Game and wine upset old solvers (6)
I believe the answer is:
hockey
'game' is the definition.
(hockey is a kind of game)
'wine upset old solvers' is the wordplay.
'wine' becomes 'hock' (hock is a kind of wine).
'upset' says the letters should be written in reverse.
'old solvers' becomes 'ye' (archaic pronoun for 'you' ie crossword solvers).
'ye' written backwards gives 'ey'.
'hock'+'ey'='HOCKEY'
'and' is the link.
(Other definitions for hockey that I've seen before include "Sport that uses curved sticks" , "Sport involving curved sticks, a ball and goals" , "It's played with curved stick" , "SPORT/GAME" , "Team game using curved sticks and ball" .)
