Amateur work protecting calmer place where drinks are made (10)
I believe the answer is:
distillery
'place where drinks are made' is the definition.
'amateur work protecting calmer' is the wordplay.
'amateur work' becomes 'diy' (I've seen this in other clues).
'protecting' means one lot of letters goes inside another.
'calmer' becomes 'stiller' ('still' can be similar in meaning to 'calm').
'diy' going around 'stiller' is 'DISTILLERY'.
(Other definitions for distillery that I've seen before include "Plant" , "source for spirits" , "Spirited establishment" , "Place making spirits" , "Where spirits are produced" .)
