Why is wine decanting necessary before drinking crusted wine?
Decanting was originally used for wine residue filtration and interference
elimination for wine appreciation. Moreover, during wine decanting, the
original odor of wine can gradually emanate and some aroma components in wine can
gradually diffuse to the air slowly mixing with the original odor. The
combination of original odor with secondary aroma can change the taste of wine.
Moreover, during decanting, such unpleasant odor substances as sulfur dioxide can
volatilize, amply bringing out the aesthetic perception of fruit.
