I believe the answer is:
oenophile
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">wine connoisseur</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 oenophile that I've seen before include "grape nut" , "Drink lover" , "wine I enjoy" , "Lover of wine" , "Wine-lover" .)
