Porter, say, primarily consuming Guinness? (4)

I believe the answer is:

alec

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

'guinness?' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?

'porter say primarily consuming' is the wordplay.
'porter say' becomes 'ale' (porter is a kind of ale).
'primarily' suggests taking the first letters.
The initial letter of 'consuming' is 'c'.
'ale'+'c'='ALEC'

Can you help me to learn more?

(Other definitions for alec that I've seen before include "Smart chap" , "Sir -- Guinness, actor" , "Smart man?" , "Guinness (a smart lad?)" , "Sir - Douglas-Home, former PM" .)
