The source gives al-rīq wa-l-khamr as a comparison of tastes, an analytical example rather than a statement about permitted conduct. For touch it gives al-jild al-nāʿim wa-l-ḥarīr, smooth skin and silk.
Taste: a resemblance discerned by the tongue.
Touch: softness or smoothness discerned through contact.
Each sense reveals a different kind of property. One object may have many sensory qualities, but the classification should track the quality being compared rather than another incidental feature.
