Beer? It can taste just like tea! (4)
I believe the answer is:
brew
This might be a double definition.
'beer?' is the first definition.
(I know that beer can be written as brew)
'tea' is the second definition.
(brew can informally mean a cup of tea)
'it can taste just like' acts as a link.
This may not be right. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for brew that I've seen before include "Plot" , "Concoction" , "Make (tea/coffee)" , "Prepare (drink of tea)" , "Cup of tea (informal)" .)
