Cool Bordeaux bottles? One is blown (8)
I believe the answer is:
clarinet
'one is blown' is the definition.
I can't tell whether this defines the answer.
'cool bordeaux bottles?' is the wordplay.
'cool' becomes 'in' (I've seen this in other clues).
'bordeaux' becomes 'claret' (I've seen this before).
'bottles?' indicates putting letters inside ('bottle' can mean to contain).
'in' placed inside 'claret' is 'CLARINET'.
Can you help me to learn more?
(Other definitions for clarinet that I've seen before include "that works off wind" , "Wind instrument made from Clare tin" , "musician" , "Musical wind instrument as played by Benny Goodman" , "Woodwind instrument - Artie Shaw played one" .)
