Vessel carrying fashionable wine producer (5)
I believe the answer is:
pinot
'wine producer' is the definition.
'pinot' can be an answer for 'wine' (eg pinot noir). I am unsure of the 'producer' bit.
'vessel carrying fashionable' is the wordplay.
'vessel' becomes 'pot' (type of container).
'carrying' is an insertion indicator.
'fashionable' becomes 'in' (in can mean fashionable or trendy).
'pot' going around 'in' is 'PINOT'.
Can you help me to learn more?
(Other definitions for pinot that I've seen before include "drink" , "Red or white ingredient" , "wine supplier?" , "Kind of wine grape" , "Black or white grape variety" .)
