Producer of much bottled fruit! (4)
I believe the answer is:
vine
'fruit' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for vine that I've seen before include "Plant bearing grapes" , "Climbing plant that needs support" , "Climbing stem" , "Climbing fruiting plant" , "Climbing or trailing plant" .)
