'bottles' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps there's a link between them I don't understand?

'a little drink and maybe nosh' is the wordplay.
'a little drink' becomes 'sip' (I've seen this in another clue).
'and' means one lot of letters go next to another.
'maybe' indicates anagramming the letters.
'nosh' with letters rearranged gives 'hons'.
'sip'+'hons'='SIPHONS'

'yielding' is the link.
