Almost sensible bottling rows, showing cunning (8)

'cunning' is the definition.
(I know that cunning can be written as wiliness)

'almost sensible bottling rows' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'sensible' becomes 'wise' (I've seen this in another clue).
'bottling' means one lot of letters goes inside another (bottling is a kind of containing).
'rows' becomes 'lines' (row can mean a line of things).
'wise' with its final letter taken away is 'wis'.
'wis' enclosing 'lines' is 'WILINESS'.

'showing' acts as a link.
