Drink pints, drink repeatedly (4,3)

I believe the answer is:

pale ale

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

'drink' is the definition.
(I've seen this before)

'pints drink repeatedly' is the wordplay.
'pints' becomes 'p' (this might be a standard abbreviation which I don't know about).
'drink' becomes 'ale' (type of beer).
'repeatedly' says to double the letters.
'ale' doubled is 'aleale'.
'p'+'aleale'='PALE ALE'

Can you help me to learn more?

(Another definition for pale ale that I've seen is " Drink".)
