Are its wines on a scale that's unusual? (6)
I believe the answer is:
alsace
'are its wines' is the definition.
I can't judge whether this definition defines the answer.
'on a scale that's unusual?' is the wordplay.
'on' means one lot of letters goes inside another (as in clothing 'on' a person).
'that's unusual?' is an anagram indicator (I've seen 'unusual' mean this).
'scale' with letters rearranged gives 'alsce'.
'a' put inside 'alsce' is 'ALSACE'.
Can you help me to learn more?
(Other definitions for alsace that I've seen before include "Region of France famous for white wine" , "White wine; Fr. region" , "Region of northeastern France famous for its wines" , "Region of France, capital Strasbourg" , "Filled pastry" .)
