Drink containing very soft fruit (5)
I believe the answer is:
apple
'fruit' is the definition.
(I know that apple is a type of fruit of Maloideae)
'drink containing very soft' is the wordplay.
'drink' becomes 'ale' (type of beer).
'containing' means one lot of letters goes inside another.
'very soft' becomes 'pp' (musical abbreviation for pianissimo).
'ale' going around 'pp' is 'APPLE'.
(Other definitions for apple that I've seen before include "Tree of the rose family" , "Fruit with pips" , "Empire?" , "Fruit used in cider" , "Fruit from Eden?" .)
