Alcohol does not, in and of itself, contribute flavor to wine.
Answer: False.
Besides a feeling of fullness and roundness on the palate, alcohol contributes a slight sense of sweetness. For example, wines that are generally high in alcohol such as California zinfandels and Australian shirazes often have a slightly sweet flavor. That sweetness comes not just from the ripeness of the grapes, but also from the alcohol that was created during fermentation.
