In brewing, we hear, there's insolvency (4)

I believe the answer is:

ruin

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

'insolvency' is the definition.

'in brewing we hear' is the wordplay.
I cannot quite see how this works, but
'in' is found in the answer.
This explanation may well be incorrect...

'there's' acts as a link.

Can you help me to learn more?

(Other definitions for ruin that I've seen before include "Destroy completely" , "Dilapidated building" , "Scotch" , "dishonour" , "Destroy; downfall" .)
