My brain organizes things as "beer, wine, and alcohol (aka spirits)" as opposed to "alcohol, including beer and wine". And an "alcoholic beverage" is just either a spirit alone or a spirit mixed with something.
Probably because that's how my state organizes the stores (with wine/alcohol in separate stores from beer, so if you say "we need to buy beer" that means going to a different place than "we need to by alcohol").
(FWIW I'm a native US English speaker.)
