4. Le titre alcoométrique volumique (TAV), aussi appelé degré alcoolique, est la proportion d'alcool, c'est-à-dire d'éthanol, dans une boisson alcoolisée. Ce titre est le rapport entre le volume d'alcool, à la température de 20 °C, contenu dans le mélange et le volume total de ce mélange à cette même température. L'unité utilisée pour exprimer le titre est le pourcentage volumique (% vol) ou degré (noté °). La recommandation R22 de l'Organisation internationale de métrologie légale (OIML), a pour objet de définir la manière de l'exprimer. Les valeurs extrêmes de cette mesure sont obtenues pour l'eau qui titre 0° et l'alcool pur 100°.
