The Spanish invested in wine for drinks cabinet.. (8)
I believe the answer is:
cellaret
'drinks cabinet' is the definition.
(a cellaret is a drinks cabinet)
'the spanish invested in wine' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'invested in' means one lot of letters goes inside another.
'wine' becomes 'claret' (claret is a kind of wine).
'el' placed within 'claret' is 'CELLARET'.
'for' is the link.
(Other definitions for cellaret that I've seen before include "place to store wine" , "Cabinet for drinks and glasses" , "From sideboard" , "Wine cupboard - all Crete (anag)" .)
