palate

A palate is what we use to taste food and drink.

When we talk about someone's palate, we're usually referring to their sense of taste. Some people might say they have a sophisticated palate, which means they can tell the difference between lots of different flavors and textures. This is because they've tried so many new foods and drinks that their senses are more sensitive. For example, if you take a foodie on a trip around the world, trying all sorts of exotic cuisine, their palate will become more refined over time.
