Which of the following is not one of the five established flavors?

The established flavors in the context of taste perception are typically identified as sweet, sour, salty, bitter, and umami. Floral is not classified as one of these five established flavors. Instead, floral notes are often associated with aromas and can be found in certain beers or food products, but they do not fit into the fundamental categories of taste. This distinction is important for understanding flavor profiles, as when discussing tastes, we focus on those that arise directly from the primary taste receptors on our tongues, rather than from aromatic compounds that contribute to the overall sensory experience.
