Meal and wine served up outside hostelry (6)
I believe the answer is:
dinner
'meal' is the definition.
(dinner is a kind of meal)
'wine served up outside hostelry' is the wordplay.
'wine' becomes 'red' (red wine is a kind of wine**).
'served up' shows that the letters should be reversed in order.
'outside' indicates putting letters inside.
'hostelry' becomes 'inn' ('inn' can be a synonym of 'hostelry').
'red' written backwards gives 'der'.
'der' enclosing 'inn' is 'DINNER'.
'and' is the link.
(Other definitions for dinner that I've seen before include "Main meal of day" , "serving in 20 [MESS] ?" , "What feeds" , "Repast" , "Supper" .)
