Fruit drinks, just short, filled with ice (6)
I believe the answer is:
juices
'fruit drinks' is the definition.
(drinks made from fruit juices)
'just short filled with ice' is the wordplay.
'short' means to remove the last letter.
'filled with' is an insertion indicator.
'just' with its final letter taken off is 'jus'.
'jus' enclosing 'ice' is 'JUICES'.
(Other definitions for juices that I've seen before include "Liquid extracts, from fruit say" , "Liquids from fruit and vegetables" , "Liquids from fruits and vegetables, say" .)
