste.
This is because there are nerves, called the Chorda Tympani, which run from the taste buds at the front of the tongue, through the middle ear, and all the way to the brain where they carry taste messages. Sometimes when there is damage to the ear it can affect these nerves and the perception of taste.
