bubbly

Bubbly is an English term with several related meanings. As an adjective, it most often describes liquids that contain dissolved gas and produce visible bubbles, especially carbon dioxide, when opened or poured. In common usage, "bubbly" refers to sparkling or fizzy beverages such as soda, mineral water with carbonation, or sparkling wines and champagnes. The sensation is produced by CO2 coming out of solution; bubbles form at nucleation sites, rise to the surface, and contribute to the drink's mouthfeel and aroma release. Carbonation can be achieved by natural fermentation (as in many sparkling wines) or by injecting CO2 under pressure (forced carbonation). The amount of dissolved CO2 is often described in volumes; typical carbonated beverages range from about 2 to 8 volumes, depending on style.

In a social or literary sense, "bubbly" describes a person who is cheerful, energetic, and sociable. It can also be used to characterize events, environments, or performances that feel lively. The term is widely used in media, marketing, and everyday speech, sometimes as a positive attribute and sometimes as a light, playful descriptor.

In branding and product naming, "bubbly" or variants appear in references to sparkling water, wines, cocktails, and sweets to evoke effervescence. The word carries no fixed technical standard beyond its general association with gas and a light, fizzy quality.
