👉 Champagne fumes refer to the lingering aromas and odors that persist after the last sip of sparkling wine, particularly champagne. These fumes are primarily caused by the carbon dioxide bubbles trapped within the wine, which can leave a distinct, slightly effervescent, and sometimes floral or fruity scent on the tongue and in the nostrils. The intensity of these fumes can vary depending on factors like the type of grape used, the winemaking process, and how long the wine sits before being opened. While often considered a minor annoyance, champagne fumes are a charming byproduct of the bubbly's production and can add to the sensory experience of enjoying this luxurious beverage.
