Pulls out expert in beer, mostly after setback (7)
I believe the answer is:
uproots
'pulls' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'out expert in beer mostly after setback' is the wordplay.
'out expert' becomes 'pro' (short for professional. I am not sure about the 'out' bit.).
'in' is an insertion indicator.
'beer' becomes 'stout' (type of beer).
'mostly' means to remove the last letter.
'after setback' is a reversal indicator.
'stout' with its last letter taken away is 'stou'.
'stou' back-to-front is 'uots'.
'pro' inserted inside 'uots' is 'UPROOTS'.
Can you help me to learn more?
(Other definitions for uproots that I've seen before include "Eradicates" , "Displaces -- or put so (anag)" , "tears out of bed" , "Tears from natural habitat or ground" , "Completely destroys" .)
