Italian wine and meat retailed at first by American company (9)
I believe the answer is:
lambrusco
'italian wine' is the definition.
(I've seen this before)
'meat retailed at first by american company' is the wordplay.
'meat' becomes 'lamb' (lamb is a kind of meat).
'at first' indicates taking the first letters.
'by' means one lot of letters go next to another.
'american' becomes 'us' (abbreviation for United States).
'company' becomes 'co' (abbreviation).
The first letter of 'retailed' is 'r'.
'lamb'+'r'+'us'+'co'='LAMBRUSCO'
'and' acts as a link.
(Other definitions for lambrusco that I've seen before include "Medium sweet, semi-sparkling Italian red or white wine" , "Sparkling Italian wine" , "Type of Italian wine" .)
