Style of uplifting new beer (4)
I believe the answer is:
elan
'style' is the definition.
(I know that style can be written as elan)
'uplifting new beer' is the wordplay.
'uplifting' is a reversal indicator.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'beer' becomes 'ale' (type of beer).
'n'+'ale'='nale'
'nale' reversed gives 'ELAN'.
'of' is the link.
(Other definitions for elan that I've seen before include "Energy, style and enthusiasm" , "Stylishness" , "Dash in Paris" , "Dash, style" , "fizz" .)
