Such acid makes an expert twitch! (6)

I believe the answer is:

acetic

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

'such acid' is the definition.
'acetic' can be an answer for 'acid' (I've seen this in another clue). I am unsure of the 'such' bit.

'an expert twitch' is the wordplay.
'an expert' becomes 'ace' (ace can informally mean very good).
'twitch' becomes 'tic' (tic is a kind of twitch).
'ace'+'tic'='ACETIC'

'makes' acts as a link.

Can you help me to learn more?

(Other definitions for acetic that I've seen before include "Like the acid in vinegar" , "Colourless pungent acid" , "sort of acid" , "in relation to acid" , "Saucy'" .)

I've seen this clue in the Evening Standard.
