'one enjoying a drink' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'eats nuts in season' is the wordplay.
'nuts' indicates anagramming the letters (nuts can mean crazy).
'in' indicates putting letters inside.
'season' becomes 'winter' (winter is a season).
'eats' is an anagram of 'etas'.
'etas' inserted into 'winter' is 'WINETASTER'.
