Love label linked with old wine-producing region (5)
I believe the answer is:
otago
'region' is the definition.
(I have seen 'distant region' mean 'otago' so perhaps 'region' could also mean 'otago')
'love label linked with old' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'label' becomes 'tag' (tag is a kind of label).
'linked with' says to put letters next to each other.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'o'+'tag'+'o'='OTAGO'
'wine-producing' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for otago that I've seen before include "New Zealand district" , "Where kiwis are found" , "NZ location" , "NZ province" , "Council region of New Zealand" .)
