Make a mistake and throw out the drink (6)
I believe the answer is:
sherry
'the drink' is the definition.
(sherry is a kind of drink)
'make a mistake and throw' is the wordplay.
I cannot quite understand how this works, but
'mistake' could be 'err' (to err is to make a mistake or blunder) and 'err' is located in the answer.
'throw' could be 'shy' (shy is a kind of throw) and 'shy' is found in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'out' acts as a link.
Can you help me to learn more?
(Other definitions for sherry that I've seen before include "Fortified wine originally from Spain" , "Fortified wine as aperitif" , "Strong sweet wine as aperitif" , "Preprandial drink" , "Oloroso or amontillado?" .)
