Unsettling experience involving lab specimens and wine (7,5)
I believe the answer is:
culture shock
'unsettling experience' is the definition.
(I know that culture shock is a type of unsettling experience)
'lab specimens and wine' is the wordplay.
'lab specimens' becomes 'cultures' (I can't justify this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'wine' becomes 'hock' (type of wine).
'cultures'+'hock'='CULTURE SHOCK'
'involving' acts as a link.
Can you help me to learn more?
(Other definitions for culture shock that I've seen before include "Disorientation caused by a complete change environment" , "unsettling change" , "Disorientation on meeting a new way of life" .)
