Pliable wine connoisseur initially following the Spanish (7)
I believe the answer is:
elastic
'pliable' is the definition.
('elastic' can be a synonym of 'pliable')
'wine connoisseur initially following the spanish' is the wordplay.
'wine' becomes 'asti' (I've seen this before).
'initially' says to take the initial letters.
'following' is a charade indicator (letters next to each other).
'the spanish' becomes 'el' (**).
The initial letter of 'connoisseur' is 'c'.
'asti'+'c'='astic'
'astic' after 'el' is 'ELASTIC'.
(Other definitions for elastic that I've seen before include "capable of adapting to change?" , "Narrow band of rubber" , "Flexible (material)" , "Narrow strip of rubber" , "Springy, like a rubber band" .)
