Occasions of selling beer in a large vessel (5)
I believe the answer is:
sales
This could be a double definition.
'occasions' is the first definition.
(I know this)
'selling beer in a large vessel' is the second definition.
'sales' can be an answer for 'selling' (thesaurus). I am unsure of the 'beer in a large vessel' bit.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for sales that I've seen before include "Occasions for buying at reduced prices" , "commercial exchanges" , "Opportunities to sell" , "Marketing" , "a feature of Boxing Day?" .)
