Wine seller of new Tempranillo originating in grape-plant run (7)
I believe the answer is:
vintner
'wine seller' is the definition.
(I've seen this before)
'new tempranillo originating in grape-plant run' is the wordplay.
'originating' suggests taking the first letters.
'in' indicates putting letters inside.
'grape plant' becomes 'vine' (I've seen this before).
'run' becomes 'r' (cricket abbreviation).
The initial letters of 'new tempranillo' is 'nt'.
'nt' placed within 'vine' is 'vintne'.
'vintne'+'r'='VINTNER'
'of' acts as a link.
(Other definitions for vintner that I've seen before include "Wine seller" , "A wine-merchant" , "Wine merchant" , "Wine producer" , "one in red and white?" .)
