A little reason to celebrate

National Carbonated Beverage with Caffeine Day

Drink · November 19

A day for fizzy drinks with a caffeine kick, from colas and citrus sodas to sparkling coffees and energy drinks, and how people enjoy them.

National Carbonated Beverage with Caffeine Day falls on Thursday, November 19, 2026. That is 23 days away.

Carbonation and caffeine make an old partnership. One gives a drink its sparkle, the other gives it a little push, and together they fill a large share of the cooler at any gas station.

The category is wider than it first looks. Colas are the familiar center, built on caramel color, sweetness and a mix of spice and citrus flavors. Around them sit pepper-style sodas, some citrus sodas, sparkling teas, canned cold brew with bubbles, and energy drinks. Caffeine is naturally bitter, so it is part of the flavor too, not just the reason people reach for the can at three in the afternoon.

The fizz comes from carbon dioxide dissolved under pressure. Open the bottle and the pressure drops, the gas starts escaping, and the bubbles rise. Cold drinks hold their carbonation longer than warm ones, which is why a soda left on the desk goes flat faster than one in the fridge.

Most people mark the day simply, with a favorite can or a glass over ice. Some like a side-by-side tasting of a few colas to see whether they can tell them apart. Others revisit a regional soda they grew up with, the kind that only seems to exist in one part of the country and tastes best in a glass bottle.

Ways to celebrate

• Try a blind taste test of two or three colas with friends.
• Look for a regional caffeinated soda you have never tried.
• Compare the same drink from a can, a bottle and a fountain.
• Share a photo of your go-to afternoon fizzy drink.
