I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">wine list datum</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for year that I've seen before include "1% of a century" , "Four seasons" , "Complete cycle of seasons" , "Time taken by a planet to orbit the sun" , "Twelvemonth" .)
