More strong beer leads to excessive retching (7)

I believe the answer is:

stouter

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

'more strong beer leads to excessive retching' is the definition.
I can't judge whether this defines the answer.

'strong beer leads to excessive retching' is the wordplay.
'strong beer' becomes 'stout'.
'leads to' says to take the initial letters.
The first letters of 'excessive retching' is 'er'.
'stout'+'er'='STOUTER'

Can you help me to learn more?

(Another definition for stouter that I've seen is " Sturdier; fatter".)

I've seen this clue in The Independent.
