Perfect as the ale I’d brewed (5)

Ross

I believe the answer is:

ideal

Here is my best explanation:

'perfect' is the definition.
('ideal' can be similar in meaning to 'perfect')

'the ale i'd brewed' is the wordplay.
'brewed' indicates an anagram.
'ale'+'id'='aleid'
'aleid' anagrammed gives 'IDEAL'.

'as' is the link.
