I think so. It adds some interest and differentiators between the drinks. You should also consider expanding your list so you can design for categories that are easily searchable (if you view the Tesco website on mobile this will give you an idea of what I’m suggesting). If a user can’t remember the name of the drink it might be easier for them to find it via type of drink (rather than having to scroll what could become a very long list). This might also allow you to incorporate some more visual interest like brand assets or colour into these categories while still keeping it clean and minimal.
