A sheep fed cocoa, extremely hot drink (9)
I believe the answer is:
americano
'hot drink' is the definition.
(type of hot drink)
'a sheep fed cocoa extremely' is the wordplay.
'sheep' becomes 'merino' (breed of sheep).
'fed' is an insertion indicator (one word is 'fed' to another).
'extremely' means to remove the middle letters (only the extremes of the word are used).
'cocoa' with its middle removed is 'ca'.
'merino' going around 'ca' is 'mericano'.
'a'+'mericano'='AMERICANO'
(Other definitions for americano that I've seen before include "Espresso diluted with hot water" , "Style of coffee" , "drink" .)
