What is the term that defines having to do with the sense of taste?

What is the word used to describe having to do with the sense of taste? As in, olfactory is used to describe having to do with the sense of smell, auditory is used for hearing, tactile is used for touch/feel, and visual is used for sight. But I can't seem to find a term that defines having to do with the sense of taste. Does anyone know? And if any of these terms are wrong, pleases correct me. Thanks.
