String along with a top tasting pinot perhaps (5)
I believe the answer is:
twine
'string' is the definition.
(I know that string can be written as twine)
'along with a top tasting pinot perhaps' is the wordplay.
'along with' is a charade indicator (letters next to each other).
'a' becomes 'one'.
'top' means to remove the first letter.
'tasting pinot perhaps' becomes 'twi' (I am not sure about this - if you are sure you should believe this answer much more).
'one' with its initial letter taken away is 'ne'.
'ne' put after 'twi' is 'TWINE'.
Can you help me to learn more?
(Other definitions for twine that I've seen before include "wind" , "Curl; string" , "Tough string" , "Interweave" , "Garden string" .)
