Refreshment is but a street away (5)

I believe the answer is:

stout

I'm a little stuck... Click here to teach me more about this clue!

'refreshment is' is the definition.
I can't tell whether this definition defines the answer.

'a street away' is the wordplay.
'a street' becomes 'st'.
'away' becomes 'out' ('out' can be a synonym of 'away').
'st'+'out'='STOUT'

'but' acts as a link.

Can you help me to learn more?

(Other definitions for stout that I've seen before include "Dark ale" , "Resolute" , "Portly - porter" , "Robust; drink" , "Corpulent" .)

I've seen this clue in the Evening Standard.
