Composer, shortly after tea, gets a white wine (7)
I believe the answer is:
chablis
'a white wine' is the definition.
(I know that Chablis is a type of white wine)
'composer shortly after tea gets' is the wordplay.
'composer shortly' becomes 'bl' (I can't explain this - if you can you should give a lot more credence to this answer).
'after' means one lot of letters go next to another.
'tea' becomes 'cha' (cha is a type of tea).
'gets' becomes 'is' (I've seen this in other clues).
'bl' put after 'cha' is 'chabl'.
'chabl'+'is'='CHABLIS'
Can you help me to learn more?
(Other definitions for chablis that I've seen before include "Town in north central France noted for white Burgundy wines" , "Dry white Burgundy" , "French dry white wine" , "Burgundy town and white wine" , "Classic white wine from Burgundy" .)
