Wine store putting up mature old Burgundy principally (6)
I believe the answer is:
bodega
'wine store' is the definition.
(I've seen this before)
'up mature old burgundy principally' is the wordplay.
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'mature' becomes 'aged' (similar in meaning).
'principally' indicates taking the first letters.
The first letters of 'old burgundy' is 'ob'.
'aged'+'ob'='agedob'
'agedob' reversed gives 'BODEGA'.
'putting' is the link.
(Other definitions for bodega that I've seen before include "Small Spanish grocery and wine store" , "Spanish wine-shop" , "Spanish wine cellar" , "Wine-shop in a Spanish-speaking country" , "concern for alcohol" .)
