Unraveling the evolving nature of gaseous and dissolved carbon dioxide in champagne wines: a state-of-the-art review, from the bottle to the tasting glass.
In champagne and sparkling wine tasting, the concentration of dissolved CO(2) is indeed an analytical parameter of high importance since it directly impacts the four following sensory properties: (i) the frequency of bubble formation in the glass, (ii) the growth rate of rising bubbles, (iii) the mouth feel, and (iv) the nose of champagne, i.e., its so-called bouquet. In this state-of-the-art review, the evolving nature of the dissolved and gaseous CO(2) found in champagne wines is evidenced, from the bottle to the glass, through various analytical techniques. Results obtained concerning various steps where the CO(2) molecule plays a role (from its ingestion in the liquid phase during the fermentation process to its progressive release in the headspace above the tasting glass) are gathered and synthesized to propose a self-consistent and global overview of how gaseous and dissolved CO(2) impact champagne and sparkling wine science.
