Pitcher, flask (6)
I believe the answer is:
carafe
I believe this clue is a double definition.
'pitcher' is the first definition.
(I've seen this in another clue)
'flask' is the second definition.
(I've seen this before)
(Other definitions for carafe that I've seen before include "Wine, water, jug" , "Serving vessel for water or wine" , "Open-topped container for wine or water" , "Open-topped glass flask" , "Wine server" .)
