Washington Post, Them's Fightin' Words: War Lingo Rushes to the Front

[Laurence Horn]

Nice, but i trust we can assume that it wasn't the profusely cited
Allen Metcalf who contributed author Ken Ringle's authoritative
finding that "boozy" derives from "doughboys' experience with red
wine from Buzy, a French town near Chateau-Thierry, which also may
have spawned the term 'booze'."  Considering that there are several
19th-century OED attestations for "booz(e)"/"boose" (and one from
1732) and for "boozy" with different spellings dating back to 1529,
this history only works if you assume time travel.
