Containers of flavourful Assams and kombuchas? (6)
I believe the answer is:
flasks
'containers' is the definition.
(flask is a kind of container)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for flasks that I've seen before include "Narrow-necked bottles, may be of vacuum type" , "Glass containers" , "Bottles with narrow necks" , "Narrow-necked bottles, thermos or vacuum" , "Containers for liquid, thermos say" .)
