I believe the answer is:
vintner
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">wine seller</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for vintner that I've seen before include "Wine producer" , "Wine merchant" , "one in red and white?" , "Wine seller" , "A wine-merchant" .)
