Could it be described as follows?
- When the grape/fruit flavor which normally dominates is suppressed through judicious blending such that it recedes into the background and serves as a foil to other previously unnoticed flavors and aromas (e.g., leather, smoke) which now not only can begin to make their presence better felt by being allowed to come to the fore, but can also go on to interact more fully in different combinations such that each new sip presents a slightly different sensory experience.
