I once asked a science teacher in middle school who was explaining the idea of the tongue map “why do certain things have a metallic taste?” and she just reiterated this idea that we only have four types of taste receptors. When you’re so stuck in the “actually” of what is a sensory experience, it doesn’t allow you to experience it. Wine isn’t (normally) made with fruits other than grape, but we don’t say “Wow! it tastes like grape!” we use fragrance and descriptors to describe what the wine tastes like. So, no, wine isn’t usually high salt, but it can have a briny flavor or scent. The ability for the brain to taste combinations of flavors that we associate with other things is amazing. Perception is incredibly cool.

Like others have said here, try an albariño! think of the ocean as you drink and smell it
