seltzer bottles

Seltzer bottles are offered in formats from small (~200 ml) bottles sold in multi‑packs up to single bottles and 1‑liter bottles. Examples found in listings include 4‑packs totaling 27.2 fl oz, single 33.8 fl oz bottles, and 1 L bottles.

Many listings advertise zero calories per serving and commonly use a 12 fl oz serving size. Serving counts vary by bottle; some product descriptions cite about three 12 fl oz servings for certain bottles.

Seltzers are packaged in both plastic and glass containers. Product details often specify plastic for some single bottles and glass for certain mixers sold in bottles.

Product listings and reviews generally describe these drinks as carbonated or sparkling with noticeable, satisfying fizz. Product bullets commonly label them "Carbonated" or "Sparkling."

Seltzers are frequently used as cocktail and mocktail mixers, serving as a base for classic cocktails, lemonades, light spritz‑style drinks, and other mixed beverages.
