Beer to mature in different ways (5)
I believe the answer is:
lager
'beer' is the definition.
(lager is a kind of beer)
'mature in different ways' is the wordplay.
'mature' becomes 'age' ('age' can be a synonym of 'mature').
'in' is an insertion indicator.
'different ways' becomes 'lr' (I am not sure about this - if you are sure you should believe this answer much more).
'age' inserted inside 'lr' is 'LAGER'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for lager that I've seen before include "Bottom-fermented beer" , "Effervescent beer" , "Light-coloured beer" , "Light beer needed" , "Regal kind of beer" .)
