Purity from alcohol, in essence (8)

I believe the answer is:

holiness

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

'from alcohol in essence' is the wordplay.
'from' says the answer is hidden in the clue.
'HOLINESS' is hidden within 'alcohol in essence'.

(Other definitions for holiness that I've seen before include "State of spiritual excellence" , "Piety" , "State of sanctity" , "purity" , "Goodness!" .)

I've seen this clue in The Telegraph.
