A great leap up from some European wine store (4,5)
I believe the answer is:
pole vault
'a great leap up' is the definition.
'some european wine store' is the wordplay.
'some european' becomes 'pole' (Pole is an example).
'wine store' becomes 'vault'.
'pole'+'vault'='POLE-VAULT'
'from' is the link.
(Other definitions for pole vault that I've seen before include "Olympic field event" , "Athletic event" , "Sergey Bubka was world champion at this event" , "Field event -- value plot (anag)" , "High-flying Olympic event" .)
