Liqueur cheered Met men after storm (5,2,6)
I believe the answer is:
creme de menthe
'liqueur' is the definition.
(creme de menthe is a kind of liqueur)
'cheered met men after storm' is the wordplay.
'after' means one lot of letters go next to another.
'storm' indicates an anagram.
'cheered'+'met'+'men'='cheeredmetmen'
'cheeredmetmen' anagrammed gives 'CREME DE MENTHE'.
(Other definitions for creme de menthe that I've seen before include "alternative to 9 across [CHARTRESE] ?" , "booze" , "Green-coloured liqueur" , "Mint flavoured liqueur" , "Peppermint liqueur" .)
