Praise short quote describing wine (6)
I believe the answer is:
credit
'praise' is the definition.
(I've seen this before)
'short quote describing wine' is the wordplay.
'short quote' becomes 'cit' (I can't justify this - if you can you should give a lot more credence to this answer).
'describing' is an insertion indicator (describe can mean to form the outline of).
'wine' becomes 'red wine' (red is a type of wine).
'cit' enclosing 'red' is 'CREDIT'.
Can you help me to learn more?
(Other definitions for credit that I've seen before include "it's on the cards?" , "Acknowledgment, recognition or praise" , "entry in cashbook" , "Tick - distinction" , "Ascribe" .)
