Complex organic molecules (COMs) are molecules
with six atoms or more, including at least one
atom of carbon.
...
In a new study, Leiden University astronomers
Will Rocha, Harold Linnartz and their
colleagues used Webb’s Mid-Infrared Instrument
to explore the COMs ice signatures in two
protostars: NGC 1333 IRAS 2A and IRAS
23385+6053.

They were able to identify a variety of COMs
like ethanol (alcohol) and likely acetic acid
(an ingredient in vinegar).
...


The paper is here

and has an interesting menu of COMs ;)

Sounds reasonable. Acetic acid is what you get when your wine oxidizes.

You mean we found traces from a giant alien piss-up? https://i.etsystatic.com/7551608/r/il/0be537/3184905672/il_794xN.3184905672_sg7w.jpg

So that interstellar ice contained wine AND free oxygen
