Beer Pop brewed in old Syrian city (6)
I believe the answer is:
aleppo
'syrian city' is the definition.
(I've seen this before)
'beer pop brewed in' is the wordplay.
'beer' becomes 'ale' (type of beer).
'brewed' indicates anagramming the letters.
'in' is an insertion indicator.
'pop' is an anagram of 'ppo'.
'ale' inserted inside 'ppo' is 'ALEPPO'.
'old' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for aleppo that I've seen before include "War-torn city of Syria" , "Largest city in Syria before the massive damage of the civil war" , "Lap Poe around the Syrian city" , "Tomorrow" , "Middle East city" .)
