A toast?

Ars Technica has a light article about alcohol and astronauts. They include Aldrin's communion wine, though that doesn't seem in the same category as Christmas bottles of Coronet for Apollo 8.

In particular, carbonated options like champagne, beer, or a Tom Collins likely wouldn't be viable.

"Aesthetically, bubbles don't work the same," Stephenson said. "When prepared on Earth, bubbles are more buoyant, and they travel up. In space, there is no up, and they clump in the middle until disturbed. It kind of looks like a congealed mess.”

Beyond looks, the bigger issue would be how those bubbles work within astronauts. On Earth, as Stephenson pointed out, gravity helps keep what we ingest down. Gases then separate and rise, leading to burps. But in space, gases, solids, and liquids can intertwine without gravity to separate them. "You can't burp in space," he said. "Well, you can, but you'd probably throw up at the same time."

A cola would be equally unappetizing.
