Sampling time with sparkling Italian wine — no good (7)
I believe the answer is:
tasting
'sampling' is the definition.
('taste' can be a synonym of 'sample')
'time with sparkling italian wine no good' is the wordplay.
'time' becomes 't' (abbreviation).
'with' says to put letters next to each other.
'sparkling italian wine' becomes 'asti' (Asti is a type of sparkling wine).
'no good' becomes 'ng' (abbreviation).
't'+'asti'+'ng'='TASTING'
(Other definitions for tasting that I've seen before include "Savouring" , "event with wine" , "Sampling (food)" .)
