Bodega still stocking Italian wine (4)
I believe the answer is:
asti
'italian wine' is the definition.
(I've seen this before)
'bodega still stocking' is the wordplay.
'stocking' indicates the answer is hidden within the clue (the answer is held or stocked by the clue).
'ASTI' is hidden in the letters of 'bodega still'.
(Other definitions for asti that I've seen before include "Sparkling wine named after an Italian Piedmont town" , "Source of fizz" , "Italian wine - (then change a letter for ...)" , "Piedmontese white wine" , "Italian product" .)
