Denied win, unwind in rugby playing, wine producing region (8)
I believe the answer is:
burgundy
'wine producing region' is the definition.
(French wine region)
'denied win unwind in rugby playing' is the wordplay.
'denied' is a deletion indicator (the word is denied some of its letters).
'in' indicates putting letters inside.
'playing' is an anagram indicator.
'unwind' with 'win' taken out is 'und'.
'rugby' is an anagram of 'burgy'.
'und' going within 'burgy' is 'BURGUNDY'.
(Other definitions for burgundy that I've seen before include "Reddish" , "Full-bodied red wine" , "French wine from ruby dung" , "Red wine region" , "French region, colour and wine" .)
